4.
Remove six flange nuts which secure hopper inlet guide to impeller housing.
See A in Figure 12.
5.
Carefully separate the hopper assembly from the impeller housing and set
it aside.
6.
Insert a piece of wood into the chute deflector opening to stabilize the
impeller and prevent it from rotating when removing the shredder blade.
7.
Remove the two internal hex screws, hex lock nuts, and lock washers which
secure the shredder blade to the impeller. See B in Figure 12.
NOTE: Use a 3/16" hex key (Allen) wrench on the outside of the shredder
blade and a 1/2" box (or socket) wrench on the inside of the shredder blade.
Hold the Allen wrench stationary and rotate the box (or socket) wrench to
loosen the nut.
8.
Remove the hex bolt, lock washer, and flat washer to completely free
shredder blade. See C in Figure 12.
IMPORTANT: If sharpening the blade for reuse, follow the original angle of
grind as a guide. Make certain each cutting edge receives an equal amount
of grinding to prevent an unbalanced blade. Remove metal from the heavy
side until it is balanced evenly.
IMPORTANT: When reassembling the blade, tighten center bolt to between
45 ft.-lbs and 58 ft.-lbs and the two out bolts to between 20 ft.-lbs and 25
ft.-lbs.
