Excessive wear on diaphragm tips
- Clutch diaphragm fingers or levers are uneven
- Diaphragm fouled on clutch disc
- Excessive wear on diaphragm tips
- Hold down bolts still in cover assembly
- Burst pressure plate casting
- Interference with the other part
- Abnormal sound with foot off clutch pedal (metal squeaking sound). Sound disappears with light pressure or full depression of the clutch pedal is applied.
Cause
1) Misalignment between the axis of release bearing and clutch cover causes this problem. Wear on the fulcrum inside of clutch cover along with the wear on lever tips makes less pressure plate lift, results in difficult to disengage gear.
2) Improper direction of release bearing causes one of abnormal wear.
Solution
1) Replace the deteriorated bearing or bush parts. Reinstall a transmission after removal of contamination or scratch on the mating surface of bell housing. Replace the deteriorated release bearing and front cover.
2) Install a release bearing in correct direction.
