Axle Disassembly Procedure
The trunnion option axle is serviced identically
internally to the “less trunnion” axle assembly unless
where noted in this manual. The same is true for the
axle with wet brakes and “less wet brakes”
feature.
The manual is written to service the standard axle
and each optional feature has been reviewed in
separate sections as the trunnion and wet brake
are available in both the rigid mount and trunnion
mount axle designs. The following procedure is
recommended to disassemble the axle assembly
.
Wheel End Disassembly Procedure
If the axle being serviced has the trunnion optional
feature, the trunnion components should be removed
first. Once the trunnion components are removed or
the axle is “less trunnion” feature, continue with the
following disassembly procedure.
NOTE: There may be some small quantity of oil
remaining within the planetary wheel end reduction
when the planetary assembly is opened. Care should
be taken to capture this small amount of oil for safe
and recommended disposal practices.
1. Remove the M18 capscrews and washers from the
spindle to axle housing joint. Figure 2.7.
