Disassembly
Cleanliness is extremely important when repairing a
hydraulic motor. Work in a clean area. Before disconnecting
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
key slot, remove all nicks, burrs or sharp edges that might
damage the bearing housing seals when installing the shaft
and bearing assembly. Before starting the disassembly
procedures, drain the oil from inside the motor.

1. Place the motor in a vise with the output shaft down.
Clamp across the mounting flange of the motor not
the housing. Excessive clamping pressure will cause
distortion. When clamping, use some protective
device on the vise, such as special soft jaws, pieces
of hard rubber or board.
Although not all drawings show the motor in a vise, we
recommend that you keep the motor in the vise during
disassembly and reassembly. Follow the clamping
procedures explained throughout the manual
