UP position) and the brake is applied.
Put
blocks on both sides (front and back) of the

block on each side (front and back) of the load
wheels to prevent movement of the lift truck.
NOTE:
The recommended maintenance and repairs
for the steering pump motor are covered in the sec-
tion DC Motor Maintenance 620 SRM 294.
1. Disconnect the battery.
2. Identify and tag the power cables on the termi-
nals of the motor for correct connection during
installation. Disconnect the cables from the mo-
tor.
3. Identify and tag the hydraulic hoses at the pump
for the correct connection during installation.
Disconnect the hoses, and install caps on the
hoses and plug the ports to keep dirt out of the
system.

The motor and pump assembly have a weight
of approximately 27 kg (60 lb). The steering
pump motor has ceramic permanent magnets.
Do not let the motor fall. The magnets can be
damaged.
4. Remove the four capscrews, lockwashers, brack-
ets, and rubber channel mounts. See Figure 7.
Remove the motor, pump, and bracket from the
lift truck frame.
5. Check the brushes. See the sections Periodic
Maintenance 8000 SRM 970 and DC Motor
Repair 620 SRM 294 for additional information
for inspection of the brushes and commutator.
6. If the motor must be disassembled for cleaning or
repairs, remove the pump so a new oil seal can
be installed in the motor. Remove the mount-
ing bracket from the motor. Make matchmarks
for alignment on the pump mount flange and the
motor housing. Make matchmarks for alignment
of the parts of the motor housing. These marks
are necessary to assemble the motor and pump
