Installation (Fig. 19)
CAUTION
To prevent personal injury, make sure that chop-
per assembly is properly supported as it is
installed to the machine. Chopper assembly
weighs approximately 125 pounds (57 kg).
1. Install chopper assembly into machine from the rear
of the machine. Clean chopper axle ends and apply a
light film of oil to shaft ends.
2. On both sides of machine, install bearing and end-
plate:
A. If removed, attach bearing to endplate with four
(4) carriage screws, flat washers and lock nuts.
B. Slide endplate with bearing onto chopper axle.
C. Align holes in endplate and machine frame. Se-
cure endplate in position with seven (7) carriage
screws and flange nuts.
3. Rotate chopper assembly a few times and center
chopper between bearings. Secure chopper axle in
bearings (see Flange Bearing Service in this section).
4. Position reinforcing ring (item 8) to chopper housing
and secure with removed fasteners (Fig. 22).
IMPORTANT: When installing pulleys and drive
belts, make sure to properly align drive, driven and
idler pulleys.
NOTE: When installing pulley on left end of chopper
axle, align pulley and drive belts with drive pulley on jack
shaft.
5. Install square key, pulley, taper lock bushing and
drive belts to left end of chopper axle (see Pulley Assem-
bly Service in this section).
6. Install square key, sprocket and drive belt to right end
of chopper axle:
A. Apply antiseize lubricant to square key and place
key in chopper axle slot.
B. Slide sprocket onto chopper axle. Do not tighten
set screws in sprocket.

IMPORTANT: Make sure that brush shaft and
chopper axle are properly aligned as drive belt is
installed (Fig. 23). Improper alignment will de-
crease machine performance and may lead to in-
creased debris buildup in Processor that can
cause accelerated component wear and dam-
age.
C. Rotate chopper axle so that a row of chopper tips
is aligned with the brush housing corner. Rotate
brush shaft so that one of the brush tips is aligned
with the rotating corner shaft (Fig. 23).
D. After positioning chopper axle and brush shaft,
install drive belt to sprocket on chopper axle and driv-
en pulley on brush shaft. Keep shafts properly
aligned as drive belt is installed.
NOTE: When positioning pulley onto the right end of
chopper axle, align pulley and belt with driven pulley
on brush shaft.
E. Using a straight edge across the face of the brush
shaft driven pulley, move sprocket on chopper axle
so that drive belt and straight edge are aligned indi-
cating correct position of sprocket.
F. Apply Loctite #242 (or equivalent) to threads of
set screws (item 15). Install and tighten set screws
into sprocket to secure sprocket to chopper axle.
