4. Place the Exhaust Deector Seal (6) on the smaller shoulder of
the Motor Housing. To hold the Seal in position, lightly coat the
Seal and shoulder with Ingersoll Rand No. 28 Grease. Place the
Exhaust Deector on the rear of the Housing, aligning the notch
in the Deector with the alignment pin in the Housing. Secure
the Deector to the Housing with the Inlet Bushing Assembly.
Use a torque wrench and tighten the Inlet Bushing Assembly to
15 to 18 ft-lb (20 to 24 Nm) torque.
5.
Before installing throttle components, make sure that the Motor
Housing is positioned correctly. The Throttle Lever should be facing
downward. Shift leftward the Throttle Valve Plunger (12), Throttle
Valve Ball (14) and Throttle Valve Spring (11) into the Motor Housing.
Position the Throttle Valve Cap (13) on the Throttle Valve Spring.
Screw the Valve Cap into the Motor Housing until the cap is within
approximately two threads of being ush with the Housing. Apply
a light, uniform coat of thread locking compound to the remaining
two threads. Tighten the Valve Cap securely and place the Housing
on a workbench with the Valve Cap facing downward. Allow the
thread locking compound to cure approximately ve minutes.
Assembly of the Motor
1.
Place the Rear End Plate (28) on the short, unsplined shaft of the
Rotor (33) with the counterbore away from the body of the Rotor.
2. Using a sleeve that contacts the inner ring of the Rear Rotor
Bearing (27), press the Bearing onto the shaft until the Rear End
Plate just contacts the rotor body.
3. The clearance between the Rear End Plate and Rotor is critical. While
pressing down with your nger on the outer edge of the End Plate
on the Bearing side, insert a .002” (.05 mm) feeler gauge between
the face of the Rotor and End Plate directly opposite the point
where pressure is applied.
This measurement must be made at the outside diameter of the
rotor body.
Supporting the End Plate, lightly tap the shaft with a plastic
hammer to increase the space. Press the Bearing farther onto
the shaft if the space is too wide. When the proper clearance is
obtained, install the Rear Rotor Bearing Retainer (26) on the shaft.

4. Place the Rotor, with the splined end up, in a block which has
clearance for the Rotor Bearing and supports the Rear End Plate.
5. Wipe each Vane (34) with a light lm of Ingersoll Rand No. 10 oil
and place a Vane in each slot in the Rotor.
6. Note that the Cylinder (32) has a notch in one end. Place the
Cylinder, notched end up, down over the Rotor and against the
Rear End Plate, aligning the dowel hole in the Cylinder with the
U-shaped notch in the rim of the Rear End Plate.
7. Install the Front Rotor Bearing (27) in the Front End Plate (30) and
retain it with the Front Rotor Bearing Retainer (31).
8. Using a sleeve that contacts the inner ring of the bearing, press
the assembled Front End Plate, at side rst, on the splined end
of the Rotor until the End Plate just contacts the Cylinder.
9.
Install the Rear End Plate Gasket (29) in the Motor Housing, aligning
the small notch in the Gasket with the dowel pin hole in the Housing.
10. Insert a thin, rigid wire into the dowel pin hole at the bottom of
the motor recess in the Motor Housing. Grasping the assembled
motor by the spline on the Rotor and with the dowel pin holes of
the Front End Plate and Cylinder aligned with the U-shaped notch
in the Rear End Plate, install the assembled motor in the Motor
Housing. Maintain alignment between the motor and Motor
Housing by passing the aligned dowel holes in the assembled
motor over the wire positioned in the Motor Housing. Withdraw
the wire and install the Cylinder Dowel (35), making certain the
Cylinder Dowel is ush with or below the Front End Plate.
Assembly of the Gearing
For Models 1AL1, 1P06, 1P09, 1P13, 1P21, 1P38, 1P44, 1P76,
1S30, 1S39 and 1S60
1. Set the Gear Case (38) on the table of an arbor press with the
threaded end down.
2. Using a sleeve that will contact the outer ring of the bearing,
press the Rear Spindle Bearing (46), open side rst, into the
bearing recess until it seats.
3. Work some grease into the teeth of the Spindle Planet Gears (40)
and onto the planet gear shafts on the Spindle (39).
4. Slide the Spindle into the Gear Case so that the spindle shaft
passes through the bore of the Rear Spindle Bearing.
5. For Angle Drills, install the Spindle Retaining Ring (49A) into
groove on the Spindle shaft. 6. For Pistol and In-line Drills, install
the Spindle Bearing Spacer (47) and Front Spindle Bearing (48),
shielded side out, on the shaft of the Spindle.
7. Install the Spindle Bearing Retainer (19) in the groove in the Gear
Case.
8. Slide the Spindle Planet Gears onto the planet gear shafts,
making certain the teeth on the Gears mesh with the teeth of the
