Cleanliness is extremely important when repairing hydraulic
motors. Work in a clean area. Before disconnecting the
hydraulic lines, clean the port area of the motor. Before
disassembly, drain the oil from the motor. Then plug the ports
and thoroughly clean the exterior of the motor. Check the
output shaft, remove any burrs, nicks, or sharp edges.
1 Clamp the motor in a vise so the shaft is vertical and the end
cap is on top. Clamp on the mounting flange using just enough
clamping force to hold the motor securely. Protect the mount-
ing flange with soft vise jaws.
2 Remove the seven cap screws from the end cap and disas-
semble the motor as shown in Figure 1. Do not disassemble
the Geroler.
3 Un-clamp the motor and remove the output shaft, thrust
needle bearing, and thrust bearing race (see Figure 2).
4 Clamp the motor in a vise so the mounting flange is on top.
Clamp across the port area. Do not clamp on the motor
housing. Use just enough clamping force to hold the motor
securely.
