Flywheel: Testing and Inspection
FLYWHEEL INSPECTION [A26M-R]
CAUTION:
1 Secure the steering wheel using tape or a cable to prevent the steering shaft from rotating after disconnecting the steering shaft. If the steering wheel rotates after the steering shaft and the steering gear and linkage are disconnected, the internal parts of the clock spring could be damaged.
2 Do not rework the dual-mass flywheel if it is distorted.
3 Do not clean the dual-mass flywheel with any kind of fluid. Clean the dual-mass flywheel with a dry cloth only.
4 Do not clean the gap between the primary and secondary mass. Only clean the bolt connection surface and the clutch surface.

NOTE:
1 Correct slight scratches and discoloration using sandpaper.
2 Inspect the runout of the surface that contacts the clutch disc with the dual-mass flywheel installed to the crankshaft.
11. Inspect the dual-mass flywheel.
- Cracks
- Worn ring gear teeth
- Chipped or cracked ring gear teeth
- Surface that contacts the clutch disc for scratches, nicks, and discoloration.
- If there is any malfunction, replace the dual-mass flywheel. Service and Repair
12. Verify that the center of the dual-mass flywheel does not move.
a. Rotate the dual-mass flywheel or attempt to move it up and down, and left and right to verify that the center of the dual-mass flywheel does not move.
- If there is any movement as indicated by the arrows in the figure, replace the dual-mass flywheel with a new one. Service and Repair
13. Verify that the secondary mass rotates by 15 teeth or more.
- If it rotates by 15 teeth or more, replace the dual-mass flywheel. Service and Repair
14. Inspect for locating dowels touching the primary mass of the dual-mass flywheel.
CAUTION:
- Make sure that the three locating dowels are installed.
- If the locating dowels are touching the primary mass of the dual-mass flywheel, replace the dual-mass flywheel with a new one.
15. Visually inspect the secondary mass.
- If there is any damage, replace the dual-mass flywheel. Service and Repair
16. Visually inspect the ring gear on the dual-mass flywheel.
- If there is any damage, replace the dual-mass flywheel. Service and Repair
17. Inspect the welded area of the dual-mass flywheel for grease leakage.
- If there is grease leakage, replace the dual-mass flywheel. Service and Repair
18. Inspect the dual-mass flywheel runout.
- If it is more than the maximum specification, replace the dual-mass flywheel. Service and Repair
Flywheel maximum runout [A26M-R]
- 1.5 mm {0.059 in}
19. Inspect the dual-mass flywheel for the amount of guide pin projection.
- If not within the specification, replace the dual-mass flywheel. Service and Repair
20. Rotate the secondary mass left and right and verify that it rotates within a range of three teeth without resistance.
- If there is any malfunction, replace the dual-mass flywheel. Service and Repair
21. Inspect the dual-mass flywheel for cracks.
- If there are cracks, replace the dual-mass flywheel. Service and Repair
22. Install in the reverse order of removal.
23. Perform the auto leveling system initialization. Programming and Relearning
24. Add the specified amount of specified transaxle oil. Transaxle Oil Replacement
25. Warm up the engine and transaxle, inspect for oil leakage, and inspect the transaxle operation.
WARNING:
- Improperly jacking a transaxle is dangerous. It can slip off the jack and may cause serious injury.
NOTE:
- If the transaxle is overhauled and installed to the vehicle, perform the 'INSPECTION AFTER TRANSAXLE OVERHAUL' and verify that there is no abnormality. Inspection After Transaxle Installation
