All clutch troubles, except adjustments, require partial engine disassembly to identify solve the problem.


1. Slippage This is most noticeable whet accelerating in a high gear at relatively low speed. To check slippage, shift to second gear release the clutch as if riding off. If the clutch is good, the engine will slow and stall. If clutch slips, continued engine speed will give it away. Slippage results from insufficient clutch lever free play, worn discs or pressure plate weak springs.


2.  Drag or failure to release This trouble usually causes difficult shifting and gear clash, especially when downshifting. The cause may be excessive clutch lever free play, warped or bent pressure plate or clutch disc, or broken or loose linings.


3.  Chatter or grubbing Check for worn or warped plates.

            NOTE: Clutch wear is accelerated if the transmission is habitually left in gear with the clutch disengaged while waiting for long-duration traffic lights. Instead, shift the transmission to neutral and release the clutch until the cross-traffic amber light indicates that the light is about to change. In addition to reducing clutch wear, a measure of safety is gain­ed in that it precludes a cable failure, most certain to occur when the clutch lever is pulled in.





Transmission problems are usually indicated by one or more of the following symptoms:


a. Difficulty shifting gears


b. Gear clash when downshifting


c. Slipping out of gear


d. Excessive noise in neutral


e. Excessive noise in gear


   Transmission symptoms are sometimes hard to distinguish from clutch symptoms. Be sure that clutch is not causing the trouble before working on the transmission.
