4. Remove front wheel from the machine (see Wheel
Removal in the Service and Repairs section of Chapter
6 -- Chassis). Remove wheel spacer (item 4).
IMPORTANT: DO NOT hit wheel hub, puller or wheel
motor with a hammer during wheel hub removal or
installation. Hammering may cause damage to the
wheel motor.
5. Make sure that lock nut on wheel motor shaft is loos-
ened at least two (2) turns. Use hub puller (see Special
Tools in this chapter) to loosen wheel hub from wheel
motor.
6. Remove lock nut (item 15) and wheel hub from motor
shaft. Discard lock nut. Locate and retrieve square key
(item 7).
7. Thoroughly clean hydraulic tube ends and fittings on
wheel motor to prevent hydraulic system contamination.
8. Loosen and remove hydraulic tubes from fittings on
wheel motor. Allow tubes to drain into a suitable contain-
er.
9. Put clean plugs in disconnected hydraulic tubes and
fittings to prevent system contamination.
10.Support the wheel motor to prevent it from falling dur-
ing removal.
11. Remove four (4) cap screws that secure wheel motor
to the steering fork.
12.Remove wheel motor from steering fork.
13.If removal of wheel motor hydraulic fittings is neces-
sary, mark fitting orientation to allow correct assembly.
Remove hydraulic fittings from wheel motor. Remove
and discard O--rings from fittings.
Installation (Fig. 49)
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 front wheel motor to steering fork. Make
sure that ports in wheel motor are facing toward rear of
machine.
4. Apply Loctite #271 (or equivalent) to threads of cap
screws. Secure front wheel motor to steering fork with
four (4) cap screws. Torque cap screws from 94 to 116
ft- -lb (128 to 157 N- -m).
IMPORTANT: Before wheel hub is installed, thor-
oughly clean tapers of wheel hub and wheel motor
shaft. Make sure that tapers are free of grease, oil,
rust and dirt. Do not use antiseize lubricant when
installing wheel hub.
5. Mount square key (item 7) in the wheel motor shaft,
then install the wheel hub onto the wheel motor shaft.
IMPORTANT: Do not reuse lock nut that secures
wheel hub to wheel motor after it has been removed.
6. Install new lock nut (item 15) onto the wheel motor
shaft to secure wheel hub to motor shaft.
7. Remove plugs from disconnected hydraulic tubes
and wheel fittings.
8. Connect hydraulic tubes to wheel motor fittings (see
Hydraulic Hose and Tube Installation in the General In-
formation section of this chapter).
9. Install wheel spacer (item 4) and wheel assembly to
the machine (see Wheel Installation in the Service and
Repairs section of Chapter 6 -- Chassis).
10.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.
11. Torque lock nut (item 15) 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).
12.Make sure hydraulic tank is full. Add correct oil if nec-
essary.
