Important: In order to maintain the proper component balance, contact surface taper and heat transfer, manual transmission flywheels are NOT to be machined.
Caution: Wear safety glasses in order to avoid eye damage.
- Clean the engine flywheel (1 or 2) in cleaning solvent.
- Dry the engine flywheel with compressed air.
Important: Do not attempt to repair the welded areas, if present, that retain the ring gear to the engine flywheel plate. Always install a NEW engine flywheel.
- Inspect the engine flywheel, automatic transmission, if equipped, for the following:
• | Stress cracks around the engine flywheel-to-torque converter bolt hole locations (1) |
• | Missing balance weights |
• | Stress cracks around the engine flywheel-to-crankshaft bolt hole locations (2 or 3) |
• | Welded areas that retain the ring gear onto the engine flywheel for cracking (4), if present |
• | Damaged ring gear teeth (5) |
- Inspect the engine flywheel, manual transmission, if equipped, for loose or improperly installed flywheel weights, if applicable.
A properly installed flywheel weight should be installed until flush or below flush
with the face of the engine flywheel.
- Inspect the engine flywheel, manual transmission, if equipped, for the following:
• | Pitted friction surface (1) |
• | Rust or other surface damage (3) |
• | Damaged ring gear teeth (4) |
• | Loose or improperly positioned ring gear |
• | The ring gear has an interference fit onto the engine flywheel and the ring gear should be positioned completely flat against the flange of the engine flywheel. |
