Caution

• Do not rework the dual-mass flywheel if it is distorted.

• Do not clean the dual-mass flywheel with any kind of fluid. Clean the dual-mass 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.

Inspection Before Removal

1.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.

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.

2.Measure the amount of guide pin projection of the dual-mass flywheel.

• If it exceeds the maximum amount, replace the dual-mass flywheel.

Inspection After Removal

1.Visually inspect the dual-mass flywheel for crack.

• If there is any crack, replace the dual-mass flywheel.

2.Visually inspect the ring gear on the dual-mass flywheel for damage.

• If there is any damage, replace the dual-mass flywheel.

3.Visually inspect the surface that contacts the clutch disc for scratches, nicks, and discoloration.

• If there is any malfunction, replace the dual-mass flywheel.

Note

• Correct slight scratches and discoloration using sandpaper.

4.Visually inspect for grease leakage between the primary mass and secondary mass.

• If there is grease leakage, replace the dual-mass flywheel.
