Common Pilot Bearing Issues/Failures
- When a pilot bearing fails, it does not allow the flywheel and input shaft to turn at different speeds.
- Noisy when clutch is released.
- Does not allow the input shaft to slow or stop adequately to change gears.
- Can cause excessive wear on input shaft bearing retainer because the input shaft is still turning while clutch brake is squeezed against the input shaft bearing retainer.
