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.

2. Dry the flywheel with compressed air.




3. Inspect the manual transmission flywheel for the following conditions:
^ 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.
^ A scored, grooved or damaged friction surface




4. Inspect the automatic transmission flywheel for the following conditions:
^ Damaged ring gear teeth
^ Stress cracks around the flywheel-to-crankshaft bolt hole locations
^ Weight saving holes
