Engine Flywheel Cleaning and Inspection
WARNING: This page is about a different variant/trim than selected.
- NOTE:
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 (1) in solvent.
- 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
- Rotate the clutch side half of the flywheel.
- There should be play of up to +/- 4 degrees of rotation before it engages the inner springs of the dual mass flywheel.
- A torque of 140 - 230 N.m (103 - 170 lb ft) should be obtained at 42 degrees of rotation.
- No scraping or grinding noises should be heard during rotation. Replace the flywheel if any conditions are found.
Inspect the automatic transmission flywheel for the following:
- Damaged ring gear teeth
- Stress cracks around the flywheel-to-crankshaft bolt hole locations
- Weight saving holes
