10. Remove the Roll Pin from the Shaft (See Figure 13).
11. Inspect the Motor End Plate, Body, and Gerotor
Housing for signs of wear and/or gouging. If signs of
wear or gouging are present in both the Motor End
Plate and Body, the Hydraulic Motor is not reparable.
If gouging has occurred in the Motor End Plate,
Body, or Gerotor Housing, the part that is worn must
be replaced. If the Gerotor Housing is damaged, the
Gerotor parts must also be replaced.
12. While the hydraulic Motor is disassembled, clean all
parts in a solvent bath.
Removing the Shaft Assembly from the Motor Body
1. Remove the Rubber Slinger Ring from the Motor
Shaft (See Figure 14).
Special attention should be exercised when working
with retaining rings. Always wear safety goggles
when working with spring or tension loaded
fasteners or devices.
2. Remove the Internal Retaining Ring securing the
Ball Bearing and Shaft Assembly to the Motor Body
(See Figure 14).
If the Ball Bearing is binding against the internal
retaining ring so that the internal retaining ring
cannot be easily removed, place the motor body on
the arbor press support fixture with the ball bearing
side up. Gently press against the shaft to relieve
pressure of the ball bearing pressing against the
internal retaining ring.
3. Place the body in the support fixture and position it
on the arbor press; then press the Shaft Assembly
out of the Motor Body (See Figure 15).
