4. Wipe each Vane (27) with a light film of Ingersoll--
Rand No. 10 Oil and place a Vane in each slot in the
Rotor.
5. One end of the Cylinder Assembly (23) has a notch
that breaks the outer wall and end face of the Cylin-
der. With that end trailing, install the Cylinder As-
sembly over the Rotor and Vanes against the Front
End Plate. Make certain the Cylinder Front Align-
ment Pin (25) enters the hole in the Front End Plate.
6. Install the Rear End Plate Assembly (20), flat face
leading, on the rear hub of the Rotor. Make certain
the Cylinder Rear Alignment Pin (24) enters the hole
in the Rear End Plate.
7. Examine the Rear End Plate Face Plate (21) for
scratches. If it is scratched, replace it. If it is not,
slide it onto the rear hub of the Rotor and onto the
Cylinder Rear Alignment Pin against the Rear End
Plate. Some pressure may be required to fit the hole
in the Plate onto the Alignment Pin.
8. Using snap ring pliers, install the Rear End Plate As-
sembly Retainer (22) in the annular groove on the
rear rotor hub to secure the assembly in position.
9. Set the assembled motor aside.
Assembly of the Gearing
1. Work some Ingersoll--Rand No. 67 Grease into the
gearing of the Spindle Assembly (40).
2. Insert the threaded end of the Spindle Assembly into
the threaded end of the Gear Case (41) while meshing
the teeth of the gears with the spline inside the Gear
Case.
3. Support the gear end of the Spindle Assembly on the
table of an arbor press while leaving clearance for the
Gear Case. Using a piece of tubing that will clear the
shaft and contact the inner ring of the Spindle Bear-
ing (46), press the Bearing onto the shaft of the
Spindle Assembly until it contacts the gear hub.
4. Using snap ring pliers, install one of the Bearing
Stops (48) in the internal groove nearest the Bearing.
5. Apply some Ingersoll--Rand No. 67 Grease to the
Bearing Spacer (47) and slide it onto the shaft of the
Spindle Assembly with the smaller end trailing.
6. Using snap ring pliers, install the second Bearing
Stop in the internal gear case groove nearest the
threaded spindle end.
7. Stand the assembled Gear Case on the table of an
arbor press with the output Spindle upward. Install
the Spindle Cap Bearing (49) over the output shaft,
and using a piece of tubing that contacts the outer
ring of the Bearing, press the Bearing into the Gear
Case against the Bearing Stop.
8. Insert the Planet Gear Head Spacer (39) and Planet
Gear Head Assembly (36), spline hub leading into the
open end of the Gear Case.
9.
For Series QS05, QS09, QS15 and QS20,
apply
Ingersoll--Rand No. 67 Grease to the three Planet
Gears (37) and install them on the shafts of the Planet
Gear Head Assembly.
10.
For Series QS15 and QS20,
apply Ingersoll--Rand
No. 67 Grease to the Gear Head Pinion (38) and
while meshing the gear teeth, insert it in the opening
between the three Planet Gears.
11.
For Series QS30, QS38 and QS51,
install the Planet
Gear Head Drive Plate (35) on the shafts of the Planet
Gear Head Assembly.
12. Place the Gear Head Spacer (34) in the Gear Case
and secure the assembly by using snap ring pliers to
install the Gear Retainer (33) in the annular groove
inside the Gear Case.
Assembly of the Tool
1. Lightly grasp the flats on the Motor Housing (1) in
leather--covered or copper--covered vise jaws with the
inlet end of the tool upward.
2. Insert a 5/8” dowel through the opening in the Back
Cap (6), and using the dowel as an alignment device,
install the three Muffler Elements (8) in the cavity of
the Back Cap. Make certain the notches in the outer
edge of the Elements fit over the memory chip pocket
in the bottom of the Cap.
