Toro ProCore Processor Service Manual page 95

Chopper tips and blade assemblies can be removed
and installed with the chopper axle mounted in the ma-
chine.
Disassembly (Figs. 16 and 17)
1. Park ProCore Processor on a level surface with the
Processor fully lowered. Make sure that Processor en-
gine is off. Remove key from the ignition switch. Chock
wheels to prevent movement of the machine.
NOTE: The RH and LH blade assembly use the same
blade but differ in which holes are used to mount the
chopper tip to the blade (Fig. 18). Blades that have the
chopper tips mounted toward the right side of the ma-
chine are RH assemblies. Blades that have the chopper
tips mounted toward the left side of the machine are LH
assemblies (shown in Fig. 17). Before removing chop-
per tip from blade, note which blade holes are used for
proper attachment of chopper tip.
NOTE: The screws used to secure chopper tip to blade
have a patch lock. To ease screw removal, apply heat to
thread area of chopper tip while removing screw.
NOTE: If a screw used to secure chopper tip to blade
has broken, remove chopper blade from chopper axle.
Make a slot in the screw end that protrudes beyond the
chopper tip. Apply heat to thread area of chopper tip and
use a flat blade screwdriver to remove the broken screw.
2. To remove chopper tip(s) from blade, use a ratchet-
ing box wrench to remove two (2) screws that secure tip
to blade.
3. To remove chopper blades from chopper axle, re-
move two (2) cap screws and lock nuts that secure right
and left blade assemblies to axle. Remove blade as-
semblies. Note that notch on both blades align (Fig. 18).
Assembly (Figs. 16 and 17)
1. Inspect threads of chopper tip(s). If necessary, clean
threads in tip(s) with a 5/16 -- UNC tap.
IMPORTANT: Due to the patch lock feature of the
screws used to secure the chopper tips to the blade,
it is recommended to replace the screws after disas-
sembly. An alternative would be to apply Loctite
#242 (or equivalent) to the threads of the original
screws before assembly.
2. Secure chopper tip(s) to correct holes of chopper
blade with two (2) screws. Torque screws from 270 to
330 in- -lb (31 to 37 N- -m).
3. If blades were removed from axle, secure RH and LH
chopper blades to chopper axle with two (2) cap screws
and lock nuts. Make sure that notch on both blades align
(Fig. 18).
