Check Runout
1. Remove belts (shown removed).
2. Grasp vibration damper with both hands and attempt to
turn it in both directions. If rotation is felt, damper is
defective and should be replaced.
IMPORTANT: The vibration damper assembly is not
repairable and should be replaced every
4500 hours or 60 months, whichever
occurs first.
3. Check vibration damper radial runout by positioning a
dial indicator (A) so probe contacts damper outer
diameter.
4. With engine at operating temperature, rotate crankshaft
using either JDE83 or JD81-1 Flywheel Turning Tool.
5. Note dial indicator reading. If runout exceeds
specifications given below, replace vibration damper.
