Check Vibration Damper
--- Every 2000 hours
1. Park the machine following the same procedure as
described on page 7-8 for preparation of inspection/
maintenance work.
d
CAUTION: The silicone fluid in the vibration
damper will become solid after extended service
and will make the damper inoperative. An
inoperative vibration damper can cause major
engine or drivetrain failures.
2. Check vibration damper (1) on the fan end of the
engine crankshaft for evidence of fluid loss, dents,
and wobble.
Inspect the vibration damper thickness for any
deformation or raising of the damper cover plate.
3. If any of these conditions are identified, consult your
authorized dealer for check and repair.
4. Check the index lines (A) on the 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 damper.
5. Inspect the vibration damper hub (B) for cracks.
Replace the damper if the hub is cracked.
6. Inspect the rubber member for deterioration.
If pieces of rubber are missing or if the elastic
member is more than 3.18 mm (1/8 in) below the
metal surface, replace the damper.
f
NOTE: Also look for forward movement of the damper
ring on the hub. Replace the damper if any movement is
detected.
