Engine Flywheel Cleaning and Inspection





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.

Caution: Refer to Safety Glasses Caution.

2. Dry the flywheel with compressed air.
3. Inspect the flywheel for the following conditions:

* 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 (5)
The 3 locating pins are installed into the flywheel and spaced 120 degrees apart in order to ensure proper orientation of the clutch pressure plate to the flywheel during assembly.
