2. Dry the flywheel with compressed air.





3. 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.
