Disassembly of the Rear Wheel Drive Motor
Cleanliness is extremely important when repairing a hy-
draulic motor. Work in a clean area. Before disconnect-
ing the lines, clean the port area of the motor thoroughly.
Use a wire brush to remove foreign material and debris
from around the exterior joints of the motor. Check the
shaft and keyslot, remove all nicks, burrs or sharp edges
that might damage the bearing housing seals when
installing the shaft and bearing assembly. Before start-
ing the disassembly procedures, drain the oil from inside
the motor.
