Replacing Belt
To replace the belt, follow the procedures for “Belt
Tension Adjustment” preceding this subsection and
decrease the belt tension additionally to allow the belt to
slide over the top sprocket.
NOTE:
When replacing or installing a new belt, align
the grooves in the belt with the upper and lower
pulleys.
Install the belt and adjust the tension accordingly. Refer
again to the “Belt Tension Adjustment” procedure and
follow the instructions completely.
Sprocket Removal
The steps to remove either the upper or lower sprocket
are identical. For this procedure the upper sprocket is
discussed. Follow the same procedure to remove the
lower sprocket.
NOTE:
See page 33 for an exploded view and parts
listing for the belt/sprocket combination.
1. Disconnect or turn off all power to the Battle Ax.
DANGER:
Shut down and lock out power
from the excavator before removing
sprockets. Failure to do so could result in
serious injury or death.
Remove the drive belt by following the instructions in
“Belt Tension Adjustment” and “Replacing Belt” on
page 21.

2. Remove the three screws (1) from the taper lock
bushing (2) of the sprocket (3).
3. Insert two of the screws into the threaded holes (4).
4. Tighten the two screws until bushing grip is released.
(If excessively tight, lightly hammer face of sprocket
using drift pin or sleeve).
NOTE:
Never hit sprocket directly with hammer.
5. Replace the sprocket by cleaning the shaft, bore of
bushing, outside of bushing and hub bore of all oil,
paint and dirt. File away any burrs.
6. Insert bushing into hub. Match the hole pattern, not
threaded holes (each complete hole will be threaded
on one side only).
7. Apply a thread-locking compound to screws and
thread into the three opposing holes.
8. Position assembly on shaft and alternately torque
screws to 35 ft.-lbs.
9. To increase gripping force, hammer face of bushing
using drift or sleeve.
NOTE:
Do not hit bushing directly with hammer.
10. Re-torque screws after hammering.
11. Recheck screw torque after initial run-in, and
periodically thereafter, repeat steps 4, 5 & 6 if loose.
12. Check alignment of the sprocket. Repeat sprocket
removal and assembly procedures if necessary.
