Installation (Fig. 45)
1. Carefully raise rear differential into machine from the
rear of the machine. Support differential in position to
prevent it from shifting or falling.
NOTE: When securing the rear differential to the ma-
chine, loosely install all fasteners before fully tightening
any of the fasteners.
2. On the sides of the rear differential, install flange
head screws that secure the differential to the engine/
transmission mount.
3. On the front of the rear differential, install two (2)
flange head screws that secure the differential to the en-
gine/transmission mount.
4. Position LH and RH rear mounts to machine frame
and rear differential and install removed fasteners to se-
cure the mounts. Make sure that solenoid controller as-
sembly (item 22) is secured to the machine frame with
fasteners for the RH rear mount.
5. Tighten all fasteners to secure rear differential to ma-
chine.
6. Install both CV axle assemblies with attached wheel
hubs to machine (see Rear CV (Constant Velocity) Axles
in this section). Make sure that flange head screws that
secure wheel hub to rear axle are torqued from 35 to 40
ft−lb (48 to 55 N−m).
7. Install rear brake rotor, brake caliper and wheel as-
sembly to both sides of machine (see Brake System in
the Service and Repairs section of Chapter 5 − Chassis).
