Tools Required

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. Replace the flywheel if the ring gear is damaged, cracked or worn.

•	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.

•	A scored, grooved or damaged friction surface. Replace the flywheel if the surface is damaged or excessively worn.




4. Inspect the automatic transmission flywheel for the following:

•	Damaged ring gear teeth. Replace the flywheel if the ring gear is damaged, cracked or worn.

•	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.




5. Measure the flywheel face runout using a J 8001 with a J 26900-13 . Replace the flywheel if the runout exceeds 0.2 mm (0.0078 in).
