Shredding Hammer Rotation and

Replacement

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.

Triangular hammers can be rotated twice after the first

edge dulls, then flipped over once and rotated again for a

total of 6 edges. J-hammers can be flipped over once for

a total of two cutting edges.

To rotate the shredding hammers:

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.

WARNING

To avoid serious injury from accidental starting,

always disconnect the spark plug wire and secure it

away from the spark plug when servicing the unit.

3. Detach the shredder hopper from the rotator housing

(Figure 12).

4. Remove the rotator cover by removing the hardware

that secures it to the main housing (Figure 13).

5. Note the assembly sequence of the hardware used to

secure the hammers (Figure 14). Using a 5/16" allen

wrench remove the socket head capscrew (A) and

related hardware.

7. inspect the hammers (G, H), spacer tubes (D, F), and

hardware. If the spacer tube (D, F) shows signs of

wear, replace it. inspect and flip, or replace the

hammers (G, H).

8. Reassemble the hammers, spacers, washers, and

capscrews. Torque the socket head capscrews (A)

to 30-35 ft. Ibs. (41-47 N.m.)Refer to Figure 14 for

assembly. The J-hammer (G) on the opposite side of

the rotor faces outward for balanced rotation.

Repeat for all the hammers.
