Assembly of the Throttle and Inlet
Thoroughly clean and lubricate all Throttle Valve
components before assembling the tool. Lubricate
with Ingersoll–Rand Light Oil No. 10.
1. Grasp the Dead Handle in leather–covered or copper–
covered vise jaws with the live air handle upward.
2. Assemble the Valve Seat Support parts.
3. Insert the Support Assembly (7) into the handle, large
diameter first. Locate a punch on the flat of the
screw head and tap it with a hammer until the Assem-
bly is firmly seated.
4. Apply O–ring lubricant to the Seals (3) or (3 and 4).
Fit the seals to the Throttle Valve (2) and push the
assembly, small diameter first, into the handle until it
seats firmly.
If Lever Assembly being serviced does not have
the window–type lever, install a complete new
Lever Assembly.
5. Assemble the Lever Assembly (15) as illustrated
below.
Locking Lever Assembly
6. Align the holes in the Lever Assembly with the slots
in the Cylinder Case. With a soft face hammer, tap
the Throttle Lever Pin (14) through the Lever Assem-
bly. File off any sharp edges. Operate the mechanism
internally by hand to assure operation.
7. Insert the Throttle Valve Spring (6), small end first.
8. Clean the face of the Inlet Bushing (5) and the Inlet
Bushing Screen (5A) using a suitable cleaning solu-
tion, and dry them. Insert the screen and bushing in
the end of the Cylinder Case by grasping the flats
with a wrench. Tighten the Bushing between 35 and
45 ft–lb. (47 and 61 Nm) torque.

Assembly of the Motor
1. Using an arbor press against the inner race of the
bearing, install the Front Rotor Bearing (30) onto the
Arbor (29).
2. Inspect the Front End Plate (31) for nicks or burrs.
Press the arbor bearing into the front end plate.
3. With the Arbor held firmly in vise jaws, place the
Rotor Key (33) in the slot of the Rotor (34).
The Rotor should slip fit over the Arbor. If tight-
ness is detected, lightly polish one long side of the
Key using fine emery cloth on a hard, flat surface.
Replace the Key with the polished side toward the
Arbor.
4. The Rotor is counter–bored on one end. Place that
end over the Arbor. Apply a light film of Ingersoll–
Rand No. 50 Oil to each Vane (35) and insert one
vane, straight end out, into each slot in the Rotor. If
any new Vanes are required, replace the entire set.
5. Place the Cylinder Assembly (36) over the Rotor
matching the End Plate Dowel (short dowel) (37) to
the alignment hole in the Front End Plate (31).
If the Controller Assembly (42) needs to be re-
placed, you must also replace the Rotor Bearing
Seal Assembly (43) which consists of the Rear Ro-
tor Bearing and Rotor Bearing Seal. If either the
Rear Rotor Bearing or Rotor Bearing Seal needs
to be replaced, both must be replaced with a new
Bearing and Seal. Do not mix old and new parts.
6. Clean the Rotor Bearing Seal (43) and measure the
outside diameter and large inside diameter. If the
outside diameter is worn to 1.1764" (29.88/mm) or
smaller, and/or the large inside diameter is worn to
0.9103: (23.122 mm) or larger, install a new Rotor
Bearing Seal.
Take all measurements 90 degrees to the left of the
dowel hole when facing the hub side of the Seal.
7. Align the Rear End Plate (40), cavity and pin up, with
the larger hole in the Rotor Bearing Seal.
8. Press the Rear Rotor Bearing onto the Controller As-
sembly (42). Press the Controller Assembly into the
Bearing Cage (45) to within 1/8" of seating.
