WARNING
Before jacking up the machine, review and follow
Jacking Instructions in Chapter 1 - - Safety.
3. Jack up machine enough to allow the removal of the
rear wheel. Support machine with jack stands.
4. Remove wheel assembly (item 1), brake drum (item
23), wheel hub (item 22) and brake assembly (item 3)
from the machine (see Brake Service in the Service and
Repairs section of Chapter 6 -- Chassis).
5. Thoroughly clean hydraulic hose ends and fittings on
wheel motor to prevent hydraulic system contamination.
6. Loosen and remove hydraulic tubes from fittings on
wheel motor. Allow tubes to drain into a suitable contain-
er.
7. Put clean plugs in disconnected hydraulic tubes and
fittings to prevent system contamination.
8. Support the wheel motor to prevent it from falling dur-
ing removal.
9. Remove four (4) cap screws that secure wheel motor
and brake support to the machine.
10.Remove wheel motor and brake support from steer-
ing fork.
11. If removal of wheel motor hydraulic fittings is neces-
sary, mark fitting orientation to allow correct assembly.
Remove hydraulic fittings from wheel motor (Fig. 48).
Remove and discard O--rings from fittings.
Installation (Fig. 47)
IMPORTANT: Because of internal differences in
wheel motors, DO NOT interchange wheel motors
on machine (i.e. do not put RH motor on left side of
machine). If necessary, use parts catalog and part
number on wheel motor to identify RH and LH mo-
tors.
1. If fittings were removed from wheel motor, lubricate
and install new O--rings to hydraulic fittings. Install fit-
tings into wheel motor ports (see Hydraulic Fitting Instal-
lation in the General Information section of this chapter).
Make sure that fittings are orientated correctly.
2. Clean threads in steering fork and on cap screws
used to secure wheel motor to machine.

3. Position rear wheel motor to steering fork. Make sure
that ports in wheel motor are facing forward.
4. Apply Loctite #271 (or equivalent) to threads of cap
screws. Secure rear wheel motor and brake support to
steering fork with four (4) cap screws. Torque cap
screws from 94 to 116 ft- -lb (128 to 157 N- -m).
5. Remove plugs from disconnected hydraulic tubes
and wheel fittings.
6. Connect hydraulic tubes to wheel motor fittings (see
Hydraulic Hose and Tube Installation in the General In-
formation section of this chapter).
7. Install brake assembly (item 3), wheel hub (item 22),
brake drum (item 23) and wheel assembly (item 1) to the
machine (see Brake Service in the Service and Repairs
section of Chapter 6 -- Chassis).
8. Lower the machine to the ground.
Failure to properly torque wheel lug nuts and
wheel hub lock nut could result in failure or loss
of wheel and may result in personal injury.
9. Torque lock nut (item 20) from 300 to 400 ft- -lb (407
to 542 N- -m). Also, make sure that wheel lug nuts are
torqued evenly in a crossing pattern from 75 to 85 ft- -lb
(102 to 115 N- -m).
10.Make sure hydraulic tank is full. Add correct oil if nec-
essary.
