NOTE: Early models have two bolts (A) attaching

differential to frame support bracket (C). Later
models have one shoulder bolt (A) or one bolt
with a washer and spacer.

IMPORTANT: It is recommended to replace the early

model differential frame support
bracket (C) with the later configuration
(D). The early models attached the
differential to the frame support bracket
with two bolts (A). One in the
differential case and the other in the
differential cover. When the machine

Early Models

went over rough terrain, the flexing of
the cover and case caused the
differential gasket to leak. With the later
model frame support bracket installed,
the slotted hole and single shoulder
bolt (A) (attached to the case only) will
allow for flexing, eliminating any
possible leaks.

bracket (D).
