ROTOR REMOVAL

NOTE: The rotor does not need to be removed to change the
hammers and knives. However, the removal and installa-
tion of the knives will be easier with the rotor removed.
NOTE: If using a unit that has socket head bolts with no locking
plates on them, the hardware will need to be upgraded to new
hardware kit.
To remove the rotor from the drive shaft:
1. Turn the engine off and wait for all moving parts to stop.
2. Disconnect the spark plug wire and secure it away from the
spark plug. SEE FIGURE 15.
3. Detach the rotor housing and hopper from the rotor plate.
SEE FIGURE 16.
4. Bend the side tabs away from the center mounting bolt and
remove the bolt.
5. Carefully remove the rotor plate, spacer, and key from the
crankshaft. SEE FIGURE 17.
HAMMER REMOVAL AND INSTALLATION
NOTE: The cutting edges of the shredding hammers may
eventually wear out requiring rotation of the hammer or
replacement if all cutting edges have been dulled.
NOTE: Triangular hammers can be rotated twice after the
first edge dulls, then flipped over once and rotated again
for a total of six edges. J-hammers can be flipped over
once for a total of two cutting edges.
1. Remove the hammers by first bending the lock plate
tabs down away from the hex head bolt securing the ham-
mers. Remove the bolt. SEE FIGURES 18 AND 19 (next page).
NOTE: The assembly sequence of the hardware used to
secure the hammers.
2. Inspect the hammers, spacers, and hardware. If the spacer
tube shows signs of wear, replace it. Inspect and flip, or
replace the hammers. The lock plate should always be
replaced when replacing or rotating hammers.
3. Inspect the hammers, spacers, lock plate and bolts. Torque
the bolt to 30-35 ft -lb (41-47 N.m.). The J-hammer on the op-
posite side of the rotor faces outward for balanced rotation.
