26.4. Remove the wheel from the wheel motor to be
replaced using a 3/4” wrench. See Figure 26.4.
26.5. Release the parking brake.
26.6. Disconnect the brake rod from the brake arm.
26.7. Match mark and disconnect the hydraulic hoses
from the wheel motor using a 7/8” wrench and a
1” wrench. See Figure 26.7.
• Catch escaping fluid in a drain pan.
• Check the fluid that comes out of the motor for
debris.
• Cap the fittings on the motor to prevent fluid
spillage on removal, and plug the ends of the
hoses to prevent fluid contamination.

26.8. Unbolt the wheel motor from the frame using a 3/
8” allen wrench and a 3/4” wrench, and carefully
remove it. See Figure 26.8.
26.9. On the bench:
• Drain any remaining fluid from the motor.
• Make a visual comparison to confirm that the
replacement motor is suitable.
• Transfer any necessary fittings or components to
the new motor.
26.10.If there is a possibility of fluid contamination,
either as a cause of or a result of the pump (or
motor) failure:
• Replace the filter.
• Drain and properly dispose-of the remainder of
the fluid in the system.
• Remove and clean or replace the hoses con-
nected to the “A” and “B” ports of the pump.
• Follow break-in procedure; initial fluid change
after 50 hrs. of operation.
NOTE: If hoses are cleaned with parts-washer
solvent, follow-up with hot soapy water and hot
water rinse. Dry thoroughly before reinstallation.
The parts washer solvent is an astringent that
will remove any traces of contaminated fluid.
The soapy water is a surfactant that will remove
any grit from the lining of the hose and flush
away any remnants of solvent. Residual solvent
will very effectively thin-out hydraulic drive sys-
tem fluid, contributing to performance problems
and premature component failure.
