The best part of a rebuild for me is assembling the engine and gearbox. All those nice clean parts laid out and methodically installed. I've got a LeMans to refurb for a friend this winter but sadly it needs no engine work so I'll have to just watch this instead!

Sorting out bits and pieces that need to be refinished. Parts to be zinc plated:



Painted black:


Chromed:


Wrinkle black:


Okay, back to engine assembly. Alternator rotor and stator on:


Oil pressure sender.


Lifters inserted into their bores:


Base gasket and o-rings on the short studs.


Pistons and cylinder installed.


Uh oh. The head gaskets I pulled from stock are for the later engines, pushrod holes are farther away from the bore. Need to order the correct ones.

Almost, but not quite. There are a few items (all chrome plated) that will be left "as-is", not rechromed. Headlight shell and rim, headpipes, crossover, clip-ons, etc. The customer is already into this bike for considerably more than market value, so we're trying to save a few $$. If in the future he wants to do all of the chrome, it's fairly easy to remove.

A little more progress today. Heads retorqued, pushrod and rockers installed.







Sorting hardware for the intake manifolds and "distributor".




Rocker covers cleaned and set in place temporarily.

A little progress.

Stripped and repainted the breather box.




Rocker covers and manifolds have been media blasted. 


I had already drilled and tapped them (on the underside) for vacuum ports.


Installed. 




Slipped the breather box on temporarily.



Working on the distributor. Disassembled.


The main body cleaned and reassembled with new o-rings.

That high volume low pressure glass bead process you use sure leaves a nice finish, very 'stock' appearance. I think the vapour blast leaves more of a shine but your finish is probably closer to the natural fresh casting.

It sure does, especially when they've just put fresh media in. These are the parts for my V700:







I took them moderately dirty, slightly corroded bits and for $140 I got shiny, clean parts back. Jamie, at the machine shop, is meticulous in his prep: all of the threaded holes are plugged, critical areas masked off, parts cleaned before and twice after. Makes no sense for me to do it myself.

More done today, still not as much as I'd hoped.

Painted the coil mounting bands...



...and the coils.


Prepped the shift and brake shaft supports for paint, but ran out of paint on the coils. Need to get some more.


Put the distributor hardware on. 


New springs are ordered, more progress here will have to wait until they arrive. 


cleaned and installed the flywheel...


...pressure plate is next...


...compressed with a tool made from an old clutch hub.


First friction plate slipped on...


...then the intermediate plate...


...second friction plate...


...and finally the cover/ring gear.

The support plates are painted.



And all of the wrinkle black pieces have returned from the powdercoater.




Distributor springs, condensers and the electronic voltage regulator have arrived from MG Cycle. 


Springs installed.


Same with the condensers.

I'd be worried that such a beautiful job would be spoilt by some manky chrome. Unlike my Ambassador, that is getting there, will all look a bit manky!

Points plate back on, static timing set.



Disassembled the transmission. The output shaft nut put up quite a fight - I think it was (red) Loctited into place.


Bearings feel good and gears all look excellent. 




This bearing isn't supposed to fall out out of the case though. 


I've never seen a shift return spring like this one. Looks like some sort of generic spring.

Heating the case and rear cover to remove the bearings.







While most of the transmission looks great, there are some issues. The driven gear of the speedometer drive is a bit boogered up. I'm guessing that the missing hardened washer was in there being ground to pieces.




You can see there's damage to the bearing cage as well.




The rear cover shows some minor damage too.

The parts I sent out to be zinc plated have returned. Parker Metal Finishing did an excellent job.





I snuck in a few Loop parts too.


While the transmission cases are off being cleaned, I'm starting on the chassis. Removing powder from ground areas and chasing threads. 




Installed the outer races of the steering head bearings... 


...and reattached the VIN plate.


Working on the voltage regulator and diode board next. 


Diode board needs a good cleaning, before assembly.

Really liking the zinc plating. I don't recall coming across anyone else doing that during their restorations that I've seen in the past few years. What's the process? Does the zinc add thickness? Looking great as usual!

Jim/canuck750 has parts zinc-plated too. I'm only redoing what was already there - Guzzi zinc-plated all of these bits originally. Done correctly, it doesn't add thickness. Parker has done it right, I can thread nuts onto the bolts without having to chase the threads. Previous vendors got it a bit too thick.

The process on my end is degrease and derust everything, plus I went over all of it with the wire wheel of my bench grinder. What Parker does? I'm guessing a stripping bath, rinse, plate, dry, box for shipment. http://www.parkermetalfinishing.com/our-services/

Beautiful plating work there Charlie, it's down the prep work you do to get that nice a finish.

Like you I strip all zinc plated parts, wire wheel, acid wash, rinse and send the whole lot off, washers, nuts, bolts, pins, axles etc... I believe the original fasteners are better quality than anything new.

Jumping ahead a bit. Diode board attached to the brackets, charging harness hooked up, assembly installed. Terminal block mounted.





Made a new ground wire to go between the diode board and frame.


Mounted the coils. Couldn't quite finish, ran out of the rubber cushioning washers.

The rubber washers arrived from McMaster-Carr, so I finished up the coil mounting.



Installed the lower yoke and rubber tank bumpers. 


Removed the powdercoating from the pivot areas and loosely assembled the sidestand. 


Same with the centerstand. Missing one spring.


Chased the threads in the top clamp and installed new hardware. 


Installed the rubber tank mounts.



Assembled the footpegs to the brackets. Missing a jam nut. I know I sent four to be replated, only three came back.  :angry:


Applied the decal and installed the warning lights.

More "busy work" while I await the return of the transmission case and cover.

Cleaned the gauges and their rubber boots, loosely assembled the instrument cluster.







The headlight bucket was in surprisingly good condition to start with, looked even better with a little cleaning.







It even still has the original CEV 45/40 watt sealed beam.




All cleaned up, new hardware, ready to go back on.
