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 sure machine is parked on a
solid, level surface such as a concrete floor.
Prior to raising machine, remove any attachments
that may interfere with the safe and proper
raising of the machine. Always chock or block
wheels. Use jack stands to support the raised
machine. If the machine is not properly supported
by jack stands, the machine may move or
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 machine
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 Assembly
Removal in this Chapter).
6. Support hydraulic wheel motor to prevent it from falling.
Remove two (2) cap screws that secure wheel motor
to planetary assembly.
7. Support planetary assembly to prevent it from falling.
Loosen and remove flange head screws that secure
planetary assembly to frame. Remove planetary assembly
from machine.
Installation (Fig. 6)
1. Inspect gasket between brake and planetary assemblies.
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) flange head screws (see Brake Assembly Installation
in this Chapter). Torque screws from 75 to 85 ft -lb
(101 to 115 N -m).
4. Secure hydraulic wheel motor to planetary assembly
with two (2) cap screws. Torque screws from 75 to 85 ft -
lb (101 to 115 N -m).
5. Install wheel assembly.
WARNING
Failure to maintain proper torque could result in
failure or loss of wheel and may result in personal
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 assembly
with SAE 85W--140 gear lube. Capacity is
approximately 16 fl. oz. (0.47 l) per wheel.
8. Check for proper brake operation.
