3. Inspect the flex plate for the following conditions:

•	Damaged ring gear teeth (1).

•	Elongations of the crankshaft or torque converter bolt holes (2).

•	Stress cracks around the flex plate-to-crankshaft retaining bolt hole locations (3).

•	Cracks between the pressing holes (4).

•	Welded areas that retain the ring gear onto the flex plate for cracking.

1. Clean the manual transmission flywheel in solvent.
2. Dry the flywheel with compressed air.

Important: Do not attempt to repair the welded areas that retain the ring gear to the flywheel. If any of the following conditions are found, install a new flywheel.

3. Inspect the flywheel for the following conditions:

•	Pitted surfaces (4)

•	Grooved or scored surface (2)

•	Rusted surface (3)

•	Damaged ring gear teeth (1)

•	Loose or incorrectly 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 correct orientation of the clutch pressure plate to the engine flywheel during assembly.
