Removal (Fig. 6)<br />
1. Park machine on a level surface, lower cutting deck,<br />
stop engine, engage parking brake and remove key<br />
from the ignition switch.<br />
2. Drain oil from planetary wheel drive/brake assembly.<br />
CAUTION<br />
When removing front wheel, use correct jacks<br />
and supports. Make sure machine is parked on a<br />
solid, level surface such as a concrete floor.<br />
Prior to raising machine, remove any attachments<br />
that may interfere with the safe and proper<br />
raising of the machine. Always chock or block<br />
wheels. Use jack stands to support the raised<br />
machine. If the machine is not properly supported<br />
by jack stands, the machine may move or<br />
fall, which may result in personal injury.<br />
3. Chock rear wheels and jack up front of machine (see<br />
Jacking Instructions in Chapter 1 -- Safety). Support machine<br />
with suitable jack stands.<br />
4. Remove front wheel assembly.<br />
5. Remove four (4) flange head screws that secure<br />
brake assembly to planetary assembly (see Brake Assembly<br />
Removal in this Chapter).<br />
6. Support hydraulic wheel motor to prevent it from falling.<br />
Remove two (2) cap screws that secure wheel motor<br />
to planetary assembly.<br />
7. Support planetary assembly to prevent it from falling.<br />
Loosen and remove flange head screws that secure<br />
planetary assembly to frame. Remove planetary assembly<br />
from machine.<br />
Installation (Fig. 6)<br />
1. Inspect gasket between brake and planetary assemblies.<br />
Replace as needed.<br />
2. Position planetary assembly to machine. Install<br />
flange head screws that secure planetary assembly to<br />
frame. Torque screws from 75 to 85 ft -lb (101 to 115<br />
N-m).<br />
3. Secure brake assembly to planetary assembly with<br />
four (4) flange head screws (see Brake Assembly Installation<br />
in this Chapter). Torque screws from 75 to 85 ft -lb<br />
(101 to 115 N -m).<br />
4. Secure hydraulic wheel motor to planetary assembly<br />
with two (2) cap screws. Torque screws from 75 to 85 ft -<br />
lb (101 to 115 N -m).<br />
5. Install wheel assembly.<br />
WARNING<br />
Failure to maintain proper torque could result in<br />
failure or loss of wheel and may result in personal<br />
injury.<br />
6. Lower machine from jack stands. Torque lug nuts<br />
from 85 to 100 ft -lb (115 to 135 N -m).<br />
7. Make sure drain plug is installed in bottom of brake<br />
assembly (Fig. 7). Fill planetary wheel drive/brake assembly<br />
with SAE 85W--140 gear lube. Capacity is<br />
approximately 16 fl. oz. (0.47 l) per wheel.<br />
8. Check for proper brake operation.<br />
