How to check the condition of the
vibration damper
Caution: A vibration damper (figure 27 items 1)
should be renewed if there is impact damage to the
outer casing or if there is leakage of the viscous fluid
from the cover plate.
Check the area around the holes for the damper
bolts for cracks and general wear if the damper has
become loose in service.
Check that the six bolts (figure 27 item 2) for the
viscous damper are tightened correctly:
Tighten the six M12 bolts to 115 Nm (85 lb ft).
If it is necessary to renew the vibration damper refer
to the workshop manual.
