END PLATE SPACER SPANNER
3. Reposition the Motor Housing in the vise jaws so that
the vise jaws grip the end of the rotor shaft and the
handle grip of the Housing is downward. Tap the edges
of the Housing surrounding the motor bore with a
plastic hammer to separate the Housing from the
motor. (Refer to Dwg. TPD1298.)
4. Remove the motor from the vise jaws and remove the
Front End Plate (25), Front Rotor Bearing (27),
Cylinder Assembly (20) and Vanes (24) from the
Rotor.
5. Remove the Rear End Plate Spacer (17) from the
Motor Housing or the Rear End Plate (18).
6. On the table of an arbor press, support the Rear End
Plate with blocks as close to the Rotor as possible
and press the Rotor out of the Rear End Plate and Rear
Rotor Bearing (19).
In the following step, do not enlarge or damage the
shaft hole in the End Plate when removing the
Bearing.
7. To remove the Rear Rotor Bearing from the Rear End
Plate, use a small drift or pin punch through the central

ASSEMBLY
General Instructions
1. Always press on the inner ring of a ball–type bearing
when installing the bearing on a shaft.
2. Always press on the outer ring of a ball–type bearing
when pressing the bearing into a bearing recess.
3. When grasping a tool or part in a vise, always use
leather–covered or copper–covered vise jaws to protect
the surface of the part and help prevent distortion. This
is particularly true of threaded members and housings.
4. Except for bearings and mechanism parts, always
clean every part and wipe every part with a thin film of
oil before installation.
5. Wipe a thin film of mechanism fluid on all internal
mechanism components before installing them in the
mechanism.
6. Apply a film of o–ring lubricant to every o–ring before
installation.
