Removal (Fig. 6)
1. Park machine on a level surface, lower cutting deck,
stop engine, engage parking brake and remove key
from the ignition switch.
2. Drain oil from planetary wheel drive/brake assembly.
CAUTION
When removing front wheel, use correct jacks
and supports. Make suremachine is parked ona
solid, level surface such as a concrete floor.
Prior to raising machine, remove any attach-
ments that may interfere with the safe and prop-
er raising of the machine. Alwayschockorblock
wheels. Use jack stands to support the raised
machine. If the machine is not properly sup-
ported by jack stands,the machine may moveor
fall, which may result in personal injury.
3. Chock rear wheels and jack up front of machine (see
Jacking Instructions in Chapter 1 -- Safety). Support ma-
chine with suitable jack stands.
4. Remove front wheel assembly.
5. Remove four (4) flange head screws that secure
brake assembly to planetary assembly (see Brake As-
sembly Removal in this Chapter).
6. Support hydraulic wheel motor to prevent it from fal-
ling. Remove two (2) cap screws that secure wheel mo-
tor to planetary assembly.
7. Supportplanetary assembly to prevent it fromfalling.
Loosen and remove flange head screws that secure
planetary assembly to frame. Remove planetary as-
sembly from machine.
Installation (Fig. 6)
1. Inspectgasket between brake and planetary assem-
blies. Replace as needed.
2. Position planetary assembly to machine. Install
flange head screws that secure planetary assembly to
frame. Torque screws from 75 to 85 ft--lb (101 to 115
N--m).
3. Secure brake assembly to planetary assembly with
four (4) flangeheadscrews(seeBrakeAssembly Instal-
lation inthisChapter).Torque screws from 75to85ft--lb
(101 to 115 N--m).
4. Securehydraulicwheelmotor to planetary assembly
with two(2)capscrews. Torque screws from 75 to 85ft--
lb (101 to 115 N--m).
5. Install wheel assembly.
WARNING
Failure to maintain proper torque could result in
failure or loss ofwheeland may result inperson-
al injury.
6. Lower machine from jack stands. Torque lug nuts
from 85 to 100 ft--lb (115 to 135 N--m).
7. Make sure drain plug is installed in bottom of brake
assembly (Fig. 7). Fill planetary wheel drive/brake as-
sembly with SAE 85W--140 gear lube. Capacity is
approximately 16 fl. oz. (0.47 l) per wheel.
8. Check for proper brake operation.
1. Brake housing
2. Wheel motor cap screw
3. Brake flange screw
4. Planetary flange screw
5. Brake drain plug
