3.
Lay a bead of Ingersoll–Rand No. 28 Grease,
approximately 2 to 3 cc, on top of the Clutch Balls
and then bring the Clutch Shaft and Cam Jaw
together capturing the Balls between them.
4.
While holding the Shaft and Jaw together, slide the
Clutch Cam Ball Driver (71), large end leading, onto
the Clutch Shaft until it is against the Cam Jaw.
5.
Rotate the Driver to align the large hole through one
wall of the Driver with the comparable size opening
of the cross hole through the Clutch Shaft. Push the
Clutch Cam Ball Driver Retaining Pin (73) into the
hole to lock the Driver in position on the Clutch
Shaft.

Slide the Cam Ball Seat (74), large end leading, onto
the Shaft against the Balls. Follow with the Clutch
Spring (75), Spring Seat (76), Thrust Bearing (77)
and the Clutch Adjusting Nut Washer (78) with the
smooth face leading.
9.
Thread the Clutch Adjusting Nut (79), smooth face
trailing, onto the Clutch Shaft.
10. Insert the tip of a #1 Phillips Head Screwdriver into
the adjustment opening between the Clutch Adjusting
Nut and the Clutch Adjusting Nut Washer. Rotate the
screwdriver counterclockwise and thread the
Adjustment Nut onto the Clutch Shaft until the
external groove for the Clutch Adjusting Nut Stop
(80) is visible.

containing the Return Spring.
6.
Push on the pointed end of the Shutoff Pin to depress
the Spring while inserting the Automatic Shutoff

Using a small screwdriver, work the Spindle Bearing
Seat (91) into the internal groove nearest the notched
