Cause

1) When engine torque is higher than clutch torque, this misapplication causes springs to deteriorate.
2) Misalignment between engine crank shaft and transmission main drive shaft causes this problem during installation of transmission.

Solution

1) Choose and fit appropriate EXEDY clutch to suit the application.
2) Reinstall deteriorated pilot bearing or bush parts after removal of contamination or scratch on the mating surface of bell housing.
