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

Disassembly of the Impact Mechanism
1. Wash impact mechanism in a suitable solvent to clean as much
grease as possible from it.
2. Place impact mechanism on an arbor press so it is supported on
the hammer jaws and so Arbor is free to move downward.
3. Press on end of Ball Cam (46) until Cam Balls (45) drop out of
holes in side of Hammer.
4. Ease up on the handle of the arbor press.
5. Lift Ball Cam from Hammer. Friction Drive Washer (49) may come
off with the Ball Cam or it may stay on rear face of Arbor.
6. Grasp Hammer Spring Thrust Bearing Race (43), and being careful
not to drop the seventeen Hammer Spring Thrust Bearing
Balls (44), lift Arbor and Bearing Race from the bore of Hammer.
7. Lift Hammer Spring (48) from bore of Hammer.
Disassembly of the Motor
1. Grasp Dead Handle (29) horizontally in a vise so Grip Handle (15)
is upward.
