TIMING, GEAR TRAIN & FRONT COVER
Prior to removing the crankcase front cover it will be
necessary to remove "other equipment" (i.e. alternator,
air and freon compressor, steering and vacuum pump
etc.), depending upon the application. Refer to the
Operators Manual and Service Manual to determine
When the Front Cover is free of applicable
accessories remove it as follows:
NOTE: Observe the variations which exist between
the Agricultural Equipment, Payline and Truck
Engines with "RUBBER"* vibration dampers
should be checked for wobble before removing.
Attach a dial indicator to the vibration
damper flange as shown in Fig. 7.
Check at least four points 90 apart.
If wobble exceeds 1.5 mm (0.06 in.) total
indicator reading, replace the damper.
* Damper is not made of rubber, rather it has a rubber
Figure 7. - Checking "Rubber" Damper for Wobble
Remove "RUBBER" vibration damper as follows:
Remove the cap screws, damper plate (if
equipped) and retainer plate securing the
vibration damper to the crankshaft.
Engines equipped with the Three-Hole
Damper (1, Fig. 8) must use the puller 89-
10-17 (2) for early Agricultural and Payline
Equipment as shown in Fig. 8.
NOTE: It Is necessary to modify the puller bolt holes
with a file to match the bolt pattern of the damper

Late model Agricultural equipment requires
the puller 04-33-3 (2, Fig. 9) to remove the
vibration damper (1) as shown.
