Removal (Fig. 53)
1. Park machine on a level surface, stop engine, en-
gage parking brake and remove key from the ignition
switch.
CAUTION
Rotate steering wheel and depress traction ped-
al in both forward and reverse to relieve hydrau-
lic system pressure and to avoid injury from
pressurized hydraulic oil.
2. Operate all hydraulic controls to relieve hydraulic
system pressure.
3. Read the General Precautions for Removing and
Installing Hydraulic System Components at the begin-
ning of the Service and Repairs section of this chapter.
4. To prevent contamination of hydraulic system during
motor removal, thoroughly clean exterior of motor and
fittings.
5. For assembly purposes, label the hydraulic lines to
show their correct position on the wheel motor.
6. Disconnect hydraulic lines from fittings on wheel mo-
tor. Put caps or plugs on hydraulic lines and fittings to
prevent contamination.
7. If right side wheel motor is being removed, unplug
speed sensor connector from machine wire harness.
IMPORTANT: Before loosening wheel motor fasten-
ers, support motor to prevent it from falling.
8. Support the motor assembly to prevent it from falling.
Remove two (2) cap screws and flat washers that secure
wheel motor to brake and planetary assemblies. Re-
move wheel motor from machine.
9. If hydraulic fittings are to be removed from wheel mo-
tor, mark fitting orientation to allow correct assembly.
Remove fittings from motor and discard O--rings.
Installation (Fig. 53)
1. If fittings were removed from wheel motor, lubricate
and place new O--rings onto fittings. Install fittings into
motor port openings using marks made during the re-
moval process to properly orientate fittings. Tighten fit-
tings (see Hydraulic Fitting Installation in the General
Information section of this chapter).

2. If splined brake shaft was removed from brake as-
sembly, make sure that the stepped end of the shaft is
aligned toward the hydraulic wheel motor (Fig. 54). Also,
make sure that splines engage rotating discs in brake
assembly.
3. Install O--ring (item 9) onto motor. Position wheel
motor to brake assembly.
4. Align splines on motor shaft and splined brake shaft.
Slide motor into brake assembly.
5. Secure motor to brake and planetary assemblies
with cap screws and flat washers. Torque cap screws 60
ft- -lb (81 N- -m).
6. Remove plugs from hydraulic lines, fittings and
ports. Lubricate new O--rings and attach hydraulic lines
to wheel motor (see Hydraulic Hose and Tube Installa-
tion in the General Information section of this chapter).
7. If right side wheel motor was removed, plug speed
sensor connector into machine wire harness.
8. Check fluid level in hydraulic oil reservoir and adjust
as required.
9. Operate machine and inspect for leaks.
