Q2 diff - bearings preload

Hello guys, I'm gonna fit the Q2 diff into my bella in the next few weeks. I've got all the stuff from the EB Spares and going to do that on my own. What I don't have is any transmission service manual for 6-speed g'boxes. I've got full service manual for GTV (both German and English ones) but the chapter about transmission is not really detailed so for example the value for a preload of the diff bearings is missing. Does anyone knows what preload in mm to set there? Cheers

Re: Q2 diff - bearings preload

huh? Theres a shim that strctly speaking you should check to make sure its the right thickness but otherwise, you just press the bearings on to the diff and bung it in.

There is a shim kit that goes with the q2 diff.

I've got the shim kit as well. But it doesn't tell me which shim to use (to preload bearings). As I'm going to use new bearings, I have to shim it again. For C503 g'boxes preload 0.12 mm was recommended (Alfa Romeo 155 & 164 manuals). But can't find any value for C530 gearbox...
