Assembly of the Inlet and Throttle
1. Insert the Throttle Valve Plunger (11) into the Motor
Housing (8).
2. Position the Throttle Lever (9) on the Motor Housing
and using an arbor press, press the Throttle Lever Pin
(10) into the Housing and Lever. The Lever will
retain the Plunger in the Housing.
3. If the Throttle Valve Seat (7) was removed, use a 5/8"
wooden dowel with a flat end to push the Seat into the
Motor Housing.
4. Push the small end of the Throttle Valve Spring (5)
onto the end of the Throttle Valve (6) with the short
stem until the Spring snaps into position around the
hub and remains there. Install the dish end of the
Throttle Valve Spring Seat (4) onto the large end of
the Throttle Valve Spring.
5. Holding the Housing with the Lever downward, make
sure the Plunger is out of the way and insert the
assembled Throttle Valve, long stem end leading, into
the housing recess.
6. Push the Inlet Screen (2), closed end leading, into the
Inlet Assembly (1). After moistening a new Inlet Seal
(3) with O–ring lubricant and being careful not to
nick the Seal on the threads of the Inlet, install the
Seal on the Inlet.
7. Thread the Inlet Assembly into the Housing and
tighten it between 20 to 25 ft–lb (27 to 34 Nm)
torque.
Assembly of the Motor
Steps common to ALL models
1. If the Rear Rotor Bearing (12) was removed, stand the
Rotor (15) upright on the table of an arbor press with
the threaded end downward. Make sure the threaded
end passes through a hole drilled in a block so that the
Rotor rests against the large rotor body. Press the Rear
Rotor Bearing onto the hub of the Rotor.
2. Install the Rear Rotor Bearing Retainer (14) in the
groove on the hub of the Rotor.
3. Install the Front End Plate (17), counterbored end
trailing, onto the threaded hub of the Rotor. Using
finger pressure, press the Front Seal Cup Assembly
(19), felt end trailing, onto the end of the Front End
Plate Spacer (18) that is opposite the the large internal
bevel. Continue pressing until the felt end is flush
with the end of the Spacer. Saturate the felt with
Ingersoll–Rand No. 50 Oil. Place the assembled
Spacer, Seal Assembly trailing, onto the threaded hub
of the Rotor. Make sure the Seal Assembly enters the
recess in the Front End Plate.

Model HXD, proceed as follows before assembling
the motor:
a. Place the Clamp Sleeve (28) on the table of an
arbor press and install the large end of the Arbor
Housing (30) on the Clamp Sleeve.
b. Slide the Front Arbor Bearing onto the threaded
hub of the Arbor (29) and insert the Arbor, bearing
end trailing, into the Housing. Make certain the
end of the Arbor rests on the arbor press table and
the Bearing is aligned with the bore in the
Housing.
c. Install the small piece of the LE2–950 Bearing
Inserting Tool over the Arbor and press the
Bearing into the Housing until it stops against the
shoulder of the Arbor.
d. Remove the Arbor from the Housing and Bearing
