Disassemble Carrier Assembly

Note: For models having the wheel differential lock option or a

carrier thrust bolt follow the steps below. These parts
must be removed first before further removal of the
wheel differential can take place.

Disassemble Wheel Differential – Models with Wheel
Differential Lock

1. For ease of servicing, mount differential carrier in

stand with differential lock facing up.

Note: To overhaul and reassemble the wheel differential, the

shift fork and clutch assembly must be removed from
carrier. See instructions below.

2. Remove shift cylinder mounting screws, then lift

shift cylinder, piston and o-ring assembly off carrier
and end of push rod.

3. To disassemble shift cylinder for inspection, first

remove or back off actuator switch. The piston and
o-ring assembly can be removed by inserting a pen-
cil-size tool through the cylinder air port.

4. Grasp push rod end and pull it out of the shift fork,

spring and carrier.

Note: When the push rod is disengaged from the shift fork,

the fork and sliding curvic clutch assembly can be
removed from carrier.

Note: Do not disassemble shift fork from the sliding curvic

clutch unless parts replacement is necessary. To disas-
semble, use pin punch to remove spring pin from long
leg of fork. The fork can now be disengaged from the
clutch.

5. Remove the snap ring, then lift fixed curvic clutch off

differential case hub spline. Further disassembly of
carrier is the same for axles without differential lock.

Models with Ring Gear Thrust Bolt

Note: If the carrier model has a ring gear thrust bolt installed,

it must be backed away from the ring gear before you
can remove the wheel differential.

1. Back off thrust bolt jam nut.

2. Back out thrust bolt from the carrier until the end of

the bolt is flush with the inside of the carrier casting.
This will allow enough clearance between the ring
gear and the carrier pilot web.
