Hello,

I am assembling the clutch on my B20.
I have gotten hold of a new release bearing and the shim and spacer, part #32 and # 42 in the enclosed diagram.
Part #32 is too big, and wont fit inside the housing.
Does anyone know the correct specifications for this part?
I would guess the outside diameter should be the same as part #42, but perhaps the inside diameter should be a little bigger?
Perhaps someone has a spare they could measure, or even better: sell?😍
All help much apreciated.

Torstein

Just to follow up on the recent emails I sent you Torstein.
Your TAV 27 drawing above refers to 4th series B20 ( and also I think B12) clutches.
There is an earlier version of Aurelia clutch assembly drawing TAV26 which is for B10, B21 and probably B20 3rd series and earlier where there is no component #32 or #42. The later modifications are presumably due to increased power?
Hope this helps.
Chris

Thank you for the follow up .
Interesting! Yes, some sort of modification to deal with the increase of power I guess.
