Engine Flywheel Clean and Inspect





1. Clean the flywheel in solvent.

Caution: Wear safety glasses in order to avoid eye damage.

2. Dry the flywheel with compressed air.





3. Inspect the manual transmission flywheel for the following:
^ Damaged ring gear teeth.
^ Loose or improperly positioned ring gear.

The ring gear has an interference fit onto the flywheel and should be positioned completely against the flange of the flywheel.
4. A scored, grooved or damaged friction surface





5. Inspect the automatic transmission flywheel for the following:
^ Damaged ring gear teeth
^ Stress cracks around the flywheel-to-crankshaft bolt hole locations.

Important: Do not attempt to repair the welded areas that retain the ring gear to the flywheel plate. Install a new flywheel.

^ Welded areas that retain the ring gear onto the flywheel for cracking.
