Last year I took over custody of a fine 1975 Moto Guzzi 750 S3. Its previous guardian was Luca from Toronto. Luca cared for this rare beast for over 30 years, brought it with him across the ocean from London over three decades ago and took very good care of it. Luca was gracious enough to pass the care and feeding of the S3 on to me with the knowledge that it would be loved and cared for.

Other projects are done so its time to start on the rebuilding of the S3. The paint on the tank is pretty nice for a 40 year old machine and most of the rest of the bike is in good shape for a machine that was regularly ridden. I am going to take it to a pro to see if it can be colour sanded and polished, perhaps clear coated to preserve it,

I have been taking stock of the bike for the past 6 months deciding what to do with it. I won't paint the tank or side covers but I am going to repaint the frame, swing arm and side stand. The triple clamps will be repainted, same with the instrument support.
Chrome bits are pretty good but they are pitted and showing their age, all of the chrome parts will be sent off for replating.

Rubber parts are about done, I will replace all of the rubber items,

I stripped the brakes a month ago, rebuilt the calipers and had True Disc regrind the rotors, I am slowly powder coating the rotors, new hoses and steel lines have been sourced. New wheel bearings, steering bearings and swing arm bearings will go in.
I will replace or clean up all of the misc electrical bits

I found a pair of NOS pistons and rings so I have decided to send the jugs to Millenium for coating, and the heads will get rebuilt. I will pull the crank, check the bearings, get the rods balanced, check the timing chain and fit new seals and gaskets.
I will pull the transmission and rear drive out and check the bearings, shim the shift drum and replace the seals and gaskets.

The fork tubes will get replaced and new springs, FAC dampers, seals and dust covers installed.
Plenty more to figure out.
Should be fun, a year of scrubbing, polishing, plating and painting should set it right. :BEER:

Sweet bike, looking forward to your progress.. ;-T

S3's are lovely. Don't 'Over-Restore' it, it has a nice patina of age.
Pete

Go for a ride. Winter in Canukistan will be here in another 3 months or so.. ~; :BEER: Do the rehab then so I can watch. ;D

Looking forward to following your progress, Jim! I was discussing with Luca a couple of weeks ago, and I know he will be following with interest!
Cheers,
Shaun

Following the restoration of the old girl with keen interest. You can tell her her big brother (Griso Tenni 8V) says hi.
We knew it went to a good home. Thanks Jim.

Hi Luca, sounds like you got a fine replacement with the Grisso ;-T
The Black V7 Sport gets picked up by the shipper this afternoon, there will be open floor space again in the garage so its on to the lift for the 750S3 and off with its bits and pieces!
Cheers
Jim

I know it will be tough for you, but resist doing too much cosmetic work. I like the original patina. It's a slippery slope, the more you "restore", the harder is is to stop. Next thing you know you'll be painting the tins!
Perfect bike not to sweat the chips or the weather.
-
Nice looking bike, Jim. My favorite Guzzi. Thanks, again, for your help with my project. I've passed the favor on to another member with some stuff I've been hauling around for 40 years or so...........Jack.
-
I know it will be tough for you, but resist doing too much cosmetic work.
Tough is an understatement.... I scored an amazing find last week on German Ebay - a matching pair of like new 750 S3 black and orange side covers! The originals that came with the bike will be wrapped up put away for safe keeping.
I absolutely promise to not paint the tank!
As for the rest, I don't think I can help myself, I was hoping I could leave the frame alone with its nicks, chips and surface rust, I just can't :(.
I am going to investigate getting it sprayed rather than powder coated to stick with original type finish.
The thing is once I finish restoring a bike I have no issues riding it in any conditions, I can always restore it again, no trailer queens here. :BEER:
-
There's patina and there's patina; looking at your pics, that bike's crying out for some serious tlc.
Paint work looks great, as you say, for a 40 year old, but as for the rest, I'm with you...
As for the rest, I don't think I can help myself, I was hoping I could leave the frame alone with its nicks, chips and surface rust, I just can't
I went down the powder coat route with the LM2, it's the one regret I have. Wish I'd stuck to satin black paint finish for the frame and brackets etc.

My method to restoration is to take one assembly off at a time, rebuild and refinish it and then put it away until I am ready to reinstall it. The first major group of parts to come off were the brakes; calipers, rotors, master cylinders and hoses.
The rotors went off to True Disk to be reground, fantastic service, $45 a rotor. I then powder coated the black centres of the rotors. A new set of mounting bolts were sourced from MG Cycle.
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04202_zpsodc2rqdy.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04202_zpsodc2rqdy.jpg.html)
The caliper bodies were saved but everything else was done, one piston in each caliper was seized, two seized bleeders and the seals were leaking.
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC03963_zps60ca2d23.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC03963_zps60ca2d23.jpg.html)
I stripped the caliper bodies and powder coated them, then fitted all new parts including the upgraded anodized pistons.

The front master cylinder body was very heavily pitied,
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04135_zps3e30a0d2.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04135_zps3e30a0d2.jpg.html)
I bought a better one from Mark Ethridge, I stripped it and powder coated it. Fitted a new piston kit, should be good to go.
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04204_zps0joqxtav.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04204_zps0joqxtav.jpg.html)
The rear master cylinder was pretty much done as well, corrosion on the cylinder.
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04134_zps3febbd74.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04134_zps3febbd74.jpg.html)
The cast cylinder is in pretty bad shape, not sure I am going to trust it but I cleaned it up in any event and installed a piston kit, I think I am going to fit a new one on the back as it is hidden behind the side cover and I would rather be safe than accurate ( new replacement MC are a little different cosmetically).
HMB is sending me all new steel lines and I found a set of black replacement brakes hoses from them as well.
So that about takes care of the brakes, boxed up and put away until I am ready to reinstall them.
A box of carb parts came in the mail today do I think I will remove the carbs next.

The rotors went off to True Disk to be reground, fantastic service, $45 a rotor. I then powder coated the black centres of the rotors. A new set of mounting bolts were sourced from MG Cycle.
Hi Jim, I have a question about the brake rotors. I have found that when powder coating parts, powder will be thicker on edges, particularly lower edges, due to gravity. Powder on surfaces like the mounting surfaces of a brake disc may no longer be of uniform thickness, resulting in a disc that now may show wobble or run-out.
How do you deal with this situation?
Thank you for starting another project. Your beautiful work and excellent reporting proved much pleasure to this reader.
Ciao,
Dick Casey

I think you raise a good point Dick, unfortunately I don't have an answer on how or if the powder coat may impact balance, honestly never considered it. The rotors were hung flat to bake so it may negate any localizing of powder build up to one section. No idea how to measure for balance. Hopefully I have not effected the performance.
Cheers
Jim

Congratulations! That's one fabulous (...and RARE) model Guzzi! Restore it, sort it, ride it, and most of all enjoy it! She deserves to be ridden and "In The Wind" again! 8) ;-T :)

A day out of the office and quality garage time. Today he carbs came off and were stripped.

Then 2 hours in the ultrasonic cleaner with ultrasonic cleaning solution
Comes out like this, super clean, and new fasteners, needles, O rings, gaskets, and springs

And they are done, the ultrasonic solution does a fine job of cleaning up the castings without any soda blasting
I have resisted polishing the castings and finish them like they came out of the factory

Curious to see what the heads and cylinders look like
-
Pulled the heads and cylinders this morning
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04317_zpsgkt93aiu.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04317_zpsgkt93aiu.jpg.html)

No big surprises but the cylinders are flaking as suspected
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04318_zpsxaygdxm1.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04318_zpsxaygdxm1.jpg.html)
Harpers supplied a pair of NS pistons and rings so I am going to save the original cylinders and send them off to be re-plated
MG supplied valves, springs and guides
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04320_zpsm6aauqgl.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04320_zpsm6aauqgl.jpg.html)
After I strip the heads and soda blast them they will go to a machine shop to cut the valves seats
Lifters look good, push rods are straight, but the rocker pins show a lot of wear at the top half on all four, I think a set of new ones are in order.
Next to pull the engine and transmission out
-
:pop

Got a little more done in the cleaning and prep of the heads and cylinders, it was off to the car wash with a 50/50 solution of water and NAPA Aluminum Brightener in a spray bottle. Several soakings later and a quick blast with the high pressure wand an inch off the casting and they come clean
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04323_zpsz1kxe81h.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04323_zpsz1kxe81h.jpg.html)
Then back in the lane after the parts thoroughly dried a quick going over with a soda blast and the remnant of oxidation and the carbon in the head exhaust tracts are gone.
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04324_zpsbkpismqr.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04324_zpsbkpismqr.jpg.html)
If you have never used a soda blaster it is amazing, all you needs is a 5 gallon pail of soda and a siphon spray gun from Harbour Freight, as the soda particle hits the part it explodes and knocks the detritus off the surface instantly.
These rocker covers were still discoloured after chemical washing, a pass over of the soda and like new

The heads go to the machine shop this week and the cylinders and new pistons/ rings off to the Canadian branch of Millennium Coatings in Manitoba.
I soda blasted the rockers to clean off the years of oil crud the ultrasonic cleaner could not budge

Some wear on the pressure surface but I think they are still serviceable
One of the lifters has lost its hard surface and the rocker pins are scored but the ridge is where the spring rides on the pin so again I think they are ok to reuse

Loving this!

Continuing with the disassembly, the S3 switches are shared with the T and the Le Mans MK I, fragile and complicated little buggers. Guzzi chose to feed the wires through the clip on handle bars then cover them in a plastic sheath and fit a multi pin plug on the end. Each ping has to be pulled out of the plastic holder by squeezing the tang on the pin to release it.

This bike was manufactured for the European market and unlike the V7 Sport and other American market bikes the tag on the frame does not match the number on the block

The European bike frame is also stamped to match the metal tag riveted to the headstock
Fork tubes are pitted and rusting

New ones are fairly reasonably priced and FAC dampers and progressive springs will be fitted.
Centre stand has a leg broken off

All the parts needing re-plating have been gathered up and will sent off for new chrome.

Thanks Cam but I don't know any hot gals willing to pose in birthday suits for me,... and Mrs. Canuck would definitely kaibosh any such form of cycle promotion. The only pair of jugs in my shop are aluminum castings. ;D

I spoke with Fast Industries (the Canadian branch of Millennium) in Manitoba, after a short discussion I mailed off the original cylinders and two NOS pistons, they will plate the bores and size them to the pistons. I also sent them the heads, new guides, valves and springs plus the retainers, spring shims and caps, they will grind the valve seats and shim the valve springs, and I asked them to deck the heads while they are in there.
So back to the garage, the swing arm pins came out easily, thank goodness

And the various side stand parts

The U joint is toast, one bearing cap has collapsed and the rollers are sitting above the carrier bearing with lots of detritus, the U joint wiggles back and forth a good 1/4", yikes!
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04355_zpsarh4xt1b.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04355_zpsarh4xt1b.jpg.html)
Carrier bearing was really in tight, removed the circlip and broke out the trusty slide hammer blind bearing puller and a lot of violence
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04353_zpscel7wdri.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04353_zpscel7wdri.jpg.html)
Carrier bearing is good, thought the shot U joint would have given it some grief
Then the pivot bearing seats
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04354_zpsxlambhbx.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04354_zpsxlambhbx.jpg.html)
The tapered pivot bearings are notched, into the bin they go
Back to the frame, motor fitted the engine stand on the hoist, hang the frame from the overhead rail and then drop the lower frame rails and lower the hoist and down comes the engine and transmission

Off come the fork tubes then the upper triple, the head stock nut was finger tight
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04359_zpslldvu72j.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04359_zpslldvu72j.jpg.html)
Bearing stuck, a block of aluminum and a whack of a big hammer and the stem and lower clamp are free
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04360_zps1s8wdhst.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04360_zps1s8wdhst.jpg.html)
Bearings are notched, more parts for the bin
This handy tool is for driving out head stock races, works great every time, slip it into the frame, push the tangs down onto the race and whack the top of the tool, out comes the race with no damage
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04361_zpsmaal28wk.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04361_zpsmaal28wk.jpg.html)
Just a few more big assemblies to strip, wheels, engine and transmission
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04365_zpszpmpahlw.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04365_zpszpmpahlw.jpg.html)
Then I just have to clean, replace, paint, plate, polish and put it back together, easy

Goy my copy of Real Classics in the mail today, thumbed through it but haven't read the S3 article yet.
The engine disassembly has started off on a rocky road, one pan bolt head stripped, had to drill it out

I should have removed the crank nut before I pulled the flywheel off and used the ring gear retainer to lock the crank, damn that nut was on so tight!! I pinched the chain with a steel dowel in a sprocket, can't believe how much force it took to get that nut off

Between a morning at the office and late afternoon doing spring yard work I got an hour in to take the wheels into a shop to have the tires removed, the pulled the main bearings and removed the crank and cam. No obvious trouble but I still need to measure both.

Cause I like blue tools?? I had a container of Ford blue powder, and being a OCD nut job I just wanted all of my tools blue :D
I got the block cleaned up, three soakings of NAPA Aluminum brightener, a truck wash high pressure blast after each soaking and the aluminum is as clean as the day it came out of Mandelo.

I masked off the bearing surfaces of the front and rear bearing flanges and treated them to the same cleaning process, ditto the oil pump
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04394_zpsnzoumrnv.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04394_zpsnzoumrnv.jpg.html)
I removed the crank sludge trap plug and dug out the crud, surprisingly very little sludge, the Eldo and two V7 Sport motors I have rebuilt were packed with crud, testimony to what a proper oil filter can do for a motor

After emptying an aerosol can of brake cleaner in the crank recess the crank is clean
Measured the three bearing diameters

Thank goodness all three diameters are within spec, but the rod pin is just in tolerances so I will install a new set of con rod shells, This saves me at least $600.00 on a crank grind and new bearings.
Luca you looked after this motor, ;-T

somehow I feel like a motorcycle cowboy when I see a mancave dripping with tools and stuff like that..an ultrasonic what...sounds like my doctor..here I am with basically the tools that come with the bike, and afew rusty old spanners...I am oozing jealously
-
Hi, Jim.
I'm going to try your cleaning method next weekend. Would you mind telling me what you used to mask off the bearing surfaces? It seems to me that almost anything would come off with the pressure washer. Maybe you are only worried about when the aluminum brightener is applied, and it doesn't matter once you start to spray?
Thanks for the great tutorial!
Shaun
-
Hi Shaun
I mask off the bearing surface with plain masking tape, press it on tight and then spray on a 50/50 solution of water and aluminum brightener, wait at least a minute, the aluminum will foam up white, then hit it hard with as high a pressure as you can find.
Make sure you are wearing a full face mask and that the respirator is for a chemical type, mine is a good quality but I think I need new canisters as my throat is a little sore from the chemical irritation, I sprayed with a hand spray bottle outside in the lane with little wind. This chemical brightener is very serious stuff, take caution and wear rubber gloves.

You know the problem with a coin-op car wash is that some impatient guy or gal in line always opens the overhead door before I am done washing, just to push me along, having this respirator on, my big green industrial rubber gloves and a yellow rain suit bib overall on really gets their attention, you bet they close the damn door quickly when I yell out don't breath!!
I think I look like a character out of some Breaking Bad episode in the meth lab ::)
At least no has called the cops yet.

I guess that NAPA goo would not be the thing to clean up the outside of an old dirty engine..would eat the gaskets yeah?? I feel such a rookie at this restoring lark..

No problem using the aluminum brightener on a complete bike, it will not harm the gaskets, BUT.. it will discolour plastic, especially black plastics and black paint. Will not hurt rubber and I have not seen it discolour black frame paint. It will discolour the Brembo caliper paint. If you use a spray bottle that you get in any hardware store with a mist spray had (use an empty window cleaner spray bottle) and a 50/50 solution and be careful to just wet the areas you want to clean you will be good. The Brembo calipers can be masked off with clear plastic kitchen wrap or even plastic bags. Bare metal will turn a gold colour. Work in small areas and be sparingly with the spray of cleaner. As high a pressure wash as you can find is the trick. The 1st photo of the bike is after I cleaned it with brightener prior to disassembly.

I worry about using any chemicals such as that, even at the car/truck wash. Even when diluted, they're still nasty, hopefully the waste water treatment plant has means of neutralizing it.
-
Copy that Canuck...thanks for sharing your knowledge..
will try a wee drop at a time, when I get my hands on some of the stuff, and when my bike sails in.
yup I hate chems at anytime, but it does a nice job..just dont wash it into any near by stream neh..
-
The Aluminum Brightener is the same stuff you get in a spray bottle of Aluminum Mag Wheel cleaner, except of course this NAPA stuff is not diluted, I think the off the shelf mag cleaner is at least 25/1 diluted. By the time I spray the guck off I have diluted the mix down to at least 25/1 so it can't be any worse for the environment than what else goes on at a car wash.

That just leaves the transmission and rear drive the strip and check.
Fast industries ( Canadian affiliate of Millennium) called today to say they received the original cylinders in the mail, confirmed to be in good shape and suitable to re-plate and they will deck the heads and seat the new valves and shim the valve springs to spec.
Chrome bits that need chrome re-plating are sorted, they will go out this week.
The frame and associated bits will get sent to the bead blaster before the weekend.
A Guzzi is definitely greater than the sum of its parts

Hah
Taking a bike apart is the easy part ;D The getting it back together, ....well that can take a bit longer. I have taken at least a hundred pictures so far so I can hopefully get it back together.
Cheers
Jim
-
yes amazing work..what do you do in your spare time?
-
Well I don't watch much TV, and I am usually in my office 6 days a week and sometimes 7, running my own business doesn't leave a lot of time for much else, but this bike building is how I relax and leave 'work' at the office. Working with my hand's has always been a source of relaxation and reward. An hour or two a day, when I can, in the garage and I just plug away until its done, then on to the next one.
Cheers

Jim,
What's your logic for using the NOS side covers on the bike and stashing the originals?
Why not use the originals that will match the tank, and sit on the NOS?
They're only "NOS" once. You do plan to ride the bike.

Good on you Jim,
i for one appreciate your story and pics. I have a task in front of me, pulling the crank out of the zuke 750 GT. meaning a complete engine strip. I can't yet find the energy to do it after a 4 year restoration. maybe this weekend ?

You are right Cam, I got that backwards, NOS get put away and I clean and polish the stock side covers to match the tank. (I should be sleeping but I have to drive family to the airport in 20 minutes ::))
and I will definitely be riding this bike, no trailer queens here.
I got a Brown side stand in the mail today for the S3, what a great piece of kit.
Cheers

I can relate to that, I can procrastinate for a long time over a daunting task and when ready throw all caution to the wind and dive in ;D

Okay, that makes sense. Brown side stand was the first thing I added to my LeMans. Love it!

Time to strip the transmission
Home made clutch spline tool from an old clutch plate and a 4 prong socket from Mg Cycle

Now the rear cover can pop off and a shaft comes with it

The bearings in the cover don't feel good, they feel to all have a notch, the bearings need to come out, into the oven until the cove reaches 350 F
(http://i249.photobucket.com/albums/gg217/canuck750/DSC04422_zpsjtdekv7g.jpg) (http://s249.photobucket.com/user/canuck750/media/DSC04422_zpsjtdekv7g.jpg.html)

And the case bearings also feel rough
(http://i249.photobucket.com/albums/gg217/canuck750/DSC04427_zps3o8czhdn.jpg) (http://s249.photobucket.com/user/canuck750/media/DSC04427_zps3o8czhdn.jpg.html)
Examining the gear sets there is a lot of wear at this point on each of the corresponding gears

I got off lucky with the engine crank and main bearings being in spec, unfortunately the transmission needs a full set of case bearings and the gear sets are not the best.
(http://i249.photobucket.com/albums/gg217/canuck750/DSC04429_zps3hxw4unm.jpg) (http://s249.photobucket.com/user/canuck750/media/DSC04429_zps3hxw4unm.jpg.html)
Next the rear drive, fingers crossed

Love it ;-T

I sealed up the empty transmission case and took it to the car wash for a blast of aluminum brightener, waiting on a full set of bearings to arrive.

While the transmission site on the backburner I stripped the forks, an impact makes the job easier
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04432_zpsztkabzna.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04432_zpsztkabzna.jpg.html)

The dampers are very weak, I will replace them with new FAC dampers and progressive springs, the dust caps, and tubes will be replaced as well, only the fork lowers, caps and damper rods are salvageable.
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04438_zpsvmalnfsl.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04438_zpsvmalnfsl.jpg.html)
Whatever paint Guzzi used on the fork lowers it's damn hard to get off, bead blast hardly touches it, I ended up sanding the paint off then touching up with a glass bead blast, polished the alloy tops and masked for powder, ... I forgot to order the silver powder >:(
All the small painted brackets, fork clamps, headlight shell and gauge mount were stripped and powder coated satin black

Wheel rebuilding is a lot of work and my least favorite part of rebuilding any bike, 40 spokes, 40 nipples, corroded rims, hubs that need cleaning and the bearing carriers to freshen up, X two.
40+ year old wheels are not easy to strip , looses each spoke a few turns with a wrench
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04447_zpszktkli3t.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04447_zpszktkli3t.jpg.html)
Then back the nipple off a few more turns with a flat blade
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04448_zpsixerse9p.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04448_zpsixerse9p.jpg.html)
Then a short rap with a hammer on the flat blade to crack the spoke free from the hub
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04449_zpsooskmnnu.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04449_zpsooskmnnu.jpg.html)
Always a couple spokes that are not going to loosen without heat
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04451_zps45d7bkej.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04451_zps45d7bkej.jpg.html)
Only 4 bent spokes, I have spares
no visible cracks in the hubs or rims
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04452_zpsjzndwjew.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04452_zpsjzndwjew.jpg.html)
A soda blast to the inside of the rims and the hubs strips off the corrosion in the spoke recess
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04453_zpssckz1frw.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04453_zpssckz1frw.jpg.html)
Now to polish 80 spokes, 80 nipples and two rims, and then lace and balance, new rim tape, new tubes and tires, A Guzzi engine rebuild is easy compared to this.....
-
love the pics Klondike...keep them coming as I have to attack a wheel for my first time soon..apparently the drive spindle is worn, so on the lookout for replacement..love the soda thingy..does wonders..do you find the alum goes dark grey again over time??
-
Hi Maaka,
The cleaned aluminum will oxidize and turn darker gray over time. I coat clean alloy with ACF50 once the parts are assembled, it gives at least 1 year of road use protection.
cheers
Jim

Going to get the wheel building behind me, it's the last of the 'dirty' jobs.
Fine brass wire wheel in the bench grinder, then rouge polish on a buffer wheel, 80 spokes and nipples freshened up,
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04455_zpsqjlavvov.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04455_zpsqjlavvov.jpg.html)
Then to polish the back rim, it makes one heck of a mess to make it shine again
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04456_zps8bupknns.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04456_zps8bupknns.jpg.html)

A little anti-size on the end of the spoke that fits into the hub, one day someone will restore this bike again and hopefully the spokes will be a little easier to get out
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04458_zpsxz3quxz5.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04458_zpsxz3quxz5.jpg.html)
Guzzi wheels are so easy to assemble compared to a Japanese wheel with hooked spokes, usually 4 different types per wheel

and cleaned up the rubber dampers
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04462_zpsfabaim07.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04462_zpsfabaim07.jpg.html)
Then the big plate
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04463_zpsezesgyr9.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04463_zpsezesgyr9.jpg.html)
Then to squeeze the plate into the rubbers so the great big snap ring can fit
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04464_zpsefgrqrbf.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04464_zpsefgrqrbf.jpg.html)

Snap ring pops in and the lock tab to keep it there

-
Wow you really made that thing shine
-
Thanks! I spent about 20 minutes buffing the rim, by pre-treating it with Aluminum Brightener 1st and getting the oxidation off, the polishing is much, much less work, that and the fact that the rim was in pretty good shape to begin with.
Cheers
Jim

I was considering buying new stainless steel headers and cross over, the discolouration, stains and pits looked pretty ugly
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/PA080039_zps23f0388f.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/PA080039_zps23f0388f.jpg.html)
I want to keep as many of the original parts as possible so I tried polishing the parts with several different grits of polishing compound. After a couple hours working on the two headers and cross over I am very surprised that they cleaned up pretty good, they are stainless to my surprise and though they are not 'like new' the finish suits the bike,
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04470_zpsmf6bggkz.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04470_zpsmf6bggkz.jpg.html)
Polished up the rear fender, bead blasted the rust of the steel brace and brushed Tremclad over the raw steel,
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04468_zpswdjzojmz.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04468_zpswdjzojmz.jpg.html)
A good portion of the bike's components are shipped off for engine machine work, cylinder plating, flywheel lightening, cad plating, chrome plating and the frame is out for painting, now to wait for it all to come back and then it's just reverse the order like the manual says and put it all back together, simple at this point. ::)
-
Those stainless parts you polished look like they are chromed ;-T
-
I enjoyed rebuilding my Mille's front wheel. The amazing thing was the way the hub guided each cleaned and polished spoke right to its rim hole without having to think about lacing at all. Much better than the usual spokes with a ≈90° bend at the head, and a drilled flange on the hub. I have a feeling you liked doing it more than you let on. ;D
-
Guzzi wheels and spokes are brilliant, why other manufacturers' have not copied the simple straight pull spoke is beyond me. I have laced a lot of Yamaha and Honda dirt bike wheels, 4 different spokes per wheel, much, much more work. A guzzi wheel is really not even laced, more like just assembled.
I admit that I may not like building wheels but the end result is more than worth the aggravation. :)
-
Mate, you are real bike wizard, and I just sit here with my mouth hung open, and in awe of you work, and workshop..Wish I lived just around the corner...hahaha
-
Thanks for the kind words Maaka,
I got a replacement wheel in the mail today from a fellow guzzista; thanks Jack. A blast with the high pressure baking soda to remove the surface oxidation, and the scum in the spoke holes, then a 200 grit sanding pad on a foam palm sander to get rid of the deep scratches and touch up the edge of the rims, and it will polish up very nicely.
Baking Soda is my friend!

I used a drum sander to remove the powder paint out of the inside of the center cut out of the discs so they will slide over the bearing carriers

Spacer fits in here

I use an old feeler gauge to protect the fresh powder coating on the disc to bend over the lock tabs

Front wheel ready to be trued prior to new rim bands, tubes, and tires
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04487_zpsnv9tnvpm.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04487_zpsnv9tnvpm.jpg.html)
But the rear wheel has me stumped, the bearing carrier fit in just right and the rear disc popped over the carrier, when I flipped the wheel over to install the spacer it sticks up to far???
Rechecking the front wheel the spacer is fitting just right between the two front bearings, so I think I have the front wheel carriers and spacer in correct.
I need to check my parts manual (at the office), I think this piece goes here (with the spacer inside the hub center) and then the sealed bearing goes into the recess
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04491_zpsfzfahr21.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04491_zpsfzfahr21.jpg.html)
I took lots and lots of pictures of everything else as I disassembled it, except the wheels, because they are straight forward :beat_horse :beat_horse
-
I believe that spacer goes on the outside of the bearing, between the bearing and the caliper carrier. The smaller diameter goes towards the bearing.
You are doing very nice work. I wish I could have bought your black Sport when it was available.

I looked through my 750 S3 part book (just a short supplement to the 850 T3 parts book), the rear wheel is the 850 T3 assembly with no changes
Part #25 is the 'CUP' - the flanged washer, it fits under the bearing against the spacer, it may be the piece that is already in the cast crush drive plate in my pictures and the flanged thick washer in my hand maybe goes somewhere else??? I recall a piece, probably the mystery flange / washer fell of the rear wheel as it was propped up against a wall. The tube spacer length just seems odd in the rear wheel hub.
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/850T3%20Rear%20Wheel_zpszxmn5dll.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/850T3%20Rear%20Wheel_zpszxmn5dll.jpg.html)
The front wheel on the S3 uses the bearing flanges as the rear wheel on the 850T3, but the bearing spacer tube is from the 850 T3 and the front and rear wheel bearing spacers tubes have different part numbers.

#25 is called a "grease cup" by S-D and looks like this:

(http://www.stein-dinse.biz/images/product_images/info_images/17633550_01.jpg)
The "thick flanged washer" is #19 and goes where Mark said it does.

Thanks Charlie!
So it appears to be set into the cast splined plate already, the new bearings are sealed. I wonder if the purpose of the 'Grease Cup' was for the use of non sealed bearings?
Do you pop out the sealed bearing faces and grease them and use standard type grease seals or just keep use sealed wheel bearings?
Jim

I love your posts!!!!

I always stick with whatever type bearing is installed from the factory. If it's sealed, that's what I replace it with.

Thanks Charlie, I just want to be sure. ;-T

I figured out the rear wheel, thanks to Charlie and Mark, on the S3 the bearing tube spacers are slightly different lengths front to back, the rear being about 1.5mm shorter, once swapped it all falls into place, and the rear outer wheel bearing sits into the flange as it should.
Trued the rims with a dial gauge, pretty easy on a straight pull spoke rim, I try to get to 20 thou up/down and L/R. I think the rubber tire typically balances out the variance, I have no real idea as to how accurate the factory spec on the rim is supposed to be, anyone know??

Got some of the small bits done, mostly the electrical support brackets, diode, regulator etc, just soda blasted the coils and then sprayed them to look like gold cad plating, the reg was painted and a band of yellow electrical tape goes around the bottom (could not find the blue but I have seen yellow banded Bosch regulators as well). Reused the diode board, new rubber bits and cable clamps.

I decided upon powder coat for the frame, could not find a shop willing to spray the frame with an epoxy satin black for a decent price, quick turn around, got the frame back from the professionals today.
The fork lowers were done in the garage with my Eastwood Automotive powder coat kit and used Eastwood Rally Wheel Silver

The old tubes were pitted and rusted, the stock dampers about as strong as a screen door damper and the springs a good match to the rest of the old parts.
New fork tubes, progressive springs, FAC dampers and new fork wipes and seals.
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04521_zpsx5v9ghsv.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04521_zpsx5v9ghsv.jpg.html)

Bead blasting the fork tubes caused the inside of the tube to become rough and the fork tube binds so I made up a long extension to a sanding wheel and then ran the wheel in a drill to polish the inside of the fork lower

This is what I came up with to get 50cc of fork oil into the sealed fork assembly, by slowly pumping the fork the fluid is sucked in through the drain hole, the fancy little funnel is from a medical IV tube, my wife is a nurse and years ago she brought me a big bag of out of date supplies form the hospital, finally came in handy.

Fitted the forks into the triple clamps, waiting for the headlight ears and clip on handle bars to come back from the platting shop, so the tubes will come out once more.
I stopped into a bolt supply shop to find new dome rivets, they are '#4 X 3/8" self seating fasteners', fit the S3 frame tags perfectly, much larger than the rivets on the V7 Sport and Eldorado and Guzzi used only 2 instead of 6 on the S3, DeTomaso cost savings??
The FAC dampers have air fittings, I need to replace these with 8mm threaded special bolts to accept the instrument cluster.

Pulled the shocks out of the bin, they look pretty decent
a little rust on the shock body
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04541_zpsav59ndrm.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04541_zpsav59ndrm.jpg.html)
These are Paoli shocks, they come apart from the bottom, the cast aluminum adjustment ring turns and lifts off the shock body when the spring is compressed.

One of them is leaking, the seal is done and these are not rebuildable, the shaft is welded to the top of the shock and the body is sealed.
So I will need to find something modern to use for riding and keep these for show.
They painted up good and the chrome polished up fine.

These Aprilia signal lights are so well made. cast bodies, steel chrome stems with locking buts and lucking plugs to secure the body to the threaded stem in the correct position, but the best part is the lamp holder is mounted on springs to isolate it from the cast body, very cool

I am an avid follower of this thread and get a kick out of seeing your progress. I sent my threaded shafts that the turn signals mount on away for plating when I did my T3. When they came back the threads had been eroded by some part of the plating process to such a degree that they were ruined. They were made from some sort of muck-metal. I got around it by using threaded rod with stainless tube, thus being able to shorten the front ones. Check yours carefully before you send them away.
-
Thank you for the heads up on the plating!
I will check wit the platting shop about what they can and can not protect.
Cheers
Jim

The forks have to come apart, the tops of the FAC dampers need to be modified to accept the instrument cluster special bolt, I modified a set of FAC dampers to fit my disc brake Eldo so I know there is a lot of aluminum in the top of the FAC damper.
On the left is the FAC, on the right is the stock fork cap for the S3 (same as the V7 Sport)

My small lathe comes in very handy for small projects like this, first the hex head of the FAC is too thick, machine it down to match the stock plug

Then drill and ream out the center of the plug
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04552_zpsmj8xk80g.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04552_zpsmj8xk80g.jpg.html)
And thread the centre for the 8mm special bolt
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04553_zpsi89nvefs.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04553_zpsi89nvefs.jpg.html)
and now the new matches the look of the old
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04555_zpscb9vtviw.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04555_zpscb9vtviw.jpg.html)
A little thread sealer
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04556_zpsjqqndhnt.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04556_zpsjqqndhnt.jpg.html)
And they are done
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04557_zpsze3yn1qc.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04557_zpsze3yn1qc.jpg.html)
Back together, much better, it would be very hard to tell that the forks are modified to FAC dampers
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04558_zpsspgt36zc.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04558_zpsspgt36zc.jpg.html)
Stripped the rear end, gears and bearings are very nice

The case just needs on helicoil for the lower drain plug, the case alloy is very soft, no wonder the plugs strip so easy
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04562_zpsz8rudngl.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04562_zpsz8rudngl.jpg.html)
A little permanent locktite on the coil

the paper gaskets were brittle, new ones with a tiny bead of silicone
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04566_zpspceenhlw.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04566_zpspceenhlw.jpg.html)
And torque it all back together and fit a new seal

These pics are Great ;-T

I reused the original pivot bearings and races, I figure that as long as they are decent a good cleaning and re-packing them with grease will serve for another 40 years

Thanks for the awesome step by step pictures, they're a great guide for when mine comes together :bow
-
Lovely ;D
-
The time it takes to build, plus pics and comments. Just awesome.
-
Thanks guys for the encouragement, the beauty of a Guzzi big twin is they are very simple to work on, if an untrained guy like me can put one together I think anyone with some time, patience and asking timely advice on this forum can rebuild one. The 4 stroke Honda motor on my old gas mower was more complex.
A big box arrived today from Fast Industries in Manitoba, (Millennium branch office in Canada),turn around was about three weeks door to door, just like Christmas in May ;D
Cost on the cylinders was about $300 CDN each, factor in new pistons (Harpers has lots of new pistons and rings for the 750 Sport, 750S and 750 S3) and new rings, gudgeon pin and circlips and it's the same price as Giladorni kits but I have retained the original cylinders for this bike.
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/P7120002_zpslqzaf4fl.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/P7120002_zpslqzaf4fl.jpg.html)
I had sent the original 750 S3 cylinders and heads off to be rebuilt, the cylinders were plated and matched to new pistons I sent along. The shop marked the pistons and cylinders as LH and RH sets
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/P7120003_zpssfwuo4ux.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/P7120003_zpssfwuo4ux.jpg.html)
Heads were sent with new guides, valves and springs, they replaced the guides, ground the valve seats and shimmed the springs for each valve and fitted some Helicoils. Price per head was a little over $100 CDN + parts cost for valves, springs and guides.

Now to assemble a motor, MG Cycle provided a new B10 cam on exchange for the stock cam and supplied a new timing chain and tensioner along with a bunch of small items like rod bolts, cam retainer etc...

In advance of assembling the engine there are a couple of housekeeping items that I learned from Gregory Bender and his excellent 'This Old Tractor' web site. Greg has amassed an amazing body of knowledge on all things Guzzi and anyone working on an old Guzzi really should take a read through the site. Loop frames are his specialty but the early Tonti models are well represented.
First to flatten the base of the engine block, I don't have a real surface plate but I have a nice piece of granite tile that I checked with a straight edge and a feeler gauge, pretty darn flat as is.
I use 200 grit dry sandpaper and spray glue to mount the sand paper to the granite tile.
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04582_zpshk8cs6q7.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04582_zpshk8cs6q7.jpg.html)
Then I brush on some machinist blue dye to mark the base of the engine block
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04583_zpsemrtvch8.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04583_zpsemrtvch8.jpg.html)
Then place the block onto the sand paper / granite and pressing down on the cylinder studs I rotate the block and slide it side to side and back and forth, in a couple minutes all the blue dye is gone and the surface of the block is true
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04584_zpstxrjm5o5.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04584_zpstxrjm5o5.jpg.html)
Last thing to do on the block is to mix up some JB weld and seal the cam plug, the JB weld is self leveling, I use just enough to fill the recess in the block around the plug
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04585_zpstvwgvsvo.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04585_zpstvwgvsvo.jpg.html)
Ready to start assembling the motor.
-
1st off let me be clear I am no mechanic, these pictures are just a record of how I go about assembling a motor, hopefully I am doing this right.
Fitting the crank shaft and flanges, oil feed tube still intact
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04586_zpsehm8wn0v.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04586_zpsehm8wn0v.jpg.html)
Heat the case with a heat gun for a couple minutes and the flange will drop in to place without binding
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04588_zpspq4qhihu.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04588_zpspq4qhihu.jpg.html)
Pre bend the new lock tabs before setting the 8mm bolts securing the flange
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04589_zpso0j4vvv0.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04589_zpso0j4vvv0.jpg.html)
These four are secured and the remaining two will come out once I fit the cam chain tensioner and then be brushed with Loctite and torqued to spec
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04590_zpsu1vn9mok.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04590_zpsu1vn9mok.jpg.html)
Brush the mating surfaces with Assembly Lube
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04592_zpsaxdbszdt.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04592_zpsaxdbszdt.jpg.html)
And the bearing surfaces of the crank shaft
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04593_zpsdcboqgx8.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04593_zpsdcboqgx8.jpg.html)
The I fit two studs to hold the rear flange gasket and again heat the case
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04596_zps7bijpvmn.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04596_zps7bijpvmn.jpg.html)
And check the rear oil feed tube is in place
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04597_zpscflckkgj.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04597_zpscflckkgj.jpg.html)
Rear flange drops into place
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04598_zpsriuzffbp.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04598_zpsriuzffbp.jpg.html)
Bottom two bolts need tread sealant or oil will leak out of the back of the motor
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04599_zps7bmjxh9e.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04599_zps7bmjxh9e.jpg.html)
Locktite on everything that can rattle loose
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04600_zps6wnlv7l3.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04600_zps6wnlv7l3.jpg.html)
Press the rear main seal into place using this home made aluminum and long bolt kit
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04602_zpssxhntdj3.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04602_zpssxhntdj3.jpg.html)
Aluminum crush washers on each side of the lower breather tube bolt
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04603_zpschuckvek.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04603_zpschuckvek.jpg.html)
New con rod big end shells, and new con rod bolts and nuts
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04606_zps6p4zcuzn.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04606_zps6p4zcuzn.jpg.html)
Torqued into place
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04607_zpsrzgfonnk.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04607_zpsrzgfonnk.jpg.html)
B10 cam from MG Cycle
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04608_zpsqmof5rti.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04608_zpsqmof5rti.jpg.html)
A new cam bearing flange
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04609_zpswonaqldp.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04609_zpswonaqldp.jpg.html)
And then an hour later I finally got the continues new cam chain and three sprockets to drop over the three shafts at once, 1st time I installed a cam chain, the gear sets on the Eldo and V7 Sport is far superior in my humble opinion.
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04612_zpsc0npxm69.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04612_zpsc0npxm69.jpg.html)

Got in an hour in the shop yesterday, unpacked the replated cylinders and rebuilt heads.
reusing the lifters, they are in nice shape, only one has some minor wear but I am not opting to get them ground
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04617_zpsdnxs0cay.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04617_zpsdnxs0cay.jpg.html)
The new rings I got from Harpers (along with the pistons) come marked with 'TOP' on the ring surface, no confusion about getting them right
Millennium measured each piston and matched the plating / cylinder sizing to each piston individually, there was a few thou difference between the two
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04618_zpsdezbyyak.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04618_zpsdezbyyak.jpg.html)
And these gaskets from MG Cycle align nicely with the push rod tubes, some others I got out of 'kits' don't line up very well
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04619_zpszyxs9z5x.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04619_zpszyxs9z5x.jpg.html)
New O rings
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04620_zpsokl5runp.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04620_zpsokl5runp.jpg.html)
And I replaced the wave washers
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04621_zpsxxbgowdv.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04621_zpsxxbgowdv.jpg.html)
Torqued all six head nuts to 31 ft.lbs.

I polished the original rocker pins and rocker wear surfaces, used a white polish and the small imperfections cleaned right up

Nice and snug rockers

I got started on the 5 speed, new bearings for the case and cover, I get to try out the bearing drifts I bought off a chap in Germany and I made up three other ones for different bearings
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04635_zpsice4lrco.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04635_zpsice4lrco.jpg.html)
I heat up the cover and case to about 250 F,
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04638_zpsowtbwyrt.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04638_zpsowtbwyrt.jpg.html)
then a smear of retainer on the bearing surface
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04636_zpsgkghxoh4.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04636_zpsgkghxoh4.jpg.html)
Cold bearings drop right into a heated case and cover, a final tap on the drift to make sure the bearings are seated
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04637_zpsc1kxrhco.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04637_zpsc1kxrhco.jpg.html)
Getting the races off the ends of the shafts was a real bugger! Tried the butane torch, didn't budge at all
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04641_zpsjtchtwcf.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04641_zpsjtchtwcf.jpg.html)
It took the oxy acetylene torch to get the race red hot and the bearing puller to remove them
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04642_zpstggrjurk.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04642_zpstggrjurk.jpg.html)
at least the new races went back on without too much drama, just warmed the races up wit a heat gun to 160F, a smear of locktite retainer and the special Guzzi tool to drive them home
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04644_zpse1mkaqbt.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04644_zpse1mkaqbt.jpg.html)
And the bearings are replaced
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04645_zps8ervwoum.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04645_zps8ervwoum.jpg.html)
short of the one big end bearing on the main shaft, that is for another day
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04646_zpszp2fzfqc.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04646_zpszp2fzfqc.jpg.html)
Now to shim the selector drum and reassemble the gear set
-
Replaced the transmission shaft bearing, the special nut on the end of the shaft is reverse thread and it is 'punched' into a recess in the shaft, straighten the nut and it spins off with little effort
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04655_zpsbyhg4yrc.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04655_zpsbyhg4yrc.jpg.html)
From MG Cycle I bought a deep sump with a recessed external oil filter, nice kit, comes with everything needed to make the swap
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04648_zpsahmwbktd.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04648_zpsahmwbktd.jpg.html)
No instructions but the relief valve and the plastic / mesh screen needs to be swapped from the stock pan
The relief valve will not fit if the shroud is left on
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04649_zpserlnalt4.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04649_zpserlnalt4.jpg.html)
So I removed the shroud and added a shim equal in thickness to the shroud
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04650_zpsk7ks9tat.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04650_zpsk7ks9tat.jpg.html)
I like it, the oil filter is fully recessed below the deep cooling fins
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04651_zpsejo5mmcj.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04651_zpsejo5mmcj.jpg.html)
The yellow tape reminds me I need to torque the timing gear nuts once I get the flywheel, clutch and ring gear on and I can lock up the motor.

Then drilled out the old steering lock and installed a new steering lock
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04502_zpstyud7uwb.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04502_zpstyud7uwb.jpg.html)
Hi there, love what you are doing here.
Question, if i may,
1: After drilling the lock out, how is it retained in there...?
2: Where do you get the locks from...?
I would like to do this for the Monza i have....
Thanks Warwick :)

Once you drill out the soft brass lock cylinder any remnants of the lock will pull out with not too much effort. The new lock is retained by a spring loaded tab, you insert the key, turn the key hard to one side (can't remember if you turn R or L) push the whole assembly all the way, release the pressure on the key and centre the key in the position that will release it, remove the key and cylinder will remain locked into position. To remove the cylinder re-insert the key again turn hard to the R (or L??) and pull the whole assembly out with the key in the cylinder.
MG Cycle has the steering lock for the Monza in stock

It should be noted that the fork lock cover needs to be removed as the first step. A thin, flat-bladed screwdriver or knife is used to lever the rivet out and then the cover removed.
In the past I drilled out fork locks I didn't have a key for, but now I just hit them with a punch and large hammer. That breaks off the "tab" that retains it and the whole lock then pulls right out.

Thanks Jim and Charlie, I'll see how i get on, Warwick :)

The project stalled for a while, the original flywheel and ring gear were mailed off to be lightened, unfortunately some 5 weeks later and the parts have failed to show up at the shop I mailed them to, have to assume the original flywheel and ring gear are lost in some postal depot, frustrating :angry:
So I decided to go with a RAM clutch, I have one in my V7 Sport and it shifts very easily and clutch pull is a lot easier than on my Eldorado. I put on a couple hundred miles on the V7 Sport today mixed highway and in town and have no qualms using the RAM again.
MG Cycle rushed me a new RAM setup, comes complete with six new high strength bolts and some amusing instructions.
The RAM installation instructions in Italian and English (a poor translation from Italian) say to align the red marks to the white paint marks on the end of the crank.
Glad I didn't remove the paint mark!
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04658_zpsks6wvano.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04658_zpsks6wvano.jpg.html)
The crank has been set to left hand cylinder at TDC compression using a degree wheel and a piston stop
And remarkably the red mark aligns perfectly with the notch in the top left hand of the engine block
(http://i249.photobucket.com/albums/gg217/canuck750/DSC04659_zpstvghfquc.jpg) (http://s249.photobucket.com/user/canuck750/media/DSC04659_zpstvghfquc.jpg.html)
There is another small mark on the RAM body that indicates Left Cylinder TDC in the Transmission inspection hole. I decided to stamp this mark 'L' and 'TDC' and paint a yellow line with a steel engineers square
(http://i249.photobucket.com/albums/gg217/canuck750/DSC04657_zpspteaqvy2.jpg) (http://s249.photobucket.com/user/canuck750/media/DSC04657_zpspteaqvy2.jpg.html)
Then locked the ring gear with the special tool and torqued the cam sprocket nut, the crank and oil pump and folded the lock tab over on the crank nut.
(http://i249.photobucket.com/albums/gg217/canuck750/DSC04665_zpsrx6lt3bj.jpg) (http://s249.photobucket.com/user/canuck750/media/DSC04665_zpsrx6lt3bj.jpg.html)
Installed a new seal on the timing chest cover
(http://i249.photobucket.com/albums/gg217/canuck750/DSC04668_zpsnbgwhadi.jpg) (http://s249.photobucket.com/user/canuck750/media/DSC04668_zpsnbgwhadi.jpg.html)
And a new timing cover gasket, 3 bond on the bottom third of the cover
(http://i249.photobucket.com/albums/gg217/canuck750/DSC04669_zpszqmbvnyh.jpg) (http://s249.photobucket.com/user/canuck750/media/DSC04669_zpszqmbvnyh.jpg.html)
And fitted the tach drive
(http://i249.photobucket.com/albums/gg217/canuck750/DSC04666_zpsw14wqc9e.jpg) (http://s249.photobucket.com/user/canuck750/media/DSC04666_zpsw14wqc9e.jpg.html)
Next to join the transmission and install it in the frame
-
I read a while back a post where a fellow was asking how to move the engine to the bike, I improvise, creeper upside down on a pile of plastic bins on a wheel cart
(http://i249.photobucket.com/albums/gg217/canuck750/DSC04670_zpsylpetrvh.jpg) (http://s249.photobucket.com/user/canuck750/media/DSC04670_zpsylpetrvh.jpg.html)
Wheel the engine over to the bike lift, set the engine stand on the lift and raise the hoist up to match the cart, I have a bad back and I finally try to look after it as I get older
(http://i249.photobucket.com/albums/gg217/canuck750/DSC04671_zpskcxktcbz.jpg) (http://s249.photobucket.com/user/canuck750/media/DSC04671_zpskcxktcbz.jpg.html)
strap it down so I don't tip the whole package over
(http://i249.photobucket.com/albums/gg217/canuck750/DSC04672_zpsnomgcl5o.jpg) (http://s249.photobucket.com/user/canuck750/media/DSC04672_zpsnomgcl5o.jpg.html)
Then join the transmission to the block
(http://i249.photobucket.com/albums/gg217/canuck750/DSC04673_zpsbj9fmlnv.jpg) (http://s249.photobucket.com/user/canuck750/media/DSC04673_zpsbj9fmlnv.jpg.html)
Fit the centre stand and lower frame rails, cad plated bits and pieces
(http://i249.photobucket.com/albums/gg217/canuck750/DSC04674_zpswcomuqbq.jpg) (http://s249.photobucket.com/user/canuck750/media/DSC04674_zpswcomuqbq.jpg.html)
It all goes back together fairly straightforward
(http://i249.photobucket.com/albums/gg217/canuck750/DSC04675_zps8ffdjlk4.jpg) (http://s249.photobucket.com/user/canuck750/media/DSC04675_zps8ffdjlk4.jpg.html)

Then drop the frame a bit and raise the hoist up and after a lot of jiggling and wiggling A meets B
Fitted the swing arm, set the pivot pins and attached the replated foot rests and the new IKON shocks
(http://i249.photobucket.com/albums/gg217/canuck750/DSC04681_zpsihnxt0tb.jpg) (http://s249.photobucket.com/user/canuck750/media/DSC04681_zpsihnxt0tb.jpg.html)

This should be a nice handling bike with the Ikons on the back and the FAC dampers and Progressive springs up front.

New stainless steel cap nuts

I found most of the original hoses at various suppliers from both sides of the Atlantic
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04687_zps8m5ae3kh.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04687_zps8m5ae3kh.jpg.html)
I had the steel brake lines cad plated along with the small hose brackets, rebuilt caliper and resurfaced rotor finish off the rear end
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04689_zpslcldwgtw.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04689_zpslcldwgtw.jpg.html)
I think this hose goes here, forgot to take pictures of this area before I stripped the brake hoses, If I have this routed incorrectly please send me a picture of the correct location
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04690_zps0oxhnhfa.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04690_zps0oxhnhfa.jpg.html)
The rear master cylinder bore was heavily pitted so I opted for a new rear unit

I spent a few minutes polishing the original side covers, I will remove the emblems and grills and compound, touch up and polish the paint, I think they will come out looking pretty good

Got a few things done today, soda blasted the rotor and stator, they both cleaned up real nice, brushed fresh oil on the rotor shaft to 'wet' the seal

This old oil filter wrench works great for holding the rotor while I tighten the rotor bolt

I saved the original horns, just cleaned them and gave them a coat of Tremclad black and some fresh fasteners, the original crash bars polished up real nice and I cad plated the big frame bolts, On the V7 Sport these bolts and the footrest hanger bolts are chrome plated, as they years went buy Moto Guzzi cad plated these parts to cut costs

The chrome plating shop called Friday, parts are finally done and should arrive early this week so I can get the headlight ears and clip-ons installed and then finish the front wheel assembly

I looked over your Stelvio pictures and the various tips (warnings?) on dropping the transmission, daunting job. Old bikes always have glitches to sort, they fall out of tune, etc.. modern bikes, they work great until they break. My R1150RT has been pretty reliable in the past 10 years but on two occasions when it 'broke' it was a major hit and beyond my capability, damn computers, sensors et all.

Well, let's hope this one isn't beyond my abilities.
Getting back to your world, don't you need to update your signature with another entry? :evil:

I got a phone call this evening, the new baby has been loaded and is on its way from the west coast over the mountains to me, it may be here on Thursday, stay tuned....
Meanwhile back in the garage..... a nice bog box of shiny bits fresh from Alberta Plating in Calgary arrived today. These guys do fantastic chrome plating, they are careful to not loose anything and let me know in advance of any issues

I sanded the pits and gouges out of the alternator cover and polished it up to pretty decent shape, not overdone but decent

The cat dragged this home last night, not quite sure what to make of it all, looks decent enough, I need to do some homework, was bought as a 750S, but there are a lot of odd things about it, like the Nieman steering lock that I thought would only be on the 750 S3 and latter, the early type V7 Sport swan necks, a T3 or S3 rear drive, paint is shiny but the stripe pattern is wrong, has Konis on the back, repop mufflers, reop lucas type signals and a 850T headlight, Good news is lots of receipts for engine work, Giladornis etc. It won't take much to return it to correct stock and the frame has to be repainted! It has a strange tail light that I have never seen before on any Guzzi. Switch gear is all off something else and the idiot light bezel has directional indicators, cool. The brembo calipers are newer replacements. And for some reason it has chrome rims and not the correct Borranis.
If only it could talk, I wish I knew its history.
At least the frame is tamped VK1 and the engine serial number appears to be right for a 750S. Bike was imported into Canada from Germany many years ago

I may have to delete this post :cheesy:
Spent a couple hours trying to centre the front wheel, had to machine the wheel spacer and fit a shim to the axle and then shim the calipers, don't know why the calipers were so far out but its all correct now.

Jim,
Just followed through your rebuild story. What a great record. I am rebuilding a second V7 Sport and found your story really inspirational.
It's going to be a spectacular machine again!

Thanks Bill,
We must share the same disease that causes this inexplicable love for 40 year old beautiful Italian motorcycles. Many on this self help forum suffer the same symptoms. Not naming names but each of you with a terminal case of Guzzi-itis know of whom I speak. :laugh:
But what's not to love about perfection?
Post some pics of your Sports we would all love to see them.

Great photo and story line, Jim. Will definitely be referencing it as I get into my (G5) engine and tranny. But where the HELL is the Blue Tool Store??

I took apart the light switches and cleaned and lubricated them, fed them through the clips-ons, nice detail on Guzzi's part to hide the wiring in the bars just like the Japanese did in the 60's, then installed new PVC sheathing

Jim,
if I ever thought about riding my 750s out to Edmonton just to say hello, Ive changed my mind. When Im riding it, I think its perfect. When I see yours it looks like a barn find, prime for your tender (if a bit fanatical) attentions.
Better stay away.

I would love to host you, ride out any time, my shop is always open :grin:

These replacement idle screw springs are too long, I found that on my Eldo the idle screw would not turn in far enough due to the length of the spring, I cut two coils off them and then I get full adjustment of the screw

Thought I would throw this out there, I was not able to find the original left front brake hose and at a vintage bike club meeting a guy mentioned he took his old brake hoses to a local parts store (Gregg Distributors in Canada) and they made him new hoses while he waited.
So I took the hose I needed and the other four used ones and paid Gregg's a visit. In a coupe hours they had made me the hose I needed and five more to use on the Le Mans MK I I am going to rebuild. Worked out to about $40.00 a hose with tax.

I have bought new braided hoses for other bikes and used the DIY kits on my Eldo but for the S3 and the Le Mans I want to keep it as stock as possible. The round banjo ends are not like the factory originals but the rest of the fittings look pretty darn good.
HMB sells the replacement steel lines for the front and rear caliper to rubber hose, including the long steel line that connects the left front brake hose to the rear splitter on the frame.

Time to install the wire harness, I ordered a complete main harness and the sub harness's from Gregory Bender, this is the third set I have gotten from Gregory, his workmanship and attention to detail is amazing. Every connector, wire colour and gauge are exactly as the original and each piece comes in a plastic bag labelled. If you are restoring a Guzzi, Loopframe or Tonti you must get a hold of one of these kits.

The exhaust collars came back from the coaters today with a lovely ceramic semi gloss black finish.

The original Silentium mufflers took a lot of work to get them presentable, not 100% concourse but pretty decent and these cut off edge (not rolled like the repops) are correct for the S3
The collars fitted

Originally I didn't like the black Silentiums preferring the chrome pipes of the V7 Sport, I am starting to like this look more

I removed the emblem and plastic grills from the right hand side cover and went over the surface with a mild rubbing compound to get the dirt out of the paint surface then a very fine polishing compound over all surfaces
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04791_zpsw7b3aqyy.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04791_zpsw7b3aqyy.jpg.html)

Then I cleaned the plastic grill with acetone and a clean rag, keep wetting a clean section of the rag to get the part cleaned
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04794_zpsa52ynjju.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04794_zpsa52ynjju.jpg.html)
Now for the hold your breath part - soak the side cover in metal etch acid to get the rust out, it should not attack well bonded paint
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04795_zpsfh0wmyit.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04795_zpsfh0wmyit.jpg.html)
Then take the plunge, leaving this rust on will eventually allow the part to be destroyed
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04796_zpsqnty3nld.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04796_zpsqnty3nld.jpg.html)
Take some XXX steel wool in a pair of vice grips and gently rub over the rust
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04798_zpsduzvfeld.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04798_zpsduzvfeld.jpg.html)
When the rust is dissolved wash the part with warm soapy water and thoroughly dry the part. It should come out like this
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04804_zpszs0noypp.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04804_zpszs0noypp.jpg.html)
To preserve the inside of the cover I then use Tremclad black, brushed on liberally
(http://i249.photobucket.com/albums/gg217/canuck750/Moto%20Guzzi%20750%20S3/DSC04805_zpstidabkfp.jpg) (http://s249.photobucket.com/user/canuck750/media/Moto%20Guzzi%20750%20S3/DSC04805_zpstidabkfp.jpg.html)

Then to touch up the outside, let it dry
When its dry I will sand the other side with 2000 grit and then polish it again and then give it a couple coats of paste wax,
the gas tank is next

Thanks, its just like building a big plastic model, with a little bit more fiddling :wink:
I feel a 'responsibility' to preserve a bike as rare as this to its original build state as much as is possible. Somewhere down the road, perhaps 40 years from now, another guy or gal may have to restore it again and it would be nice to know they had an original platform to maintain for history's sake.
PS. Chuck, you are right about rust never sleeping but perhaps I can get it to take a nap :rolleyes: I hate rust even when it's called 'patina'

I fool with antique airplanes. The original designers never dreamed that their creation would still be in service after 90 or so years. :) Repair, Restore, maintain original as best you can on an antique.. (thumbs up emoticon) Attaboy..

90 year airplanes! amazing, you are operating under a whole other level of diligence, if the engine in a 90 year plane quits or some critical airframe component lets go someone could die, If I screw up a bike restoration the probable worst case is the buyer will just want to kill me.

I'm amazed at examples like the DC3, which first took to the air in 1935, and is still in commercial use 80 years later!
-
Maybe I missed it, but did you have the exhaust ceramic coated also? If so, is that an expensive proposition?

Yep all ceramic satin black, two mufflers and two clamps about $200.00.
I think that is a very good deal for what is involved, they bead blast them inside and out, etch them and then ceramic coat and bake.

Up north of here, well way north actually, in Yellowknife there is a whole fleet of DC3 and DC4s in service. A couple years back I was doing some work at the Yellowknife airport when a big old DC3 goes lumbering by, I grab my camera and run out of the hanger to get a picture. The airport manager I was with seemed oblivious. I exclaimed how amazing that was. The manager taps me on the shoulder to turn me around to face the opposite direction and there was a line up of 3's and 4's. Then a few seconds later a DC4 fires up and chugs down the taxi way like a steam locomotive belching out thick black exhaust as it runs up to speed. A site and sound I will probably always remember!

I printed out all of the pictures I took during the disassembly and then checked over where I had routed the cables and wires, lots of little stuff to correct
I had the fuse box upside down, original picture

I read an excellent article on Guzzi electronics 'Chasing the Circuit' that Kiwi Roy kindly sent to me, reinforced the importance of a good connection to the frame so I got out the little air sander and cleaned off the ground points and dabbed them with dialectric grease

And the throttle cables climb up over the frame rails here - I wrapped the frame with black tape like the Factory did where the steel brake line can contact the frame cross rail and I also wrapped the frame where if taking of the left carb cap screw the frame gets rubbed

I needed a cap for a coil once and used the ones that come on an NGK plug wire splicer. Wrong color and shape, but sometimes you do what you gotta' do.

I got serious with the paint detailing this weekend and started on the original side covers and gas tank by 1st removing the emblems and the sprung clips that retain them. I saw an episode of Wheeler / Dealer where they take a vintage Porsche in to a detail shop where they colour sand and power polish the original paint to pretty amazing results. The process is to begin with a wax remover and cleaner, then a wet block sand with 1500 frit followed by 2000 wet and then a power polish.
Here the tank has had the emblems removed and wax stripped. After the sanding is done I touch up the bare metal with a detail brush and some universal black touch up, same for the side panels.

The original shape of the side covers, heavy oxidation of the paint surface, stained and chipped and the plastic louvers are milky coloured

The detailed originals, I mixed up red and orange model paint until I got what was a close match, trial and error, when the touch up dried I shot the side covers only with a light 2 part clear urethane and once dry wet sanded about 90% of the clear off and re-polished the covers. There were so many chips in the side covers that the clear top coat will seal the repairs and by wet sanding level the surface.

This is the tank in its 'original' condition

For the tank I just did some minor touch ups and power polished it with a very fine paste and then hand rubbed it down with a sealer glaze. I did repaint the tunnel and clear coated it.

40 year old paint looks pretty damn good if I may so myself

There are still minor nicks and scratches but I am really glad I did not repaint the tank and panels.

Wow, looks fantastic!!! Good work!

Great job , Jim!. BTW, is the seat one of those new repops with the metal base as per the ones available from MG Cycle?. I was having the same issue with the front of the seat compressing on the back of the tank. Then again the Stucchi replica of the old Gaman did the same thing and I had to trim it as well. I got one of the Coil end caps , PM me with info and I will pop one in the mail

Yes the seat is a new Stuchi replica with the metal base, good quality, lousy fit! I will need to take the seat to an upholstery shop to get the foam trimmed down and the cover reformed.

"40 year old paint looks pretty damn good"
Yes :grin:

Yep all ceramic satin black, two mufflers and two clamps about $200.00.
I think that is a very good deal for what is involved, they bead blast them inside and out, etch them and then ceramic coat and bake.
Cheers
Jim
Perfect, thanks. Going to go that route this winter. :thumb:

I bought a pair of the original Aprilia signal light on German Ebay a year ago, these were listed as NOS. They looked beautiful, great chrome, clear plastic lens and shiny screws, I never looked real close. Unfortunately the female threads were stripped on both of them and the hollow threaded stud is imperial. not metric! NOS?? maybe, perhaps some dumb ass just fitted some studs off a Lucas light and wrecked them and they ended up on Ebay.

All metal pieces other than the orange plastic lens, sprung lamp holders, very high quality signal lights, you won't find this quality of parts on new bikes

The 750S3 was arguably the last of the high end spec bikes Guzzi made before DeTomasso lowered the spec across the board.

Spectacular work Jim! I'm in awe.

Thanks Cam, I wanted to get it running by August and providing International Post from Germany comes through I think I will make it. As much as I try to plan in advance of what I will need to keep going there is always some obscure part I need to finish a piece off.
Our local chapter of the Canadian Vintage Motorcycle Group is hosting a summer in the park vintage display this Saturday, I was hoping I could of got the S3 down to the park as a non runner but that won't happen this year. We had a great turn out last September of 100+ bikes from a 1911 Harley single to bikes from the British, European and Japanese on display. I am doing my part to wave the Italian flag :laugh:

The chrome shop sent me the last of the platting, they did a nice job on the pot metal Aprilia signal light castings, many shops won't touch pot metal

Unfortunately they did not protect the fine 3mm female threads in the cast body, it took me over two hours to carefully drill tiny holes and tap the threads back

Not much left to do; fit the distributor, the clutch cable, some wire connections and then it will be time to fire it up,
-
The post office returned my long lost flywheel, it never made it to Ed Milch's shop and it took over 4 months to find its way back.
Now I can transfer the timing marks to the RAN clutch.
Guzziology says to install the distributor at the static timing mark, second mark above D.
My V7 Sports had a static timing mark very close to the D.
Here are pictures of the flywheel, the red line is the D. IS the 2nd yellow line the correct static mark?

The red line is the first line or TDC, the first yellow line is static and the second yellow line is full advance.

Its finally done, I rolled the S3 off the lift this morning and put it on the trailer, its in storage in another garage waiting to show it next weekend in the International Motorcycle show in town.
I filled the tank with Evaporust for a week and got the inside spotless. No gas yet, I will fire it up after the show.

What are your plans for this one? Have you decided how much of the bike is S?
I really enjoy your posts and appreciate all of the excellent work you do. It is so easy to sometimes say "good enough" when knee deep in a project.

Thanks for the kind words fellas,
For the 750S I plan on restoring it to full original spec. I have found all of the parts I need to make it correct. I have rebuilt a pair of the correct Borrani wheels, sourced a rebuilt final drive from an Eldorado, found a correct pair of swan necks, head light, signal lights etc... It will get the full Gregory Bender wiring harness replacement a CEV fuse box and all the other little parts needed. The engine was supposedly rebuilt with a new crank, bearings and Giladorni kits (we shall see?), forks look good, calipers are new, the list goes on. I have a fresh pair of 750S tool boxes and a gas tank already painted in the green scheme. The project will get going as time allows.
Cheers

I spoke with Fast Industries (the Canadian branch of Millennium) in Manitoba, after a short discussion I mailed off the original cylinders and two NOS pistons, they will plate the bores and size them to the pistons. I also sent them the heads, new guides, valves and springs plus the retainers, spring shims and caps, they will grind the valve seats and shim the valve springs, and I asked them to deck the heads while they are in there.
Jim...
When Millennium sized the bore to the pistons what clearance did they target?
I just boxed up my V7 Sport pistons and cylinders to send off today to send off for replating with NiSiC.
I think a reasonable value is 0.0015 - 0.002 in based on the following below. The LM4 is the only NiSiC bore for Guzzi that I checked out but I also found some air cooled cars (Porsches) that use this range with NiSiC.
I went into some factory manuals (thanks to Greg Benders fantastic web site) to do some research into piston to bore clearances and wanted to share what I found.
V7 Sport chrome bore
Cylinder 82.500-82.006 Min 36 um ~ 1.5
Piston 82.458-82.464 Max 48 um ~ 2.0
850 T chrome bore (also LeMans II)
Cylinder 83.000-83.006 Min 26 um ~ 1.0
Piston 82.968-82.974 Max 38 um ~ 1.5
850 LeMans CI sleeve
Cylinder 83.000-83.009 Min 55 um ~ 2.0
Piston 82.936-82.945 Max 73 um ~ 3.0
G5 CI sleeve
Cylinder 88.000-88.009 Min 71 um ~ 3.0
Piston 87.920-87.929 Max 89 um ~ 3.5
LeMan IV - NiSiC Cali 1000 the same
Cylinder 88.000-88.006 Min 26 um ~ 1.0
Piston 87.968-87.974 Max 38 um ~ 1.5
I need to nail down a value this week.

I need to nail down a value this week.
Not sure, I sent them a new pair of pistons and rings I got from Harper's and they sized the plating to match.
Cheers

Jim,
I just got done spending a good part of my Sunday afternoon and evening going through the whole tread. Awesome effort and the end result is stunning. If I understood correctly, you were showing the bike in a local show... I wish I could attend to see it in person.
This thread is better than pretty much any other Sunday entertainment I could have come up with!
I look forward to your next adventure.

Once again a nice job Jim .......Congratz

Thanks Raymond!
I have really enjoyed bringing this fine bike back to full health and I even controlled my urge to not repaint the tank and side covers.
On to the 750S project......

I have worked out a deal to sell the S3 back to its original owner who will give it the love and care it needs but more importantly ride it regularly!
I finished the rebuild over a year ago but today for the 1st time attempted to fire it up. I set the point gap, set static timing, fresh oil, gas, charged a battery. Pulled up the choke levers, turned on the gas and with fingers crossed hit the start button, a couple revolutions of the starter motor and VAROOM! it fired right up and sounds great. I ran it or a couple minutes, let it cool down and checked all the oil and fuel lines, no leaks. Started it again and let it run for 10 minutes with a big shop fan keeping the motor cool. Drained the oil, replaced the oil filter and tomorrow I will re-torque the heads and set the valve clearance and set the timing with a strobe.
It feels so damn satisfying when a rebuild fires up and runs smooth!

Hi, Jim.
Luca told me last weekend that you guys had reached an agreement, and he was so excited about the bike coming home. I'm really glad it worked out this way!
Well done!

One of those things that was meant to be.
I had to resolve an electrical gremlin last week, duff starter button, I had a brand new one in my stash, once fitted all electrical problems resolved, otherwise its like it came out of a coma after major reconstructive surgery.
I hope Luca rides the wheels off it, I am looking forward to his comparison of the before and after now that it has Ikon shocks, FAC damper, progressive springs, new tires and brakes and the B10 cam. :evil:

Sounds good! Will be interested to hear what he says, as well, and maybe we can compare will my 950S tribute if I get it done. :afro:
Hope it gets here soon so I can see it. Planning to move back West someone soon. Maybe we'll take the northern route and stop in to check out your collection. :grin:
Cheers,
Shaun
