Assembly of the Inlet and Throttle
1. Insert the Throttle Valve Plunger (8) into the Motor
Housing (5).
2. Position the Throttle Lever (6) on the Motor Housing
and using an arbor press, press the Throttle Lever Pin
(7) into the Housing and Lever. The Lever will retain
the Plunger in the Housing.
3. If the Throttle Valve Cartridge Case (4D) was
removed, lubricate the outside and the throttle stem
end of the Case with O–ring lubricant. Using a
wooden dowel, push the Case, open end trailing, into
the Motor Housing.
4. If the Throttle Valve Seat (4C) was removed, use a
5/8" wooden dowel with a flat end to push the Seat
into the Motor Housing.
5. Push the small end of the Throttle Valve Spring (4A)
onto the end of the Throttle Valve (4B) 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.
6. 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.
7. 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.
8. Thread the Inlet Assembly into the Housing and
tighten it between 13 to 15 ft–lb (18 to 20 Nm)
torque.
Assembly of the Motor
Steps common to ALL models
1. If the Rear Rotor Bearing (9) was removed, stand the
Rotor (12) 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 (11) in the
groove on the hub of the Rotor.
3. Install the Front End Plate (14), counterbored end
trailing, onto the threaded hub of the Rotor. Using
finger pressure, press the Front Seal Cup Assembly
(16), felt end trailing, onto the end of the Front End
Plate Spacer (15) that is opposite the large internal
bevel. Continue pressing until the felt end is flush
with the end of the Spacer. Lubricate 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.

10. Wipe each Vane (13) with a light film of oil and insert
27
Before performing the next step, be aware that the
Front Rotor Bearing is a flush ground bearing and
must be installed in a specific manner. The end of
the Bearing with a black stain or hash marks must
be away from the Spacer.
4. Stand the Rotor on the table of an arbor press with the
threaded end upward and press the Front Rotor
Bearing (17) onto the hub of the Rotor.
5. Grasp the assembled Rotor in copper–covered or
leather–covered vise jaws with the threaded rotor hub
upward.
6. For TD models, using finger pressure, press the Front
Seal Cup Assembly (39A or 47A), felt end trailing,
onto the rotor end of the Collet Body (39)or Wheel
Adapter (47). Continue pressing until the felt end is
flush with the end of the Collet Body or Wheel
Adapter. Lubricate the felt with Ingersoll–Rand No.
50 Oil.
7. If the Front Arbor Bearing (27) must be replaced on a
Model TXD, proceed as follows before assembling
the motor:
a. Place the Clamp Sleeve (23) on the table of an
arbor press and install the large end of the Arbor
Housing (25) on the Clamp Sleeve.
b. Slide the Front Arbor Bearing onto the threaded
hub of the Arbor (24) 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 but keep the parts together so that the
same parts are installed together. Do not mix and
match Arbors with Bearings and Housings.
8. Thread the Collet Body and Seal Assembly (for TD
models), Arbor (24) (for TXD models) or the Arbor
Bearing Nut (31), Retainer end leading, (for TX
models) onto the Rotor and using a torque wrench,
tighten the Collet Body, Arbor or Arbor Bearing Nut
between 14 and 19 ft–lb (19 and 26 Nm) torque.
9. Inject approximately 3/4 cc of Ingersoll–Rand No. 68
Grease into the small recess at the bottom of the
motor housing bore. Drop the two Rear Rotor
Bearing Spacers (10) into the bottom of the motor
housing bore.
a Vane into each vane slot in the Rotor.
