Hi Ulrik   

Yes it must have been the same packer.  :laugh:

Yesterday was spent driving down to the city, a new 3 cylinder compressor will arrive today and the electrician will come Thursday to fit a 15 amp outlet direct to the power board so I can soda blast some of the castings. ( I did not want to blast anything if possible)
When I got back I spent a little time on the block off plate for better or worse.

If I had an agenda it would be never be afraid of trying something new and would hope by posting a few pictures someone out there might consider buying a small lathe or mill/drill and having a go themselves.
My trade is boilermaker / welder so far removed from any form of machining but get by. (Thank you for the comments all the same)





I got a set of the VHB slides off eBay (They are reproductions going by the description) and tracking says they arrived in Australia on the 7th so should be here by Friday.

12 pictures in total, I notice I can not see some pictures in other posts without reloading the page.

I forget which year I replaced the universal support bearing but remember it pressed out with no problems.





To press the new one in a mandrel was turned, the spigot in the centre fit the bearing bore, the face was relieved so only the outer race was being pressed.
The OD with clearance so it could press the bearing home without binding in the bore for the bearing and allow the circlip to seat securely.





Same bench but 1000 kms away from the location of the pictures above.
I picked up some bearings for the pivot a week or so back and the trusty chinesium slide hammer removed the cups that were still in place.
A mandrel with a 12 mm deep step and 0.05 mm (0.002") under 40 mm diameter made installing the cups easy.



First the sleeve.





The bigger diameter of the mandrel had been faced in the lathe also so it was used to start and fit the bearing cup flush.
Flip it around to the shouldered side and seat it with a couple of taps.







Same again on the other side.



I like this stuff, very tacky and stays put.



The electrician is here in the morning to install an outlet for the compressor but will pack the bearing inners and fit the seals tomorrow.
I need to finish wall mounting the clothes dryer first, exciting stuff.

All good balvenie.  :thumb:

The eBay VHB slides arrived today.
Original 60 slide on the right, that new slide sure does look like a 40 cutaway and suggests the same thing in a carburetor, side by side.
I will get back to them and might be missing (not seeing) something, code blue is soda blasting for tomorrow.



At least the dryer finally getting elevated got the ultra sonic cleaner off the kitchen counter and into the laundry room.
The wall studs centres / centers wouldn't play the game so a hard wood bearer was needed to mount the top hanger brackets but then the lower legs were short by 23 mm.
Did I mention how handy a small lathe is, hey presto 23 mm extenders for the win.  :laugh:

Here you go then, the swing arm is as about as ready as it will ever be.

The bearing cup installer got a bleed hole so it could be used to seat the seals to avoid any air pressure in that cavity.



I put a little extra grease in there.





Seal in with no drama, it got a wipe of rubber grease as did the OD of the spacer piece.



Maybe there is some secret way to install these but the extra grease was to allow for air pressure, now when the pin is installed that pressure should push some of that extra grease though the bearing to replace any that might be expelled.
I don't expect to look inside here once in stalled in the frame for some time.




Joe (bsanut) got back to me about the eBay VHB slides and said I can send them back, to hard, will machine them into 60 cutaway.
I got a set of the bigger outlet 'torpedo's so wonder if the jetting (including cutaway) is the same (big and small outlet muffler)
Early days but could make any cutaway including slightly richer than a 60.

With all that progress yesterday I thought I better catch up with some other bits that had gathered dust.
As posted a ways back, I had found the final drive ring and pinion to be some what beyond service (Either little to no oil or lack of moly additive perhaps)

Anyway who knows how many years ago I had picked up another complete unit off eBay and the pinion was still in its carrier until after lunch today.
I started off tacking an old drive shaft coupling to the end of a Norton fork stanchion, that and a large 36 mm ring spanner did nothing even with some heat on the nut.
Loctite (and double dimpled nut) I bet.

Next was putting the pinion head between hard wood and nylon plate in the press and with heat again it got the impact gun treatment.
Nothing.

Out came the adjustable speed die grinder with (USA) burr.
Holy cow, this is how much it took and still came off with some effort even though cracked, and yes the Loctite was even under the taper roller bearing.
Any way it came up nice, it is a good OEM set, I heard some of the aftermarket sets are not as good as original parts.
The housing ball bearing carrier was warmed and old bearing pushed out easily.











Subeam final drive.

Great news, a package (from Italy) that does not contain paper weights or some other calamity.
I can't remember which thread I was reading that had a link to new wiring looms but thanks to whoever it was.

The pinion carrier got some new bearings and then a bit of fiddly stuff to while away a few hours.
Working to a half millimeter is normally close enough.



First thing I noticed but standard for any stepped shaft with a fillet was the heavy shims were only beveled on the ID on one side, a check showed installed the right way the shim was flush.



The new bearings were a little tight so the pinion shaft got a very light polish in the lathe and trial fit until they pushed on with moderate force without binding.
A quick look on MG Cycle past orders showed I had got some spare pinion shims last year so hunted them down. (Both of the final drives, original and eBay only had 0.15 mm shims)
With a bit of juggling of tube spacers and shims I got it down to a reliable 0.02 mm (less than 0.001") end float with the nut pulled up.
I don't know how hot these things get and if the pinion carrier housing will grow closing up that end float, I might try and get a little more tomorrow but under 0.05 mm.

I got back this morning to find a package at the door.
Thanks for the heads up Charlie.

It was only the rears showing any real wear and were probably still serviceable but 4 'NOS wheel bearings from Germany.

It's been my experience that pinion bearings should have no play. In automotive applications, they are set up with drag. Moto Guzzi does not give any information on this as far as I can see. I've consulted several people in the automotive differential rebuilding business and some older workshop manuals. I've found that the recommended drag on pinion bearings, whether adjusted by crush sleeve or shims, is 20 to 25 inch pounds with new bearings and 12 to 15 with used ones. Also, torquing the 36 mm nut is important. Again, I can't find a spec for torque, I'm tightening them to 120 ft lbs.

Howdy,
by any chance did you change the main bearings? I am looking for used undersize that I can fit to my crank.

There are plenty of secondhand ones on eBay, maybe the grumpy guy has some.

The bearing flanges out of this bike were junk.
Not very good photo's but they are pocked, I do not know enough about this type of bearing material to know if it was high mileage, chromium off the bore or a combination of the two.




Remember only things retained are.
The engine case / block.
The crankshaft but will have to go second under.
The bare cylinder heads and rocker covers.
The timing chain gears.
The distributor.
The two front engine covers, generator assembly and its mounting bracket.
Any other sundry jewelry.
The rest was junk as was the complete drive line including the transmission output shaft.

I gave the Africa Twin a service yesterday, two new oil filters (DCT) Honda oil and hit the button, to easy, also picked up a set of Continental Trail Attacks to fit later this week.
I think you need one modern bike to stay sane.  :laugh:

The low tech 'sodi blast cabinet is done, just waiting for some gloves to arrive in the mail to finish it completely.

Thanks for the replies.

Things have ground to a halt once again.
After having to pay the return post cost of the broken 949 cylinders back to Germany and then hearing nothing I contacted them to be told they do not have a pair of replacement cylinders to send me.
The 949 pistons are some 35 grams heavier than the stock pistons so the crankshaft will need to be re balanced, I still have the B pistons that came with the broken cylinders but do not want to take the risk (ie Do not trust HMB ) of having the crankshaft ground to M4 under size then having it balanced to the bigger pistons without having the cylinders in hand to suit them.
Maybe there will be some updates later in the month or year.

You won't believe it but five weeks later, nothing, six months and one day after that box of busted parts was posted, nothing.
The order I payed for a month ago that contained a new rear bearing and other needed parts (I figured I could at least get the crankshaft ground) you got it, not shipped.
I guess in another life I pi$$ed off the Moto Guzzi gods it seems.  :laugh:

The months long search for a replacement gearbox or gearbox internals went nowhere so I ended up grabbing the sight unseen 1000SP gearbox off the San Francisco Craigslist after a phone call to the seller.
It should arrive this week and given the risk am hoping for the best, I have some concerns that being 60 next year I might run out of time  :violent1:

The Craglist picture.


With a bit of luck it will be a good one and the internals can go in the original Eldorado case which gets all new bearings.
I will work on something else until then.

I have a couple of Commando's.

I just got off the phone to the USA, the International bank check I posted to pay for that transmission was payed out and then a month later the funds were deducted from the account and the check returned (to the seller).
It seems I have a trans somewhere in the post I haven't payed for it !

Other than that things are going well.
HMB will send me the one cylinder they have in stock , the other one availability is unknown at this stage........

You won't believe it, there is a drama.  :laugh: :grin:
A visit to my bank has revealed a hiccup (luckily I had taken a photo of the cheque / check) so am waiting for an update before Interpol / FBI or similar start looking for me.


It all started when I read this thread many years ago, if only I had known..  :laugh: :laugh:

I picked up and posted another bank cheque/check this afternoon, this one had the right encoding etc and should be in the USA mid week.
Curiosity got the better of me, I cleaned all the gunk off the case in kerosene, dried it off and removed the rear cover then pulled the two gear cluster shafts/gears.
Obviously I couldn't see the inner surfaces where the needle rollers run but the gears and dogs (put my reading glasses on) look very nice, I don't think you would find better.
No galling, no pitting, no chips and all of the dogs are very nice.

It does have the later roller type thrust bearing (steel/bronze?/steel thrust in the Eldo trans) but nothing is jumping out to suggest it will not go as a complete unit into the 1973 trans case.
I have a complete set of HMB Guzzi bearings for the original case (I will use the double row ball units they supplied) new needle rollers and other sundries.
  :grin:
