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 Cylinder. With that end trailing,
install the Cylinder Assembly over the Rotor and Vanes against
the Front End Plate. Make certain the Cylinder Front Alignment
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 Assembly
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 Bearing (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 leathercovered
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.
3.
If the tool is equipped with a Memory Chip (9), install it (with the
leads entering first) in the pocket at the bottom of the Back Cap.
4.
Make certain the tab on the inside edge of the Back Cap Gasket
(7) is aligned with the pocket for the Memory Chip and install the
Gasket, metal face leading, in the recess of the Back Cap against
the face with the cavity containing the Muffler Elements.
4
5.
Position the gasket end of the alignment dowel against the inlet
hub on the Motor Housing. Align the flats on the Cap with the
flats on the Housing. Orient the Back Cap and slide the Back Cap
Assembly off the alignment dowel and onto the Motor Housing.
6.
The Exhaust Diffuser (15) has one slot that is longer than the
other five slots. The Back Cap has a short, molded stud projecting
from inlet end. Place the Exhaust Diffuser against the Back Cap
with the long slot encircling the molded stud. Rotate the Diffuser
counterclockwise until the wall of the slot stops against the stud.
The exhaust ports are now in the full open position which will
provide maximum free speed.
7.
Being careful not to damage it, insert the Throttle Valve Seat (12)
into the central opening at the inlet end of the Motor Housing
at an angle until it clears the threads in the Housing. Using a rod
with a flat end and no sharp edges, push the Seat to the bottom
of the opening until it seats flush.
8.
Using needle nose pliers, insert the Throttle Valve (13), long stem
leading, into the opening against the Seat. Center the Valve in
the Seat.
9.
Install the Throttle Valve Spring (14) in the opening so that it
encircles the Valve.
10.
If the Inlet Screen (18) required replacement, use a wooden dowel
to carefully push a new one into the Inlet Bushing (16).
11.
If the Inlet Bushing Seal (17) is nicked or damaged, carefully install
a new one over the threads of the Inlet Bushing.
12.
Thread the Inlet Bushing Assembly through the Diffuser and Back
Cap into the Motor Housing. Using a 1-3/16" wrench on the flats
of the Back Cap to keep it from turning, tighten the Inlet Bushing
between 15 and 20 ftlbs. (20 and 27 Nm) torque.
13.
The Throttle Plunger (5) has a lengthwise flat on the outer edge
at one end of the Plunger. Insert the Plunger, flat end first, into
the cross hole in the Housing. Push on the end of the Plunger to
make certain it springs back from contact with the stem of the
Throttle Valve.
14.
Position the Throttle Lever (10) in the slot in the Back Cap and
Motor Housing and using a 1/16" diameter rod, align the holes
through the Back Cap, Motor Housing and Throttle Lever. While
maintaining alignment, install the Throttle Lever Pin (11) in place
of the rod by tapping it through all three pieces.
15.
Remove the assembled Housing from the vise jaws.
16.
Lightly grasp the flats at the inlet end of the Motor Housing in
leather-covered or copper-covered vise jaws with the motor bore
upward.
17.
Grasp the spline of the Rotor (26) in the assembled motor and
after aligning the End Plate Alignment Pin (29) with the internal
notch in the motor end of the housing bore, insert the assembled
motor into the Motor Housing. Make certain the motor is far
enough into the Housing to have the undercut below the internal
housing thread visible.
18.
Lubricate the Motor Seal (31) with O-ring lubricant and install
it around the Front End Plate (28) and into the undercut in the
Housing.
19.
Align the tab of the Motor Clamp Washer (32) with the internal
notch in the Housing and install it over the rotor hub and End
Plate Alignment Pin against the Motor Seal. Make certain the Pin
enters the hole in the Washer and the Washer is flat against the
Seal.
Apply some Ingersoll Rand No. 67 Grease to the spline on the
20.
rotor shaft.
21.
Thread the assembled Gear Case (41) and Spindle Assembly (40),
gear case end leading, into the Motor Housing and tighten the
joint between 15 and 20 ft- lbs. (20 and 27 Nm) torque.
22.
Install the Housing Grip (43), internal slotted end leading, over the
Gear Case and Housing and engage the slots in the Grip with the
projections on the Housing.
23.
Install the Grip Retainer (42) in the groove on the Gear Case to
secure the Grip.
24.
Remove the tool from the vise jaws and thread the Chuck (50)
onto the Spindle.
25.
Check the free speed of the tool using a tachometer and
following the instructions in the SPEED ADJUSTMENT section
of this manual.
