For 1990-2009 cars

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.
2. Dry the flywheel with compressed air.
3. Inspect the manual transmission flywheel for loose or improperly installed balance weights (if applicable).

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 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 two locating pins are installed into the flywheel and spaced 170 degrees apart.

5. Inspect the automatic transmission flywheel for the following:

• | Damaged ring gear teeth

• | Stress cracks around the flywheel-to-crankshaft bolt hole locations

| 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
