Clutch Cables
There are two basic problems with clutch cables:
1. They stretch, thereby causing a "No Release" condition.
(Failure to move the fingers 1/2")
2. They bind causing hard pedal, incomplete release or incomplete
engagement of the clutch cover, resulting in slippage and then
burnout of the clutch disc.
A common cause of binding is dirt or foreign matter getting between
the cable and it's housing. This condition can be determined by visual
inspection and checking for free movement of the cable.
A less obvious condition can occur which is sometimes
difficult to diagnose. The removal of ground straps from the engine
to the firewall or engine to frame forces the clutch cable to become
the grounding source. When this occurs the cable becomes heated up
beyond its limits. It then binds in its housing.
Result will be possible hard pedal and/or most certainly incomplete
release of the fork/throwout bearing from the fingers of the clutch
cover. Incomplete release leads to short life of the clutch disc.
It has the same effect as driving with the clutch pedal partially depressed.
