Crankshaft Vibration Damper
- Inspect
Damage to the crankshaft vibration damper or failure
of the crankshaft vibration damper can increase
torsional vibrations. This can result in damage to
the crankshaft and to other engine components. A
deteriorating damper can cause excessive gear train
noise at variable points in the speed range.
The damper is mounted to the crankshaft which is
g00285520
located behind the belt guard on the front of the
engine.
Removal and Installation
Refer to the Service Manual for the damper removal
procedure and for the damper installation procedure.

Inspect the wiring harness for good connections.
If the cylinder head grounding stud is installed, the
cylinder head grounding stud must have a wire
ground to the battery. Tighten the cylinder head
grounding stud at every oil change. Ground wires
and straps should be combined at engine grounds.
All grounds should be tight and free of corrosion.
