WARNING
Always wear eye protection when operating or performing maintenance on this tool.
●Always turn o the air supply and disconnect the air supply hose before installing, removing or adjusting any accessory on this tool,
or before performing any maintenance on this tool.
Note: When reading the instructions, refer to exploded diagrams in Parts Information Manuals when applicable (see under Related Documentation
for form numbers).
Lubrication
Each time a Series 2922P1 and 2922P3 Impactool is disassembled for maintenance and repair or replacement of parts, lubricate the tool as
follows:
1. Work approximately 12 to 15 cc of Ingersoll Rand No. 170 Grease into the impact mechanism. Coat the Anvil (40) lightly with grease around
the Hammer Case Bushing (38). Inject approximately 2 to 4 cc of grease into the Grease Fitting (17).
2. Use Ingersoll Rand No. 10 Oil for lubricating the motor. Inject approximately 1 to 2 cc of oil into the air inlet before attaching the air hose.
Disassembly
General Instructions
1. Do not disassemble the tool any further than necessary to replace or repair damaged parts.
2. Whenever grasping a tool or a part in a vise, always use leather-covered or copper-covered vise jaws to protect the surface of the part and
help prevent distortion. This is particularly true of threaded members and housings.
3. Do not remove any part which is a press t in or on a subassembly unless the removal of that part is necessary for repair or replacement.
4. Do not disassemble the Impactool unless you have a complete set of new gaskets and O-rings for replacement.
5. Whenever grasping a tool or a part in a vise, always use leather-covered or copper-covered vise jaws to protect the surface of the part and
help prevent distortion. This is particularly true of threaded members and housings.
Disassembly of the Hammer Case and Anvil Assembly
NOTICE
●Before disassembling this tool, clamp the anvil drive in leather-covered or copper-covered vise jaws with the Backcap (16) pointing
upward. See Drawing TPD1918.
(Dwg. TPD1918)
1. Unscrew and remove the four Backcap Bolts (14).
2. Lift the assembled Motor Housing (1) o of the Hammer Case (39). Make sure that you hold the Backcap in position on the Housing and that
the motor does not come out of the Housing.
3. Remove the Hammer Case Gasket (37) and replace with a new one when assembling the Hammer Case to the Housing.
4. Remove the Hammer Case and impact mechanism assembly from the vise. Remove the Hammer Frame Washer (33) from the rear of the

Disassembly of the Impact Mechanism
1. Set mechanism, driver end up, on a workbench.
NOTICE
●Note the twin hammers within the Hammer Frame. These are identical, but must be placed in the Hammer Frame in a particular
relationship. Using a felt-tipped pen, mark the top Hammer “T↑”and the bottom Hammer “B↑” with the arrows pointing upward.
Mark both Hammers on the same end.
2. With the mechanism sitting upright on a workbench, slowly rotate Anvil in a clockwise direction until it comes up solid.
NOTICE
●If you continue to rotate the Anvil, it will cam the Hammers out of engagement. Do not do this; merely rotate the Anvil until it comes
up solid.
3. Hold Hammer Frame rmly and, without disturbing Hammers, gently lift Anvil, simultaneously rotating it clockwise about 1/8 of a turn, from
the Hammer Frame.
4. With Anvil removed, lift out the two Hammer Pins.
NOTICE
●The twin hammers are now free to slide from the Hammer Frame. Be careful not to drop them.

2. Lift the Backcap o of the rear of the Housing.
3. Discard the Backcap Gasket (15) and replace it with a new one when assembling the tool.
4. Use a hooked tool to remove the Reverse Valve (32) from the reverse Valve bushing. Set the Reverse Valve aside on a clean bench.
5. Remove and discard the Reverse Valve O-ring (31). Replace it with a new one when assembling Reverse Valve.
6. Use a at, thin blade Screwdriver to remove the Reverse Lever Retaining Ring (19) and Reverse Lever Spring (20) from the Reverse Lever (18).
7. Remove the Reverse Lever from the Backcap.
Disassembly of the Motor
1. Remove the four Backcap Bolts.

4. Insert the Vanes (26) in the vane slots on the Rotor.
5. Install the Front and Rear Cylinder Dowels (28) in the Cylinder (27).
6. Slide the Cylinder over the Rotor and Vanes making sure that the Rear Cylinder Dowel enters the notch in the outside diameter of the Rear
End Plate.
(Dwg. TPD1921)
NOTICE
●If more power is needed for forward operation than for reverse operation, install the Cylinder with exhaust ports to the RIGHT of top
dead center (1 o’clock position).
7. Install the assembled Front End Plate and Bearing over the front, splined end of the Rotor making sure that the front Cylinder Dowel ts into
the notch in the outside diameter of the Front End Plate.
8. Grasp the Housing with one hand and set it upside down on its top. With the other hand, carefully guide the Motor Assembly into the
Housing, making sure that the side of the motor assembly containing the Cylinder Dowels is oriented to the top of the Housing. Install

1. Coat the Hammers (35) with a light lm of Ingersoll Rand No. 170 Grease.
2. Replace the Hammers in the Hammer Frame (34) exactly as they were when you marked them prior to disassembly.
NOTICE
●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. These Hammers must be installed with the wide bevels
facing the web of the Hammer Frame as illustrated.
3. Replace the Hammer Pins (36).
4. Examine the base of the Anvil (40) 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 rst
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 Anvil
1. Place the Hammer Frame Washer (33), hub side rst, over the hub of the Rotor and against the Front Rotor Bearing.
2. Set the assembled impact mechanism down over the splined hub of the Rotor. If the impact mechanism was disassembled, refer to Assembly
of Impact Mechanism.
3. Position the new Hammer Case Gasket (37) on Housing.
4. Work approximately 12 to 15 cc of Ingersoll Rand No. 170 Grease into the impact mechanism.
5. Smear a thin lm of Ingersoll Rand No. 170 Grease on the inside surface of the Hammer Case Bushing (38) and place the Hammer Case (39)
down over the Anvil and against the Motor Retainer.
6. Install the Backcap Bolts and tighten them to 10 to 12 ft-lb (13 to 16 Nm) torque.
7. Remove the Impactool from the vise and inject 2 to 4 cc of Ingersoll Rand No. 170 Grease into the Grease Fitting (17).

Assembly of the Tool
1. Wipe a thin lm of the recommended grease on the inside of the Hammer Case Bushing (38) and insert the assembled impact mechanism
into Hammer Case (39).
2. Secure the Hammer Case and impact mechanism by the anvil in leather-covered or copper-covered vise jaws. See Dwg. TPD1918.
(Dwg. TPD1918)
3. Install a new Hammer Case Gasket (37) on the Hammer Case making sure that the holes in the gasket align with the holes in the Hammer
Case.
NOTICE
●When installing optional Hanger Kit, place Gasket on the Hammer Case followed by the Hanger.
4. Wipe a small amount of the recommended grease on the at side of the Hammer Frame Washer (33) and place it on the splined face of the
Hammer Frame (34) with the hub end of the washer pointing up.
NOTICE
●When installing optional Hanger Kit, place additional washer provided between the Hammer Frame and Hammer Frame Washer.
5. Set the fully assembled Motor Housing over the opening in the Hammer Case. Insert the spline drive of the Rotor into the splined hole of the
impact mechanism. Make sure of the wide section of the Hammer Case is just above the Trigger.
6. Place a new Backcap Gasket (15) over the rear of the Housing making sure that the holes in the Gasket align with the holes in the Housing
and that the prole of the Gaskets matches the prole of Housing.
7. Place a Motor Clamp Washer (21) over the rear of the motor with the convex side up and matching the large outside diameter of the Rear
End Plate.
8. Place the Backcap (16) over the back of the Housing making sure that the Reverse Valve Lever (18) is in the full-forward (clockwise) position
with the lugs in the Lever engaging the slots in the Reverse Valve. Make sure that the index mark on the Reverse Valve lines up with the index
mark on the reverse valve bushing.
9. Install the four Backcap Bolts and tighten to 10-12 ft-lb (13-16 Nm) torque.
