FT-0957 Positioning Gp (Axle Repair)     4    Start By:
Remove the fixed axle. Refer to Disassembly and Assembly, "Fixed Axle (Front) - Remove".
Remove the oscillating axle. Refer to Disassembly and Assembly, "Oscillating Axle (Rear) - Remove".Note: The axle housing assemblies that are used in the front fixed axle and in the rear oscillating axle are similar. Therefore, both axle housing assemblies can be disassembled in the same manner.

Install the axle assembly on Tooling (B) in a vertical position.Note: Carefully remove the axle housing assembly. Part of the wear gauge pin will remain in the axle housing assembly. The pin will remain in the axle housing assembly. The spring and the piston will remain in the differential housing.
Attach Tooling (A) and a suitable hoist to the rim of the axle shaft. Remove bolts (1) that secure axle housing assembly (2) to the differential housing. Use the hoist in order to carefully remove the axle housing assembly. The weight of axle housing assembly (2) is 365 kg (800 lb).

Remove reaction plate (4) .
Remove two springs (5) .
If necessary, remove two dowels (6) and dowel (12) .Note: Pin (9) , O-ring seal (8) , and hollow dowel (7) will remain in the axle housing assembly.
Remove spring (10) and cup (11) .
Remove friction disc (13) , and reaction plate (14) .
Personal injury can result from air pressure against the brake piston.The brake piston can come out of the differential housing assembly with force when applying air pressure.To prevent possible personal injury, the brake piston must be retained in the differential housing assembly when applying air pressure.
Retain brake piston (15) . Apply shop air pressure to the fitting for the brake line. The correct air pressure is approximately 525 kPa (75 psi). Brake piston (15) will move out of the differential housing.
Remove seal (16) and seal (17) from the differential housing.
Illustration 4 g00451337
Remove bolt (19) and plug (18) from the flange face of the axle housing. Remove pin (9) , O-ring seal (8) , and dowel (7) from axle housing (2) .
Repeat Steps 1 through 11 for the remaining service brake.
