Illustration 9 g00651967
Install O-ring seal (21) and backup ring (22) on piston guide (19), as shown.
Illustration 10 g00510356
Place the body of the travel motor in a vertical position.
Apply clean hydraulic oil on five friction plates (20) and the four steel plates. Install the plates in alternating order in the body of the travel motor. Start with a friction plate and end with a friction plate.
Install piston guide (19) in the body of the travel motor until the piston guide contacts the counterbore in the body of the travel motor.
Illustration 11 g00878297Note: Make sure that brake piston (14) is thoroughly clean and free of dirt and debris.
Install O-ring seal (16). Install backup ring (15).
Install O-ring seal (17). Install backup ring (18).
Apply a thin coat of hydraulic oil on the surfaces of piston (14) which contact the body of the travel motor. Install piston (14) in the body of the travel motor by hand. It may be necessary to use a soft faced hammer to seat the piston correctly.

Apply a thin coat of 9S-3263 Thread Lock Compound on the threads of the two check valves. Install the check valves in the head.
Install seat (7), poppet (8) and spring (9) in the head at Location (X).
Install O-ring seal (6) in the head, as shown.
Install bearing (3) in the head until the bearing contacts the counterbore in the cover.
Apply 1U-6396 O-Ring Assembly Compound on port plate (4). Install the port plate in the port plate's original position on the motor cover.
Use a shim or shims (5) so that the following requirements are met. Note: During the following checks, turn the travel motor output shaft in a clockwise direction.
The travel motor output shaft does not rotate with an applied torque of 440 N m (325 lb ft) or more with the parking brake release port open.
The travel motor output shaft rotates with an applied torque of 29 N m (21 lb ft) or less when the parking brake release port is pressurized to 780 kPa (115 psi) with both the inlet port and the outlet port open to the hydraulic oil tank. Note: It may be necessary to remove head (2) several times in order to determine the correct thickness of shim or shims (5) that are used to adjust the rolling torque of the travel motor output shaft.
Apply a thin layer of 5P-0960 Molybdenum Grease on shim or
