MODEL 12X MAINTENANCE
Proper installation is critical to bearing life.
Improper installation could cause premature or
immediate failure. Particular care must be taken not
to create a preload on the bearings while tightening
the locknut. Use of a good quality torque wrench
is also important to your safety as well as proper
bearing installation.

1. Clean the shaft so that it is free from burrs and
rust. Do not coat the chipper shaft or the bore
of the bearing adapter with a preservative,
lubricant, or other substance such as Loctite
®
.
2. If the adapter sleeve happens to get removed
from the bearing during installation, the locking
pin in the adapter sleeve must be aligned with the
keyway in the inner bore. See Figure 1.
3. Position the bearings on the shaft to their
intended position. If the bearings do not slide
freely on the shaft, loosen the locknut until the
bearing does.
4. Keep the weight of the drum head off the
bearings while bolting the bearings down.
5. Center the chipper drum inside the base and
bolt the bearing down on the radiator side of the
machine and torque the four bearing bolts to
220 ft.-lbs. (298 Nm).
6. Offset the chipper drum approximately 1/8”
(3.2mm) from center of the base to the drive
side of the machine.
7. Hand tighten the locknut to take out the
looseness, then use a hook type spanner wrench
to bring the locknut to a snug fit.
Before attempting any type of maintenance,
disengage clutch, wait for the drum to come to a
complete stop, turn off engine, remove the ignition
key, make sure the ignition key is in your possession,
install the drum lock pin, and disconnect the battery.
SAFETY INSTRUCTIONS NOTICE
8. Mark the locknut and chipper drum shaft with
a grease pencil or a dark marker. Use a soft
steel drift pin and a hammer to drive the locknut
clockwise one full turn. Make sure the adapter
sleeve does not turn on the shaft while tightening.
If the adapter sleeve is turning, it can be held by
placing a hook type spanner wrench in the split
area of the sleeve.
9. Offset the bearing on the left side of the machine
about 1/8” (3.2mm) from its intended position
towards the base, so when the bearing is
tightened up on the shaft, the bolt holes will line
up.
10. Repeat steps 7 - 8 to tighten the right side
bearing on the shaft.
11. Loosen all the bearing bolts to release the
preload on the bearings if there is any. Bolt both
bearings down and torque the bolts to 220 ft.-lbs.
(298 Nm).
12. If the drum head does not spin freely, there is a
preload on the bearings. The bearings will need
to be completely loosened and steps 3 - 11 need
to be repeated.
13. Torque the set screws in the locknut of both
bearings to 13-15 ft.-lbs. (18-20 Nm) with a 5/32”
hex type torque wrench.
