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.
 
Caution: Wear safety glasses in order to avoid eye damage.
- Dry the flywheel with compressed air.
 
- Inspect the manual transmission flywheel for the following:
 
| •  | Damaged ring gear teeth | 
 
| •  | 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. | 
 
| •  | A scored, grooved or damaged friction surface |
