15. Stand the Rotor (30) on the table of an arbor press. It
should be upright on a flat metal plate having a clear-
ance hole for the shaft. The shaft with the hex must
be upward.
16. Place a 0.001" (0.025 mm) shim on the upward sur-
face of the large portion of the rotor body. Using a
piece of tubing that contacts the inner ring of the
bearing, press the Front Rotor Bearing and Front End
Plate, End Plate leading, onto the shaft of the Rotor
until the End Plate contacts the shim. Remove the
shim. (Refer to Dwg. TPD1275)

17. Coat each Vane (31) with a thin film of oil and insert
a Vane into each of the rotor vane slots with the
straight edge of the Vane outward.
18. Install the Cylinder (27) over the Vanes and Rotor
with the end of the Cylinder having the Alignment
Pin (29) in the middle of the four holes positioned
toward the Front End Plate. (Refer to Dwg.
TPD1276). Make certain the Pin enters the hole in the
face of the Front End Plate.
19. Place the Rear End Plate and Bearing against the face
of the Cylinder, Bearing end trailing. Make certain
the Rear End Plate Alignment Pin (28) protrudes
through hole in the End Plate.
20. Apply a thin film of Ingersoll–Rand No. 67 Grease to
the face of the Rear End Plate and place the Rear End
Plate Spacer (24) against the end plate face. Make
certain the Alignment Pin enters the hole in the

21. Insert the assembly, End Plate Spacer leading, into
the Motor Housing making sure the Alignment Pin
protruding through the Spacer enters the proper hole
in the Reverse Valve. It may be necessary to tap the
assembly into position with a brass or plastic
hammer. (Refer to Dwg. TPD1279)
22. Grasp the handle of the Motor Housing in vise jaws
with the rotor shaft upward. Thread the Front End
Plate Spacer (35) into the Housing and using the end
plate spacer spanner, tighten the Spacer to 12 ft–lb
(16 Nm) torque. This is a left–hand thread; rotate
the wrench counterclockwise to tighten. (Refer to
Dwg. TPD1280).
