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.

Its all good, I picked up three bags of Soda media but based on the snow storm from sending a bag into lala land last time (outside) I need to make some from of low tech blasting cabinet.
The top is going to be a 1200 x 600 x 12 mm glass swimming pool fence panel, $57 at Bunnings.
