Assembly
General Instructions
Always press on the inner ring of a ball-type bearing when
1.
installing the bearing on a shaft.
Always press on the outer ring of a ball-type bearing when
2.
pressing the bearing into a bearing recess.
3.
Whenever grasping a tool or part in a vise, always use leather-
covered or copper-covered vise jaws. Take extra care with
threaded parts or housings.
4.
Always clean every part and wipe every part with a thin film of oil
before installation.
5.
Apply a film of O-ring lubricant to all O-rings before final
assembly.
Assembly of the Throttle Mechanism
1.
Place the Trigger (10) in the Housing (1) and secure it with the
Trigger Pin (11).
2.
Install the Throttle Valve Face (6) on the Throttle Valve (5).
3.
Install the Throttle Valve stem (8), Throttle Valve and Throttle Valve
Spring (7).
4.
Install the Air Strainer Assembly (9) and tighten it to 30 to 35 ft-lb
(40.5 to 47.5 Nm) torque.
Assembly of the Motor
1.
Using a sleeve that will contact only the outer ring of the bearing,
press the Front Rotor Bearing (24) into the Front End Plate (30)
and the Rear Rotor Bearing (23) into the Rear End Plate (31).
2.
Slip the Front End Plate and Bearing over the splined hub of the
Rotor (22).
3.
Grasp the splined hub of the Rotor in leather-covered or copper-
covered vise jaws so that the Rotor is in a vertical position.
4.
Dampen each Vane (29) with light oil and insert a Vane into each
vane slot.
5.
Set the Cylinder (26) over the Rotor and onto the Front End Plate.
6.
Slide the Rear End Plate and Bearing onto the rotor hub and
against the Cylinder.
7.
Install the Rear Rotor Bearing Retainer (25) in the groove on the
rotor hub.
8.
Align the dowel hole in both End Plates with the one through
the Cylinder, and insert a guide rod 5/32" diameter x 6" long (3.9
mm diameter x 152 mm long). Allow the rod to protrude from the
Rear End Plate.
9.
Grasp the handle of the Motor Housing in leather-covered or
copper-covered vise jaws so that the bore of the Motor Housing
is horizontal.
10.
Wipe a thin film of light grease on the End Plate Gasket (32) and
press the Gasket firmly against the Rear End Plate.
11.
Insert the protruding end of the guide rod into the dowel hole in
the bore of the Motor Housing, and slide the motor along the rod
until it is completely seated.
12.
Remove the guide rod and replace it with the Cylinder Dowel (27).
13.
Reposition the Motor Housing in the vise so that the open face of
the Motor Housing is upward.
Place the two Motor Clamp Washers (33), convex side first,
14.
against the Front End Plate so that the inner rim of the leading
Washer contacts the End Plate and the outer rim of the trailing
Washer contacts the Hammer Case Pilot (38A).
15.
Place the Rear Hammer Frame Washer (36) over the hub of the
Rotor and against the Front Rotor Bearing.
Assembly of the Reverse Valve
1.
Make certain the Reverse Valve Bushing Seals (4) are properly
located in the undercuts in the Reverse Valve Bushing (3).
2.
Dampen the Reverse Valve (12) with light oil. Install the Reverse
Valve Detent Spring (14) followed by the Reverse Valve Detent Ball
(13) in the hole in the Reverse Valve. With the Impact Wrench in
an upright horizontal position, and while facing the handle end of
the Impact Wrench, slowly rotate the Reverse Valve and insert it
from left to right in the splined end of the Reverse Valve Bushing.

3.
Apply a thread locking compound to the Reverse Valve Knob
Screw (16). Attach the Reverse Valve Knob (15) to the Reverse
Valve with the Reverse Valve Knob Screw, and tighten the Screw
to 40 to 50 in-lb (4.5 to 5.6 Nm) torque.
Assembly of the Impact Mechanism

HALF- - ROUND NOTCH ON LEFT
(Dwg. TPD652)
1.
Coat the Hammers (37) with a light film of Ingersoll Rand Impact
Wrench Grease No. 100.
2.
Replace the Hammers in the Hammer Frame (34) exactly as they
were when you marked them prior to disassembly.
If you are installing new Hammers, or want to change the
location of the existing Hammers to utilize both impacting
surfaces, slide the Hammers in the Hammer Frame so that the
half-round notch on one Hammer is located on one side of the
Frame and the half-round notch on the other Hammer is located
on the other side of the Frame.
3. Replace the Hammer Pins (35).
4. Examine the base of the Anvil (43) and note its contour. While
looking down through the Hammer Frame, swing the top
Hammer to its full extreme one way or another until you can
match the contour of the Anvil. Enter the Anvil into the Hammer
Frame and through the first Hammer. Swing the bottom Hammer
in the opposite direction from the top Hammer and maneuver
the Anvil slightly until it drops into the bottom Hammer.
Assembly of the Impact Wrench
1.
Set the assembled impact mechanism down over the splined hub
of the Rotor.
2.
Smear a thin film of Ingersoll Rand Impact Wrench Grease No.
100 on the inside surface of the Hammer Case Bushing (40), and
place the Hammer Case down over the Anvil and against the
Motor Housing.
3.
Install the Hammer Case Cap Screws (41). Tighten the Hammer
Case Cap Screws to 60 to 70 in-lb (6.8 to 7.9 Nm) torque.
