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. Install a dial indicator on the cylinder block.





5. Measure the flywheel runout by using a dial indicator. Replace the flywheel if runout is excessive. Runout should be 0.2 mm (0.0079 inch) maximum.
