q . Apply a thin coat of light oil on the threads of the drive shaft and the bottom surface of the grip spring
locknut.
r . Thread the grip spring locknut (61) onto the end of the drive shaft (finger tight). Rotate the internal gear
(30) by hand, and at the same time tighten down on the locknut until the internal gear can no longer
be rotated. Tighten the locknut securely. (The table below lists the recommended tightening torque
for this locknut. If a torque wrench is not available, be sure locknut is tightened sufficiently to prevent
grip spring slippage.) Use one of the following methods to prevent the drive shaft from turning while
performing this operation.
XJQ SERIES MODEL 30 & 43 65 thru 117 174 thru 350
TIGHTENING TORQUE (FT.–LBS) 20 50 125
RECOMMENDED TIGHTENING TORQUE FOR GRIP SPRING LOCKNUT
1 .Procedure for units equipped with chuck:
a .XJQ 30 thru 117 – Reassemble the chuck assembly. Insert a hex key wrench into the chuck
screw.
b .XJQ 174 thru 350 – With the chuck assembly removed from the drive shaft, insert a 1 foot length
of 1 inch diameter bar in the chuck grip bore.
2 .For models with coupling:
a .Bolts can be inserted into the coupling half and a bar interlocked between the bolts to keep the
drive shaft from rotating.
7.3 Assembling the Pinion on the Motor Shaft:
a . XJQ 174 thru 350 ONLY:
1 .Install the slinger on the motor shaft, allowing a gap of 1/32 inch gap between the motor oil seal and
the top of the slinger.
2 .Check shaft end play and rotate to make sure slinger rotates freely.
3 .Coat the set screw threads with Loctite and tighten the set screw securely.
b . Apply a thin film of grease to the motor shaft or pinion shaft.
c . Make sure that the motor shaft key (46) is in place in the motor shaft keyway.
d . Assemble the pinion on the motor shaft by driving it into place with light strokes of a mallet.
e . Make sure that the pinion and motor shafts butt securely, then install and tighten the pinion screw (4).
7.4 Assembling the Chuck:
a . Assemble chuck washer (18), chuck grip (34) and snap ring (21) on the chuck screw (8).
b . Thread the chuck screw into the chuck end of the drive shaft, far enough to insert the limit pin (11), so
that the end of the pin is 3/16 of an inch underflush.
7.5 Assembling the Motor to the Housing:
a . Fill the gear chamber of the housing (36) level with a suitable lubricant (see Section 5). Make sure that
the grease is solidly packed without air pockets by paddling the grease, rotating the drive shaft by
hand, tapping or shaking the housing.
