SERVICE INSTRUCTIONS
TRIP ROD SIZING
A. Old Trip Rod
The tool should be reassembled complete less the trip rod,
clutch, and clutch housing. With the air on, install the trip
rod and clutch into the tool and measure the distance
between the rear face of the ball retainer, No. 867881, and
the front face of the gear case. Turn the air off and depress
the clutch assembly and measure clutch travel. Clutch
travel must be at least 3/16". If not, the trip rod should be
replaced.
B. New Trip Rod
Assemble the tool completely, less the clutch housing, and
connect the tool to the air supply. Screw (left hand threads)
the clutch housing onto the gear case until air exhausts
from the backhead. Measure the gap between the clutch
housing and gear case. Grind this amount plus 5/64" off the
trip rod.
SAFETY CHECK
After repair or replacement of parts, tools equipped with an
automatic shut-off device should be tested at low torque
and 90 p.s.i.g. to verify that the device is functioning
properly.
