Explain please..:)
Turbo Mini Forums

Still not 100% sure in why you need 1 thou tolerance for the 3rd motion bearing ? could someone explain in detail on why you need this please.
As some might know, i check and there was 0 thou. I just put in my old 5 thou just too see.
Then i checked and there is no Gap whatsoever between the
C- retainer and outter bearing case. its up tight against it.
Is this part meant to have the tolerance overule? .

I know you check from where the 3 bolts are to see what thou you get, then add a thou, and u get the right shim

For some reason, i thought the whole bearing moves around.
this is why i thought u need the tolerance on the outer bearing.
Durr i know..
Im still going to try an old C-retainer if someone as one spare.
But for now, i need to know clear on why.
Yes im a pain, but i like to know how things work..
Cheers :)

Have a look at the old post. If you get this back to the old post you might get the info you need

Sure, the bearing moves. think about what it is you're clamping - it;s not the bearing, it's the locating ring around the bearing. There is still axial movement between the bearing and ring.
All you're doing is getting the axial movement to a minimum by shimming this.

Personally - I think you're going a little overboard. I always have a few retainers, a selection of shims, and get this done in under 5 minutes.

Exactly how much 'nip' are you putting on the bolts to determine thou? You should be putting 2-4 lb ft on there - nothing more, nothing less.

If you have 1 thou, at this point, then try tapping it into place throuigh the hole in the end of the trans to see if it'll seat any better. If it won't, then make the descision yourself. Either try tightening the bolts to 10lb ft and see if it pullls in (i suspect it will) and leave it at that, or juggle things around and leave it with 2 thou clear so the retainer is clamped tight but the locating ring on the bearing is theroetically allowed 2-thou of movement.

In reality - that isn't going to ruin or wreck your transmission.
Just get it built and don't get too concerned about it.
