Maintaining the Shredder Hammers
When the hardened steel Hammers become dull or round on the cutting edge, they should be rotated or reversed.
Note:
The four flat Hammers have four cutting edges and the four J Hammers have two that may be used before replacement is
necessary. To reverse the Hammers, proceed as follows:
Tools and Part Required
1/2" Wrench
3/8" Wrench
5/32" Allen Wrench
1.
Remove the Hammermill Housing/Shredder Hopper Assembly. See
“Replacing the Chipper Knife” in this Chapter.
2.
Use a 5/32" Allen Wrench and a 3/8" Wrench to remove the Screw and
Locknut from one of the Short Spacers (
Figure 30
).
3.
Remove the Hammer Shaft, Spacers and Hammers.
4.
Flip the J Hammer and Flat Hammer 180 degrees making sure the order is
correct (J Hammer outermost).
Note:
Be sure you
reinstall the Hammers and Spacers in exactly the same order
that they were removed.
5.
Reinstall the Screw and locknut through the Short Spacer and the Hammer
Pin.
6.
Repeat steps 2 through 4 for the other three sets of Hammers. Confirm
that two of the J Hammers are facing out and the opposite two are facing
in (
Figure 31
). Correct them if needed.
7.
Reinstall the Hammer Mill Housing/Shredder Hopper Assembly.
