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. lbs. (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.
