The flywheel is a large, heavy metal disk that mounts on the rear of an engine's crankshaft. Its purpose is to smooth out the shock caused by firing cylinders. The flywheel also provides a surface on which the clutch disc can engage and has a ring gear around the circumference to mate with the starter motor.
Symptoms of Wear or Failure
- Abnormal noise when starter motor is engaged
- The clutch may "grab" when engaging
Related Repair Advice
- The flywheel surface should be inspected and refinished as necessary whenever the clutch is replaced
