The Rectangular Shredder Knife Kit is a replacement kit to
replace existing dull or damaged knives. The serrated shred-
der knives are designed to offer long life and can be reversed
if they become dull. To remove the knives or to install a
complete new shredder kit proceed as follows.
INSTALLATION STEPS:
1. Remove belt guards from under engine frame, remove
discharge cover and screen.
2. Remove #10-24 nuts and bolts from knife shafts.
3. Align shaft with 5/8” hole in rear of frame and small hole
in front of machine by the chipper chute.
4. Using a small punch or rod drive the shaft towards and
out the rear 5/8” hole.
5. To assemble, insert shaft through the 5/8” hole in rear of
frame and slide knives and spacers in their proper order
(see drawing) onto the shaft. Install a new # 10-24 nut
and bolt.
6. Repeat steps 3 through 6 to assemble the other three
shafts.
7. When completed install discharge screen, and dis-
charge cover, torque all 3/8” bolts to 33 ft lbs. and test
run machine.
This shredder kit uses an improved knife pattern to pro-
vide more complete shredding, durability, and easier feed-
ing. Insure the knives and spacers are installed properly
to maintain rotor balance.
NOTE
The serrated edge of the shredder knives should face the
same direction as the cutting edge of the chipper blades.
Never reuse the #10-24 nut and bolt, always install new
parts when repairing. Never reuse shafts or spacers if
they show signs of wear or abuse. Install new ones.
