E5: CHECK THE ROTATION OF THE SECONDARY MASS OF THE DUAL MASS FLYWHEEL

CAUTIONS:

Do not rework or machine the dual mass

flywheel if it is distorted.

Do not clean the dual mass flywheel with any

kind of liquid. Use only a dry cloth to clean the
flywheel.

Do not clean the gap between the primary and

secondary mass. Only clean the bolt connection
surface and the clutch surface.
NOTE: Discoloration is not a reason in itself to
replace the dual mass flywheel.
