Engine Flywheel Cleaning and Inspection
- Clean the flywheel in solvent.
- Dry the flywheel with compressed air.
- Inspect the manual transmission flywheel for the following conditions:
- Pitted surfaces (1)
- Grooves or scoring (2)
- Rusted surface (3)
- Damaged ring gear teeth (4)
- 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 2 locating pins are installed into the flywheel and spaced 170 degrees apart.
- Inspect the automatic transmission flex plate for the following conditions:
- Damaged ring gear teeth
- Stress cracks around the flex plate-to-crankshaft bolt hole locations
- Welded areas that retain the ring gear onto the flex plate for cracking
IMPORTANT: Do not attempt to repair the welded areas that retain the ring gear to the flex plate. Install a new flex plate.
IMPORTANT:
In order to maintain the proper component balance, contact surface taper, and heat transfer, manual transmission flywheels are NOT to be machined.
