Great day @ WAZOO....10/12/16

[QB93Z]

It was a great day indeed. Bob's 1993 Polo Green LT1 was making a strange noise from the clutch when the car was at operating temperature and the clutch was fully depressed. With the clutch partially depressed (~75%) the clutch worked properly and the transmission could be shifted.

This C4 Corvette has 210,000 miles on it and runs well. All of the clutch and associated components (including the pivot stud) were replaced about 50,000 miles ago.

After disassembly, we found that the noise was coming from the clutch fork "rubbing" against the inside rim of the clutch plate. The clutch fork was making contact with the clutch because the pivot stud had slightly backed out of its mounting hole.

This is an LT1 car so the bell housing looks a little different than our LT5. Here is the disassembled fork and pivot stud:



Here is the slight mark where the rubbing occurred:




Here is the pivot stud:



Many thanks to all of the WAZOO guys who helped make this repair, it was definitely a group effort. Special thanks to Phil for his expertise and assistance.
