3.6.31. Checking torsion vibration
damper of 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, exchan-
ge 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.
