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 fit in or on a
subassembly unless the removal of that part is necessary
for repair or replacement.
4. Do not disassemble the Impact Wrench unless you have a
complete set of new gaskets and O-Rings for replacement.

Bushing (36). Inject approximately 2 to 4 cc of grease into
the Grease Fitting (15).
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.
3. Remove the Hammer Case Gasket (34) 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 (30) from the rear of the Hammer Frame and set
it aside on a clean bench.
5. Place the impact mechanism on a bench with the Anvil
(pointing upward). Make sure that the Hammer Pins (33)
do not drop out of the Hammer.
6. Lift the Hammer Case off of the Anvil (38). If it is
unnecessary to disassemble the impact mechanism, set
it aside intact.
Disassembly of the Impact Mechanism
Disassemble the impact mechanism as follows:
1. Set the mechanism, driver end up, on the workbench.
Using a felt tipped pen, mark one end of the Hammer " "
with the arrow pointing upward.
2. With the mechanism sitting upright on the workbench,
slowly rotate the Anvil in a clockwise direction until it
comes up solid.
If you continue to rotate the Anvil, it will cam the
Hammer out of engagement. Don't do this; merely rotate
the Anvil until it comes up solid.
3. Hold the Hammer Frame firmly and, without disturbing the
Hammer, gently lift the Anvil from the Hammer Frame.
4. With the Anvil removed, lift out the two Hammer Pins.
The Hammer is now free to slide from the Hammer
Frame. Be careful not to drop it.
Disassembly of the Reverse Valve
1. Remove the four Backcap Bolts (12).
2. Lift the Backcap off of the rear of the Housing.
3. Discard the Backcap Gasket (13) and replace it with a
new one when assembling the tool.
4. Use a hooked tool to remove the Reverse Valve (29) from
the reverse valve bushing. Set the Reverse Valve aside
on a clean bench.
5. Remove and discard the Reverse Valve O-Ring (28).
Replace it with a new one when assembling the Reverse
Valve.
6. Use a flat, thin blade screwdriver to remove the Reverse
Lever Retaining Ring (17) and Reverse Lever Spring (18)
from the Reverse Lever (16).
7. Remove the Reverse Lever from the Backcap.
