3.Do not remove any part which is a press fit in or on a subassembly unless the removal

4.Do not disassemble the tool unless you have a complete set of new gaskets and O-rings replacement.

Disassembly of the Impact Wrench

1.Clamp handle of Impact Wrench in a vise with square driver upward.

2.Unscrew and remove the three Hammer Case Cap Screws (38).

3.While lightly tapping on end of Anvil (40) with a plastic hammer, lift off Hammer Case (35), Hammer Case Pilot (35B) and Hammer Case Gasket (35A).

4.Grasp Hammer Frame (30) and carefully lift off entire impact mechanism, making certain not to drop two Hammer Pins (31). If it is necessary to disassemble the impact mechanism, refer to Disassembly of the Impact Mechanism. If it is unnecessary to disassemble impact mechanism. set it aside intact.

Disassembly of the Impact Mechanism

1.Set mechanism, driver end up, on a workbench.

Note the twin hammers 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 mechanism sitting upright on workbench, slowly rotate Anvil in a clockwise direction until it comesup solid.

If you continue to rotate the Anvil, it will cam the Hammers out of engagement. Do not allow this to happen; merely rotate the Anvil until it comes up solid.

3.Hold Hammer Frame firmly and without disturbing the hammers, gently lift Anvil simultaneouslyrotating it clockwise about 1/8 of a turn from the Hammer Frame.

The twin hammers are now free to slide from the Hammer Frame when the Hammer Pins are removed. Do not drop the Hammers (33).

4.With Anvil removed, lift out the two Hammer Pins.

5.Remove the Hammers.

2.Grasp splined end of Rotor (18) and pull assembled motor from Motor Housing (1).

3.Lift Front End Plate (26) and Front Rotor Bearing

(20)from splined end of the Rotor.

4.Remove Cylinder (22) and Vanes (25).

5.Remove Rear Rotor Bearing Retainer (21).

6.Lift Rear End Plate (27) and Rear Rotor Bearing (19) from Rotor.

7.Unscrew Air Strainer (6) and remove it.

8.Withdraw Throttle Valve Spring (4), Throttle Valve (2), and Throttle Valve Stem (5). Remove Throttle Valve Face (3) from Throttle Valve.

9.Remove Trigger Pin (8) and Trigger (7).

10.Unscrew Reverse Valve Knob Screw (15) and remove Reverse Valve Knob (14).

This Screw is installed with a quality thread-locking compound. You may have to heat it slightly to loosen the Screw.

11.While slowly rotating Reverse Valve (11), withdraw it from Reverse Valve Bushing (9).

Be careful not to lose the Reverse Valve Detent Ball

(12)and Spring (13) from the hole in the side of the Reverse Valve.

Assembly

General Instructions

1.Always press on the inner ring of a ball-type bearing when installing the bearing on

2.Always press on the outer ring of a ball-type bearing when installing the bearing in

3.Whenever grasping a tool or part in a vise, always use leather-covered or

4.Always clean every part and wipe every part with a thin film of oil before

5.Apply a film of o-ring lubricant to all O-rings before final assembly.

6.Check every bearing for roughness. If an open bearing must be cleaned, wash it thoroughly in solvent and dry it with a clean cloth. Sealed or shielded bearings should never be cleaned.
