That usually happens from sitting on something cold and hard and flat, like a BMW seat.

And being "of a certain age".

I now have in my possession mailed from Cycle Works USA, 1 shimming plate for um, shimming, and 2 parallel bars for measuring the depth of the bearing pockets in the cover.
The parallels are 6" long. I can understand using a long bar across the cover to give a more accurate measurement of the bearing pocket depths, because the bars will pick up any distortion in the cover.
I'm not quite sure why two parallels are used?
Anyone know?

I can't wait to go fishing this weekend fix my tranny.
Did I say I was going fishing this weekend?

If you lay the two parallels across the bearing pocket, you can measure down between them with the pokey end of your micrometer and get as acurate measurement as if you used one of these fancy dohickeys:



Or you could use them to measure your fish.

Excellent Garnet, thanks. I have a dohickey! It ain't mine and it's in thou, but I have one.

As for the fish, I only have two 6" parallels. I'll need at least four. Or five.
Late tomorrow afternoon should be good for a trout with an approaching weather change.

I've never seen micrometers with pokey ends. I have calipers with pokey ends, is that what you meant to say?

The Major's just trying to keep his pokey ends straight here....

No, I still have drum brakes on this bike.

After re-measuring everything, I've come to the following conclusions.

Lay shaft needs .95 shim
Input shaft needs .876 shim
Output shaft needs .935 shim

Gasket included in calculations.

Well the cover is back on, and the tranny is recovering in post op.
I should be able to visit the tranny in half an hour when everything cools down.
The cover went back on with a good amount of heat.....sizzled spit seems to be the go. The cover made contact with the gasket all the way round and wasn't sitting half an inch too high. So far so god.
Shafts spin reasonably easy.

Regards using solder, the shim sizes I needed relieved a lot of concern about the cover being bowed if using 1mm solder.
.95, .876 and .935mm

Out of interest prior to installing shims, I stacked all of the original shims and measured them @ 1.95mm
The total of my new shim calculations amounted to 2.76mm
I did read somewhere (ADV?) that differences in thickness between a stock 5th gear and the taller 5th gear caused problems when the shims were not remeasured after installing lower first and taller 5th.

Did I get it all correct? Guess I'll find out.

Struth! I'm not that quick.
Ashly, I'm whipping the cover off again. Not happy with it. Input shaft should be easier to turn as is evident when I undo all the cover bolts. Bit tight there somewhere....
Oh well. I'll get it.
