MAINTENANCE SECTION
4. Invert the Front 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 Intermediate Spindle Assembly into the Bearing
from the clutch end of the Front Gear Case.
5. Using snap ring pliers, install the Spindle Bearing
Retaining Ring (93) in the external groove near the
angle head end of the spindle.
Assembly of the Angle Head
1. If the Spindle Upper Bearing (102) was removed,
stand the output end of the Angle Head (100) on the
table of an arbor press. Pressing against the closed
end of a new Bearing, press the Bearing into the
small opening until the trailing end is flush with the
outside surface of the Angle Head.
2. Apply a light film of Ingersoll–Rand No. 67 Grease
to the shaft of the Bevel Pinion (107) and to the
inside of the Pinion Front Bearing (108).
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
press the Bearing into the Angle Head against the
stop.
7. Apply some Ingersoll–Rand No. 67 Grease to the
Pinion Rear Bearing (109) 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 (106) into the Angle
Head against Pinion Rear Bearing. Tighten the Plug
between 8 and 12 ft–lbs. (10.8 and 16.2 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. Stand the Spindle (113) on the table of an arbor press
and using a piece of tubing that clears the shaft of the
Spindle and contacts the inner ring of the Spindle
Lower Bearing (112), press the Bearing onto the shaft
of the Spindle until it stops against the shoulder.
11. In the same manner, press the Bevel Gear (110), flat
end leading, onto the hex portion of the spindle shaft.
Likewise, press the Bevel Gear Retainer (111) onto
the spindle shaft until it stops against the gear face.
12. Insert the assembled Spindle, output end trailing, into
the Angle Head.
The thread in the following step is a left–hand
thread. Rotate the wrench counterclockwise to
tighten the Cap.
13. Thread the Lower Spindle Bearing Cap (116) into the
Angle Head and using the Spindle Bearing Cap
Wrench (Part No. 141A12–26), tighten the Cap be-
tween 8 and 12 ft–lbs. (10.8 and 16.2 Nm) torque.
14. For TRL2S6 Angle Heads, install the Spindle Det-
ent (114) into position through the end of the Spindle
and push the Detent Retainer (115), tapered end lead-
ing, into the end of the Spindle.
For TRL2Q4 Angle Heads, place the Spindle Detent
(114) into the hole in the groove of the Spindle.
Spread the Detent Retainer (115) and install it on the
Spindle to capture the Detent.
For TRL2H4 Angle Heads, install the Spindle
Detent (114) in the internal groove in the Spindle
15. Remove the assembly from the vise jaws and slide
the Coupling Nut (104), threaded end trailing, onto
the notched end of the Angle Head. Move the Nut far
enough onto the housing to install the Coupling Nut
Retainer (105) in the annular groove at the notched
end of the Angle Head.
Assembly of the Tool
1. Lightly grasp the flats at the inlet end of the Motor
Housing (1) in leather–covered or copper–covered
vise jaws with the motor bore upward.
2. Grasp the spline of the Rotor (28) in the assembled
motor and after aligning the End Plate Alignment Pin
(31) 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.
3. Lubricate the Motor Seal (33) with o–ring lubricant
and install it around the Front End Plate (30) and into
the undercut in the Housing.
4. Align the tab of the Motor Clamp Washer (34) 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.
5. Apply some Ingersoll–Rand No. 67 Grease to the
spline on the rotor shaft.
6. Thread the assembled Rear Gear Case (43), output
spindle trailing, into the Motor Housing and using a
1–1/16” wrench, tighten the joint between 15 and 20
ft–lbs. (20 and 27 Nm) torque.
