34. Engine Flywheel Clean and Inspect
Engine Flywheel Cleaning and InspectionImportant: 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 loose or improperly installed balance weights.
A properly installed balance weight should be installed until flush or below flush with the face of the flywheel.
4. Inspect the manual transmission flywheel for the following:
- Pitted surface (1)
- Grooved or scored surface (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 to ensure proper orientation of the clutch pressure plate to the engine flywheel during assembly.
5. Inspect the automatic transmission flywheel for the following:
- Damaged ring gear teeth
- Stress cracks around the flywheel-to-crankshaft bolt hole locations
- Worn prop shaft drive hub splines
- Loose prop shaft drive hub
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
