ZF Release bearing question
Can you change the Release Bearing (throw out bearing) with the Pressure Plate on the car?
I will find out for sure on Friday but, wondered if anyone had done this.
TIA

I think you can. It is only held in by a spring ring around its perimeter if I recall. If not, it is only a couple of bolts to remove since the tranny is already out.
Can you even buy just the TO Bearing? I had to buy the entire pressure plate - glad I did since the springs were pretty weak.

Yes you can buy the release bearing seperatly.
I just wonderd if the clamp load on the Pressure Plate as it is clamped down , interferes with the removal of the bearing.

ALso, the TOB for 89-93 is 3.175 ID and the 94-96 TOB is 3.110 ID
Also, the 94-96 has a plastic sleeve in the TOB ID that makes contact with the tranny tube that is over the input shaft.The 89-93 is all metal in the ID.

When I bought a new pressure plate for my 91 from GM it came with the late style bearing and I had to change it. The early bearing is available from GM part # 10203567. Just remember that the bearing lever ball stud is a left hand thread (turn it to the right to loosen) looking at the face of the bell housing. Hope this helps
