the complete assembly from the tool. Using the 4 mm hex wrench
supplied with the unit, loosen both adjusting screws (45992) -
NOTE: Alternately unthread adjusting screws approximately 1/2
turn at a time or unthread screws simultaneously to prevent dam-
aging the unit.
Pack bearings and coat gears with a good grade of bearing
grease when assembling. Saturate oil reservoirs with a good mul-
tigrade 10W/30 oil.
After the body and components have been removed from the
adapter, driving spindle (47757-302) and components can be re-
moved from adapter. To remove bearing (32325) and/or gear
(45991); remove retaining ring (45989), press bearing back on
spindle to expose needle roller (45986) and remove roller to re-
move gear. Remove bearing from spindle.
Insert a dummy adjusting screw (45992) (or a shaft of the same
diameter) thru adapter side of body to maintain alignment of parts
to be assembled into body and assemble nylon washer (45994) to
dummy screw. Assemble one bearing (46002), spacer (46995)
and another bearing (46002) into gear (45996) and assemble
gear to the dummy screw. Assemble nylon washer (45993) into
body, bending washer slightly to insert into body, and assemble oil
reservoir (46009) into body.
To remove gear (45996) and/or components, remove crescent
ring (45997). Rotate spindle turret, and at the same time, pull back
slightly on turret to locate alignment of spindle with notch in body
(45999) and remove spindle assembly from body. To remove gear
(45996) from body, remove oil reservoir (46009) and nylon wash-
er (45993) bending washer slightly to remove. Bearings (46602),
spacer (45995) and washer (45994) are loose parts and will drop

semble nylon washer (45994) to adjusting screw. Assemble the
spindle assembly into body while holding adjusting screw in align-
ment with dummy screw to maintain pans alignment and using
adjustment screw to push the dummy screw out of body. NOTE:

sembling spindle to body, assemble crescent ring (45997) to ad-
justing screw, securing screw to body.

Insert bit into spindle and into locking insert (where applicable) in-
should be approximately 5/16” (8 mm) long and the depth should
suring that one of the set screws locates squarely on the flat of the
be 1/3 of the bit diameter. NOTE: If bit is too large to fit into locking
bit. Tighten Collet firmly, then tighten set screws. NOTE: DO NOT
