Engine Flywheel Cleaning and Inspection





Important: In order to maintain the proper component balance, contact surface taper, and heat transfer, manual transmission flywheels are NOT to be machined.

1. Clean the flywheel in solvent.

Caution: Refer to Safety Glasses Caution in Service Precautions.

2. Dry the flywheel with compressed air.
3. Inspect the manual transmission flywheel for the following:
^ Pitted surfaces
^ Grooves or scoring
^ Rusted surface
^ 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.
^ Missing, bent, or damaged pressure plate locating pins
The two locating pins are installed into the flywheel and spaced 170 degrees apart.





4. 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
