or copper–covered vise jaws with the Back Cap (2)
upward.
2. Using a hex wrench, unscrew and remove the Cap
Screws (21) and Lock Washers (22).
3. Lift the Back Cap off the Housing. Remove the Seal
(3) from the inside of the Back Cap.
4. Remove the Clamp Washer (5) from the Housing.
5. Remove the assembled motor from the vise jaws and
using a plastic hammer, tap the splined shaft of the
Rotor (8) to dislodge the Rotor from the Front Rotor
Bearing (12).
6. Lift the Motor Housing off the Rotor, Rear End Plate
(6) and Rear Rotor Bearing (7). The Rear End Plate
and Rear Rotor Bearing will remain together as a
unit.
7. Remove the Vanes (9) from the Rotor.
8. Pull the Rear End Plate off the Rotor.
9. Open a set of vise jaws wide enough to clear the hub
of the Rear End Plate and sharply rap the hub end of
the End Plate on the top of the jaws to dislodge the
Rear Rotor Bearing.
10. Remove the Cylinder Dowel (13) and lay the Motor
Housing on top of the vise jaws with the Front Rotor
Bearing (12) downward between the jaws. Using a
soft drift pin, tap the Bearing out of the Housing.
11. To remove the Cylinder (10) and Front End Plate
(11), thread four 1/4”–20 thread socket head cap
screws that are at least 3” (75 mm) long into the Back
Cap end of the Housing. Grasping the Housing with
the installed screws downward, sharply strike the
heads of the screws on a sturdy table to dislodge the
Cylinder. The Cylinder should drop out of the Housing after a few impacts. If it does not, proceed as follows:
The following procedure requires the use of heat.
Take all precautions necessary to prevent being
burned.
