Flywheel: Testing and Inspection
Flywheel Inspection
NOTICE: Do not clean the dual mass flywheel with any kind of fluid, use a dry cloth only or damage to the dual mass flywheel may occur.
NOTICE: Do not clean the gap between the primary and secondary mass. Only clean the bolt connection surface and the clutch surface or
damage to the flywheel may occur.
1. Check the transaxle fluid level and fill to the correct level as necessary.
2. With the engine operating at idle and the transaxle in NEUTRAL, listen and check for unacceptable noise. Determine if any unacceptable noise is
reduced when the clutch pedal is depressed.
3. If unacceptable noise is identified, remove the transaxle. For additional information, refer to Manual Transmission/Transaxle.
4. Inspect the clutch slave cylinder for leaks. If a leak is identified, install a new clutch slave cylinder. For additional information, refer to Manual
Transmission/Transaxle.
5. Inspect the sliding surfaces of the clutch release hub and bearing. Any scoring or burr should be removed with a fine grade of emery paper.
6. Inspect the transaxle input shaft for spline wear, scoring or burrs. Any scoring or burr should be removed with a fine grade of emery paper. If
spline wear is identified, install a new transaxle. For additional information, refer to Manual Transmission/Transaxle.
7. NOTE: The clutch disc should be discarded due to possible hub spline wear or friction material wear.
Remove the clutch disc and pressure plate.
-
Discard the clutch disc.
8. Inspect the clutch pressure plate and diaphragm spring segments and discard as necessary.
-
Inspect the clutch pressure plate for scoring, cracks or discoloration. Any minor scoring or discoloration should be removed with a fine grade
of emery cloth.
-
Inspect the clutch diaphragm spring segments for damage, uneven height, scoring, cracks or discoloration. Any minor scoring or discoloration
should be removed with a fine grade of emery cloth.
9. NOTE: The flywheel cannot be machined.
With the dual mass flywheel installed on the engine, inspect the dual mass flywheel surface for scoring, cracks, discoloration or damage. If any of
these conditions exist, install a new flywheel.
10. Using a suitable long screwdriver or bar, firmly rotate the secondary mass clockwise and counterclockwise until the dual mass flywheel friction
control plate is centered between the secondary mass notches.
