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 [A26MX-R (MZR-CD 2.2)].)

2.Remove the clutch cover and clutch disc. (See CLUTCH UNIT REMOVAL/INSTALLATION [MZR-CD 2.2].)

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.

• If the play is 5 teeth or more, replace the dual-mass flywheel. (See CLUTCH UNIT REMOVAL/INSTALLATION [MZR-CD 2.2].)

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. (See MANUAL TRANSAXLE REMOVAL/INSTALLATION [A26MX-R (MZR-CD 2.2)].)

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. (See MANUAL TRANSAXLE REMOVAL/INSTALLATION [A26MX-R (MZR-CD 2.2)].)

6.Visually inspect the secondary mass.

• If there is any damage, replace the dual-mass flywheel. (See MANUAL TRANSAXLE REMOVAL/INSTALLATION [A26MX-R (MZR-CD 2.2)].)

7.Visually inspect the ring gear on the dual-mass flywheel.

• If there is any damage, replace the dual-mass flywheel. (See MANUAL TRANSAXLE REMOVAL/INSTALLATION [A26MX-R (MZR-CD 2.2)].)

8.Inspect the welded area of the dual-mass flywheel for grease leakage.

• If there is grease leakage, replace the dual-mass flywheel. (See MANUAL TRANSAXLE REMOVAL/INSTALLATION [A26MX-R (MZR-CD 2.2)].)

9.Inspect the dual-mass flywheel for the amount of guide pin projection.

acxwzw00000478

• If not within the specification, replace the dual-mass flywheel. (See MANUAL TRANSAXLE REMOVAL/INSTALLATION [A26MX-R (MZR-CD 2.2)].)

10.Inspect the dual-mass flywheel for cracks.

• If there are cracks, replace the dual-mass flywheel. (See MANUAL TRANSAXLE REMOVAL/INSTALLATION [A26MX-R (MZR-CD 2.2)].)

11.Install in the reverse order of removal.

12.Start the engine. And inspect and adjust the following:

• Front wheel alignment (See FRONT WHEEL ALIGNMENT.)

• Power steering fluid air bleeding (See CLUTCH FLUID AIR BLEEDING/REPLACEMENT.)

• Leakage of engine oil, engine coolant, transaxle oil.

• Runout and contact of pulley and belt.

• Verify the idle speed. (See ENGINE TUNE-UP [MZR-CD 2.2].)

• Engine-driven accessories operation.
