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 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 as- sembly.

7.Support brake assembly to prevent it from falling.

8.Remove four (4) flange head screws (item 9) secur- ing brake assembly to machine. Remove brake assem- bly taking care to not drop splined brake coupler as brake assembly is removed.

9.Remove splined brake coupler.

10.Complete brake inspection and repair (see Brake In- spection and Repair in this section).

Installation (Fig. 1)

1.Slide splined brake coupler into brake assembly. NOTE: The stepped end of the coupler must be installed toward the hydraulic wheel motor (Fig. 2).

2.Position brake assembly to frame, aligning splined brake coupler with input shaft on planetary wheel drive.

3.Install four (4) flange head screws to secure brake assembly to frame. Torque screws in a crossing pattern 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 cap screws from 75 to 85 ft--lb (101 to 115 N--m).

6.Install wheel assembly.

WARNING

Failure to maintain proper torque could result in failure or loss of wheel and may result in person- al injury.

7.Lower machine to ground. Torque lug nuts from 85 to 100 ft--lb (115 to 135 N--m).

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. Capacity is approximately 16 fl. oz. (0.47 liters) per wheel.

9.Check and adjust brake cables for proper brake op- eration. If necessary, adjust brake cable jam nuts at frame bracket so that pull rod jam nut is positioned from 0.470” to 0.530” (12.0 to 13.4 mm) from brake casting surface when brakes are disengaged (Fig. 4).
