Important: In order to maintain the proper component balance, contact surface taper, and heat transfer, manual transmission flywheels are NOT to be machined.
- Clean the flywheel in solvent.
- Dry the flywheel with compressed air.
- Inspect the manual transmission flywheel for the following conditions:
| • | 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 |
| | Important: Do not attempt to repair the welded areas that retain the ring gear to the flex plate. Install a new flex plate.
|
| • | Welded areas that retain the ring gear onto the flex plate for cracking |
