Lubrication
Each time a Series 2705P1 Impact Wrench is disassembled for
maintenance and repair or replacement of parts, lubricate the tool
as follows:
Work approximately 4 to 6 cc of Ingersoll Rand No. 100 Grease
1.
into the impact mechanism. Coat the Anvil (43) lightly with grease
around the Hammer Case Bushing (40). Inject approximately 1 to
2 cc of grease into the Grease Fitting (2).
Disassembly
General Instructions
1.
Do not disassemble the tool any further than necessary to replace
or repair damaged parts.
2.
When grasping a tool or part in a vise, always use leather-covered
or copper-covered vise jaws to protect the surface of the part
or tool 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 repairs or
replacement.
4.
Do not disassemble the tool unless you have a complete set of
new gaskets and O-rings for replacement.
Disassembly of the Impact Wrench
1.
Clamp the handle of the Impact Wrench in a vise with the square
driver upward.
2.
Unscrew and remove the three Hammer Case Cap Screws (41).
3.
While lightly tapping on the end of the Anvil (43) with a plastic
hammer, lift off the Hammer Case (38).
4.
Grasp the Hammer Frame (34) and carefully lift off the entire
impact mechanism, making certain not to drop the two
Hammer Pins (35). If it is necessary to disassemble the impact
mechanism, refer to Disassembly of the Impact Mechanism.
If it is unnecessary to disassemble the impact mechanism, set it
aside intact.
Disassembly of the Impact Mechanism
1.
Set the mechanism, driver end up, on the workbench.
Note the twin Hammers (37) within the Hammer Frame. These
are identical but must be placed in the Hammer Frame in a
certain 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 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 Hammers 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
hammers, gently lift the Anvil, simultaneously rotating it
clockwise about 1/8 of a turn, from the Hammer Frame.

2. While slowly rotating the Reverse Valve (12), withdraw it from the
Reverse Valve Bushing (3).
Be careful you do not lose the Reverse Valve Detent Ball (13) and
Spring (14) from the hole in the side of the Reverse Valve.
Disassembly of the Motor
1.
