REASSEMBLY — GENERAL

The tool is reassembled in the reverse order of disassem-
bly. Clean all parts thoroughly in kerosene and inspect for
damage or wear. Check all bearings for wear which can be
detected by excessive end play and/or roughness which
would indicate a brinelled condition. The rotor blades should
be replaced at every repair cycle if they measure less then
1/4" (6.4mm) at either end. All gear teeth, bearings, and pins
should receive a close inspection and be replaced if neces-
sary.

NOTE: During reassembly of the complete tool, it is impor-
tant that the motor be free. After the tool is completely
assembled, the right angle square drive spindle should turn
freely using a small hand wrench. If the spindle does not turn
freely, the motor should be checked for proper spacing. Do
not run the tool until the spindle turns freely. Failure to do this
could result in damage to motor components.

Motor Unit

Install the rear rotor bearing into the rear bearing plate.
Make sure the outer bearing race is firmly seated in bearing
plate. Clamp the rotor lightly in the vise with the threaded
end up and slip the rear bearing plate assembly onto the
rotor shaft far enough for the bearing lock nut to start.
Tighten the lock nut until there is approximately .0015"
clearance between the rotor and bearing plate. The outer

bearing race should be firmly seated and the rotor held
forward when checking this clearance.

Pack both rotor bearings with a good grade of No. 2 Moly
grease after assembly of the motor unit.

Gear Train
When installing the spider assembly the idler gears must be
aligned with the pockets machined in the ring gear. Line up
the hole in the ring gear with the hole in the transducer and
install the pin, No. 812164.

Transducer Wiring Connection

NOTE: Do not bend, strike, push or pull the transducer on
the plastic coated area of the transducer. Connect the cable
connector, No. 202183, to the transducer and wrap the
wiring around the transducer until the cable connector is one
(1) wrap past the connection and then thread the connector
thru the hole in the transducer. Install the transducer on the
motor housing, feeding the connector thru the hole in the
housing. Line up the tangs on the transducer with the
grooves in the housing being careful not to pinch the
connector.

Right Angle Head

During reassembly of the gear train and angle head, all of
the various gears and bearings should receive a generous
amount of NLGI 2-EP grease. The pinion needle bearing
should be slipped onto the pinion gear and then pressed into
the right angle housing until the rear of the bearing is flush
or slightly below the step in the housing.

NOTE: During reassembly of the "T" right angle head, the
bearing cap, No. 867509, should be torqued to 100-110 ft.
lbs. Also, the bearing cap lock screw, No. 867997, should be
torqued to 10 in. lbs. minimum.

Pour a few drops of 10W machine oil into the air inlet after
complete assembly to ensure immediate lubrication of all
motor parts when air is applied.

SAFETY CHECK

After repair or replacement of parts, tools equipped with an
automatic shut-off device should be tested to verify that it is
functioning properly. The torque setting entered into the
torque control monitor must not exceed maximum torque
range or tool will stall and not shut-off.

SERVICE INSTRUCTIONS

Must be replaced if 
7/32" (5.6mm) or less 
at either end.
