Apply the air pressure at orifice (X). Use Tooling (G) in order to turn the output shaft when the parking brake release port is pressurized to 780 kPa (115 psi). Perform this procedure with the inlet port and the outlet port open to the hydraulic oil tank. The travel motor output shaft rotates with an applied torque of 29 N m (21 lb ft) or less. Note: It may be necessary to remove head (8) several times in order to determine the correct thickness of shim or shims (9) that are used to adjust the rolling torque of the travel motor output shaft.
Apply a thin layer of Tooling (H) on shim or shims (9). Install the shim or shims on the head. The grease will hold the shim or shims in place during the installation of the head. Install the head on the body of the travel motor.
