Clutch Chatter

The center collar portion is definitely some type of non-ferrous material, possibly some type of plastic. The actual bearing portion is steel.

So this is the proper way for the bearing to be installed?



To be perfectly honest, it may have been that way when it was in the car.....in the pictures I posted yesterday, I may have reinstalled it with the tangs on the outside of the collar. It has been over 30 years since I have installed a throwout bearing on a GM product, so I really don't remember how I used to do it.

One other thing I noticed today, the collar portion is not perfectly concentric with the bearing portion...





And finally, to address William's post about the motor mounts....for at least 6 years prior to last October, this car had a different clutch and transmission in it - with the same motor mounts that are in it now - and there was no chattering at that time. It was an excellent and interesting point to bring up, but I think it does not apply to this car.

Thanks so much for all replies thus far!
