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 (23) 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. Using a small screwdriver, work the Spindle Bearing Seat
(45) into the internal groove nearest the notched end of
the Gear Case (42).
2. Stand the Gear Case, notched end upward, on the table
of an arbor press. Using a piece of tubing that contacts
the outer race of the Spindle Bearing (43), press a new
Bearing into the Gear Case against the Seat.
3. Lubricate the gears in the Spindle Assembly (41) with
Ingersoll Rand No. 67 Grease.
4. Invert the Gear Case and using another piece of tubing
that supports the inner race of the Bearing and clears the
output end of the Spindle Assembly, press the Spindle
Assembly into the Bearing from the motor end of the
Gear Case.
5. Using snap ring pliers, install the Spindle Bearing
Retainer (44) in the external groove near the drive end of
the spindle.
6. For all tools except Series QA35, apply some
Ingersoll Rand No. 67 Grease to the Planet Gear Head
Spacer (40) and the shafts of the Planet Gear Head
Assembly (37).
7. For all tools except Series QA35, insert the Planet
Gear Head Spacer (40) and Planet Gear Head Assembly
(37), spline hub leading, into the open end of the Gear
Case.
8. For Series QA05, QA08, QA12 and QA17, apply
Ingersoll Rand No. 67 Grease to the three Planet Gears
(38) and install them on the shafts of the Planet Gear
Head Assembly.
9. For Series QA35, apply Ingersoll Rand No. 67 Grease
to the Gear Head Pinion (39) and while meshing the gear
teeth, insert it in the opening between the three Planet
Gears.
10. For Series QA21, QA27 and QA35, install the Planet
Gear Head Drive Plate (36) on the shafts of the Planet
Gear Head Assembly.
11. Place the Gear Head Spacer (35) in the Gear Case and
secure the assembly by using snap ring pliers to install
the Gear Retainer (34) in the angular groove inside the
Gear Case.
Assembly of the TRL5F28 and TRL5F40 Angle
Heads
1. If the Spindle Upper Bearing (58) was removed, stand the
output end of the Lower Angle Head (56) on the table of
an arbor press. Using a Needle Bearing Inserting Tool as
shown in Dwg. TPD786, press the Bearing into the small
opening at the top of the Angle Head. Press Plug (57)
until top is flush with Upper Angle Head (56) surface.
2. Apply a light film of Ingersoll Rand No. 67 Grease to the
shaft of the Bevel Pinion (55) and to the inside of the
Pinion Front Bearing (54).
3. Slide the Pinion Front Bearing, stamped end trailing, onto
the shaft until it stops against the back of the gear.
4. Without distorting the Angle Head, support the hex flats
of the Angle Head in a machine vise on the table of an
arbor press with the notched end upward and the Head
resting on a solid stop. Apply 2 to 4 cc of Ingersoll Rand
No. 67 Grease to the gear on the end of the Bevel Pinion.

5. Insert the gear end of the Bevel Pinion into the notched
end of the Angle Head while aligning the Pinion Front
Bearing with the central opening.
6. Use a piece of tubing that clears the shaft of the Bevel
Pinion and the inner wall of the Angle Head and is
between 1.455" and 1.465" (36.95 and 37.21 mm) long to
press the Bearing into the Angle Head. Press the Bearing
until the trailing end of the pressing tube is flush with the
notched end of the Angle Head.
7. Apply some Ingersoll Rand No. 67 Grease to the Pinion
Rear Bearing (53) and slide it onto the shaft of the Bevel
Pinion and into the Angle Head recess.
8. Use the 9/16" hex stock with clearance for the bevel
pinion shaft that was used during disassembly to screw
the Angle Head Plug (52) into the Angle Head against
Pinion Rear Bearing. Tighten the Plug between 10 and 15
ft. lbs. (13.5 and 20.3 Nm) torque.
9. Remove the assembly from the machine vise and
position it in leather-covered or copper-covered vise jaws
with the opening for the output spindle upward.
10. If the spindle Upper Bearing Shaft (59) was removed,
stand the output end of the Spindle (60) on the table of an
arbor press. One end of the Shaft has a bevel and the
other end is rounded. Press the Shaft, bevel leading, into
the gear end of the Spindle until rounded end extends
above the shoulder of the gear 0.551" to 0.554"
(14.0 to 14.1 mm).
11. Slide the Spindle Bearings (61) onto the shaft of the
Spindle against the gear and insert the assembled
Spindle, gear end leading, into the Angle Head. Push the
Bearing into the housing below the threads.
NOTICE
The thread in the following step is a left-hand thread.
Rotate the Coupling Nut (62) in the indicated direction to
tighten it.
12. Slide Lower Housing Coupling Nut (62) onto Coupler (63)
so Coupling Nut rests on flange. Grip on flats of Coupler
and thread into Upper Angle Head housing (56). Tighten
the Coupler between 5 and 10 ft-lbs (6.8 and 13.5 Nm).
13. If the Spindle Upper Bearing (58) was removed, stand the
output end of the Lower Angle Head (66) on the table of
an arbor press. Using a Needle Bearing Inserting Tool as
shown in Dwg. TPD786, press the Bearing into the small
opening at the top of the Angle Head. Press Plug (57)
until top is flush with Lower Angle Head (66) surface.
14. If the Spindle Upper Bearing Shaft (59) was removed,
stand the output end of the Spindle (67) on the table of an
arbor press. One end of the Shaft has a bevel and the
