M4A2 Sherman clutch shim question

[Malcolm Towrie]

Fantastic info, Colin! Thank you very much.

You’re right, all the info you gave me clearly states that, with the thickness of frictions I have, there should be two 1/32” shims per bolt. That’s what I’ll install. Mind you, I’ll have to make 12 new shims, which will be a pain. Wonder how much laser or water jet cutting costs??

And the Detroit manual gave some interesting info. The shims aren’t to control the diaphragm spring pressure on the pressure plate, as I had assumed, but to keep the release bearing in its working range. I assume that allows the bearing to release enough to allow the spring to apply full pressure and to pull spring back enough to let friction plate spin freely.

Thanks again. I love MLU.
