1. Install a dial gauge on the cylinder block.
2. Measure the flywheel runout using a dial gauge.
-
Flywheel maximum runout
-
L8, LF, L3: 0.1 mm {0.004 in}
-
• If it exceeds the maximum specification, replace the flywheel.
Dual-mass Flywheel Inspection [L3 Turbo, MZR-CD (RF Turbo)]
-
Caution
-
• Do not rework the flywheel if it is distorted.
• Do not clean the dual mass flywheel with any kind of fluid. Clean the flywheel with a dry cloth only.
• Do not clean the gap between the primary and secondary mass. Only clean the bolt connection surface and the clutch surface.
1. Remove the manual transaxle. (See MANUAL TRANSAXLE REMOVAL/INSTALLATION [A26M-R].) (See MANUAL TRANSAXLE REMOVAL/INSTALLATION [A26MX-R].)
2. Remove the clutch cover and clutch disc. (See CLUTCH UNIT REMOVAL/INSTALLATION [L3 Turbo].) (See CLUTCH UNIT REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
3. Inspect the rotation of the dual-mass flywheel for play.
- (1) Lock the dual-mass flywheel using the SST (49 E011 1A0).
- (2) Rotate the secondary flywheel clockwise by hand until resistance can be felt.
- (3) Mark the guide pin position on the ring gear of the flywheel.
- (4) Rotate the secondary flywheel counterclockwise by hand until resistance can be felt.
- (5) Mark the guide pin position on the ring gear of the primary flywheel again.
- (6) Verify that the play is within the range of 4 teeth.
-
-
-
Caution
-
• It may not be possible to rotate the secondary flywheel due to the functionality of the dual-mass flywheel.
In this case, the dual-mass flywheel can be considered normal by reason of the play being within the range of 4 teeth.
4. Remove the flywheel.
-
Note
-
• Correct slight scratches and discoloration using sandpaper.
• Inspect the runout of the surface that contacts the clutch disc with the flywheel installed to the crankshaft.
5. Inspect the 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 flywheel.
6. Visually inspect the secondary mass.
-
• If there is any damage, replace the dual-mass flywheel.
7. Visually inspect the ring gear on the dual-mass flywheel.
-
• If there is any damage, replace the dual-mass flywheel.
8. Inspect the welded area of the dual-mass flywheel for grease leakage.
-
• If there is grease leakage, replace the dual-mass flywheel.
9. Inspect the dual-mass flywheel for the amount of guide pin projection.
-
• If not within the specification, replace the dual-mass flywheel.
10. Inspect the dual-mass flywheel for cracks.
-
• If there are cracks, replace the dual-mass flywheel.
