8. Clean the hydraulic tube ends and fittings on the wheel motor to prevent
contaminants from entering into the hydraulic system.
9. Label and remove the hydraulic tubes from the fittings on the wheel motor.
Allow the tubes to drain into a suitable container.
10. Install clean caps and plugs on the hydraulic tubes and fittings to prevent
system contamination.
11. Record the wheel motor location (mark the wheel motor) prior to removal.
12. Record the location of the spring clip (item 16) for assembly purposes.
13. Support the wheel motor and remove the fasteners, spring clip, and brake
adapter from the machine.
14. Remove the wheel motor from the machine.
15. If the hydraulic fittings are to be removed from the wheel motor, mark the
fitting orientation for assembly purposes. Remove the fittings from the wheel
motor and discard the O-rings from the fittings.
Installing the Front Wheel Motors
Because of the internal differences in the wheel motors, do not
interchange the wheel motors on the machine (e.g., do not put the
right motor on the left side of the machine). If necessary, use the
traction unit Parts Catalog and part number on the wheel motor to
identify the right and left motors. The left side wheel motors are
identified with a yellow dot on the motor housing near the B port.
Refer to Figure 58 for this procedure.
1. If the hydraulic fittings were removed from the wheel motor, lubricate and
install new O-rings to the fittings. Align and install the fittings into the wheel
motor ports; refer to
O-Ring Fittings) (page
2. Fit the wheel motor and brake adapter to the frame and install the previously
removed fasteners.
3. Install the spring clip and tighten the fasteners from 108 to 122 N·m (80
to 100 ft-lb).
4. Remove the caps and plugs then connect the hydraulic tubes to the wheel
motor fittings; refer to
Seal Fitting) (page
5. Install the brake plate assembly with the previously removed fasteners.
Before installing the wheel hub, clean the tapers of the wheel hub
and wheel motor shaft. Ensure that the tapers are free of grease,
oil, rust, and dirt. Do not use anti-seize lubricant, when you install
the wheel hub.
Do not use the locknut previously removed to attach the wheel hub
to the wheel motor.
