Re: Clutch wear test

The test for clutch chatter is whether it chatters or not. It should not, period. If it does, there is a problem. The clutch should engage smoothly and predictably with no grabbing, lurching or chatter.

Clutch chatter can be caused by several problems, including oil on the clutch disc, motor mount problems, linkage problems, a worn, missing, or improperly adjusted anti-chatter damper device, or binding in U joints or in the slip yoke. In some cases, problems with rear springs can cause clutch chatter, and throttle linkage problems can cause clutch chatter.

The commonest clutch chatter cause is wear or bad adjustment in the anti-chatter damper device at the rear of the transmission, and/or a loose or broken motor mount.

Note that many cars have some leakage of oil at the rear main bearing and yet do not have clutch problems, so don't assume some oil dripping from around the engine is necessarily the problem. The shop manuals and perhaps some of the service letters have information on the damper device and on diagnosing various clutch problems.
