CAUTION
When changing attachments, tires, or perform-
ing other service, use correct blocks, hoists,
and jacks. 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
proper raising of the machine. Always chock or
block wheels. Use jack stands or solid wood
blocks to support the raised machine. If the ma-
chine is not properly supported by blocks or
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 jack stands or solid wood blocks.
4. Remove wheel assembly.
5. Remove hydraulic wheel motor (see Front Wheel
Motors in Service and Repairs section of Chapter 4 −
Hydraulic System).
6. Disconnect brake cable from pull rod on brake.
7. Remove flange head capscrews (5) securing brake
assembly to frame; be careful not to drop splined brake
shaft as brake assembly is removed.
8. Remove splined brake shaft.
9. Complete brake inspection and repair.
Install Brake Assembly (Fig. 1)
1. Install splined brake shaft into brake assembly.
Note: The stepped end of the splined brake shaft must
be aligned toward the hydraulic wheel motor (Fig. 2).
2. Install brake assembly onto frame, aligning splined
brake shaft with input shaft on planetary wheel drive.
3. Install flange head screws (5) to secure brake as-
sembly to frame. Tighten screws in a crossing pattern to
a torque from 75 to 85 ft−lb (101 to 115 N−m).
4. Install brake cable to pull rod on brake assembly.
Brake cable end should be completely threaded onto
pull rod.
5. Install new o−ring on hydraulic wheel motor. Install
wheel motor and torque capscrews from 75 to 85 ft−lb
(101 to 115 N−m).

Failure to maintain proper torque could result
in failure or loss of wheel and may result in
personal injury.
6. Install wheel assembly. Torque lug nuts from 85 to
100 ft−lb (115 to 135 N−m).
7. Lower machine to ground.
8. Make sure drain plug is installed in bottom of brake
assembly (Fig. 3). Fill planetary wheel drive/brake as-
sembly with SAE 85W−140 gear lube (see Operator's
