Disassembly
1. Place the motor in a vice and clamp across the edges of
the flange Figure 4-12 with the output shaft facing down.
When clamping use protective devices on the jaws, such
as soft jaws, pieces of rubber or wood.
NOTE: Although not all drawings show the motor in a vice,
it is recommended that you keep the motor in the
vice during disassembly and assembly. Follow the
clamping procedure explained in Step 1.
2. Remove seven capscrews (19) Figure 4-13 and seal
washers (18).
3. Remove end cap (17). Remove and discard seal (13)
from the end cap.
4. Remove gerotor (16). Remove and discard seal (13)
from the gerotor.
5. Remove drive spacer, if applicable.
6. Remove drive shaft (14).
7. Remove spacer plate (15).
8. Remove seal 13 from housing (10).

10. Remove needle thrust bearing (8) from shaft or housing.
11. Reposition the motor in the vice. Clamp across ports
Figure 4-14. DO NOT clamp on housing. Excessive
clamping pressure on side of housing causes distortion.
CAUTION
Cleanliness is extremely important when repairing the
swing motor. Work in a clean area. Plug the ports then use
a wire brush to remove foreign material and debris from
around the external joints of the motor. Check the shaft
and key slot, remove all nicks, burrs or sharp edges that
might damage seals during installation. Before starting
the disassembly procedures, drain any remaining oil from
inside the motor.
