Flywheel: Testing and Inspection

1. Inspect the contact surface for scoring, cracks, and burning.





2. Remove minor scoring or burning by using emery paper. Repair if scoring or burning is major. Replace if cracked.
3. Inspect the ring gear teeth for wear and damage. If necessary, replace the ring gear.





4. Measure the flywheel runout by using a dial indicator. Replace the flywheel if runout is excessive. Runout should be 0.200 mm (0.0079 inch) maximum.
