3.
Attach the Reverse Valve Knob (21) to the Reverse Valve with the
Reverse Valve Knob Screw (22)and tighten the Screw to 40 to 50 in-
lbs (4.5 to 5.6 Nm) torque.
Assembly of the Motor
1.
Using a sleeve that will contact only the outer ring of the bearing,
press the Front Rotor Bearing (34) into the Front End Plate (33) and
the Rear Rotor Bearing (26) into the Rear End Plate (27).
2.
Slip the Front End Plate and Bearing over the splined hub of the
Rotor.
3.
Grasp the splined hub of the Rotor in leather-covered or copper-
covered vise jaws so the Rotor is in a vertical position.
4.
Dampen each Vane (29) with light oil and insert a Vane into each
vane slot.
5.
Set the Cylinder (30) over the Rotor and onto the Front End Plate.
6.
Slide the Rear End Plate and Bearing onto the rotor hub and against
the Cylinder.
7.
Install the Rear Rotor Bearing Retainer (25) in the groove on the rotor
hub.
8.
Wipe a thin film of light grease on the End Plate Gasket (24) and
press the Gasket firmly against the Rear End Plate.
9.
Align the dowel hole in both End Plates with the one through the
Cylinder and insert a guide rod 5/32’’ (4.0 mm) diameter x 6’’ (152
mm) long. Allow the rod to protrude from the Rear End Plate and End
Plate Gasket.
10. Grasp the handle of the Motor Housing (1) in leather-covered or
copper-covered vise jaws so the bore of the Motor Housing is
horizontal.
11. Insert the protruding end of the guide rod into the dowel hole in the
bore of the Motor Housing and slide the motor along the rod until it is
completely seated.
12. Remove the guide rod and replace it with the Cylinder Dowel (31).
13. Reposition the Motor Housing in the vise so the open face of the
Motor Housing is upward.
14. Place the two Motor Clamp Washers (35), convex side first, against
the Front End Plate so the inner rim of the leading Washer contacts
the End Plate and the outer rim of the trailing Washer contacts the
Hammer Case Pilot (43).
15. Place the Rear Hammer Frame Washer (38) over the hub of the
Rotor and against the Front Rotor Bearing.
Assembly of the Impact Mechanism
1.
Coat the spline and pin holes of the Hammer Frame (36) with a light
film of
Ingersoll-Rand
No.100 Grease. Position the Hammer Frame
on a workbench, splined end down.
2.
Coat the Hammer (39) with a light film of
Ingersoll-Rand
No.100
Grease and slide the Hammer into the Hammer Frame.
3.
Coat the two Hammer Pins (37) with a light film of
Ingersoll-Rand
No.100 Grease and insert the Pins into the two pin holes of the
Hammer Frame so they engage the notches on the Hammer.
4.
Coat the Anvil (46) or (49) with a light film of
Ingersoll-Rand
No.100
Grease. Slide the Anvil into the Hammer Frame and through the
Hammer until it seats.
5.
Set the assembled impact mechanism down over the splined hub of
the Rotor.
Assembly of the Air Impact Wrench
1.
Position the Hammer Case Gasket (42) against the face of the Motor
Housing.
2.
Smear a thin film of
Ingersoll-Rand
No.100 Grease on the inside
surface of the Hammer Case Bushing (41) and place the Hammer
Case (40) down over the Anvil (46) or (49) and against the Motor
Housing.
3.
Install the Hammer Case Cap Screws (45). Tighten the Hammer
Case Cap Screws to 60 to 70 in-lb (7.0 to 8.0 Nm) torque.
