Damaged torsion springs
- Contact mark on the teeth of spline and the end of hub
- Burrs at the end of hub due to uneven wear on the spline teeth
- Damaged torsion springs
- Damaged facing material
- Oily facings
- Broken facings
- Wear out on teeth of spline / Cushion spring steel segments separated from hub area
- Rust on the teeth of spline hub
- Unable to install the clutch disc to the main drive shaft
- Dropout of torsion spring/wear out of stop pin
- Hit mark to spline teeth and end surface. Crack to clutch plate.
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.
