Examine the vibration damper, rubber
1 Examine the index lines (A) in the vibration damper hub (B)
and the inertia member (C). If the lines are more than 1,59
mm (1/16 in) out of alignment, replace the vibration damper.
2 Examine the rubber member for deterioration. If pieces of rub‐
ber are missing or if the elastic member is more than 3,18 mm
(1/8 in) below the metal surface, replace the damper.
3 Look for forward movement of the damper ring on the hub.
Replace the vibration damper if any movement is detected.
4 For vibration damper location, refer to engine drawings.
Examine the vibration damper, viscous
1 Examine the vibration damper for evidence of fluid loss,
dents, and wobble. Examine the vibration damper thickness
for any deformation or raising of the damper cover plate.
CAUTION
The silicone fluid in the vibration damper will become solid after
extended service and will make the damper inoperative. An inoper‐
ative vibration damper may cause major engine or drivetrain fail‐
ures.
2 If any of these conditions are identified, contact an authorized
repair location to replace the vibration damper.
3 For vibration damper location, refer to engine drawings.
