3.14 SWING MOTOR
Cleanliness is extremely important when repairing hydrau-
lic motors. Work in a clean area. Before disconnecting the
hydraulic lines, clean the port area of the motor. Before
disassembly, drain 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.
Disassembly
1. Clamp the motor in a vise so the shaft is vertical and
the end cap is on the top. Clamp on the mounting
flange, use just enough clamping force to hold the
motor securely. Protect the mounting flange with soft
vise jaws.
2. Remove the 7 cap screws from the end cap and dis-
assemble the motor as shown.
3. Unclamp the motor and remove the output shaft,
thrust needle bearing, and thrust bearing race.
4. Clamp the motor in a vise so the mounting flange is
on top.Clamp across the port area.
Do not clamp
on motor housing.
Use just enough clamping force
to hold the motor securely.
5. Remove the four cap screws that hold the mounting
flange to the motor housing.
