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 attach- ments that may interfere with the safe and prop- er raising of the machine. Always chock or block wheels. Use jack stands to support the raised machine. If the machine is not properly sup- ported 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 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.Support planetary assembly to prevent it from falling. Loosen and remove flange head screws that secure planetary assembly to frame. Remove planetary as- sembly from machine.

Installation (Fig. 6)

1.Inspect gasket 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) flange head screws (see Brake Assembly Instal- lation 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 person- 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.
