the engine
• Check the position of pressed marks on the face of both
parts of torsion vibration damper. If the marks are
shifted from each other by more than 1.59 mm (1/16 in),
it is necessary to exchange the damper.
• Check whether the rubber component (3) is not higher
or lower above the level of metal parts (1) and (2) by
more than 3.18 mm (1/8 in). If the limit is exceeded,
exchange torsion vibration damper.
• Check visually whether the torsion vibration damper is
not moving forward. Check th vibration damper for
evidence of fluids loss, dents and wobble.
! NOTE !
With time, the flexible silicone filling of the damper
gets rigid and no longer works properly. Non-
working damper may cause considerable damage to
the engine.
