Lock the rotor by inserting a long
probe into the shredder hopper,
between rotor's hammer shafts.
Loosen the lock collar by removing
the set screw with an 1/8" Allen
wrench. Insert a pin punch at an
angle into the other hole in the
Tap clockwise with a ball peen ham-
mer, turning the collar clockwise, and
remove. (When reassembling, sand
the burr where the set screw enters.
Tap the collar 3-6 times counter-
clockwise with the punch. Unlock
the rotor.)

Remove the flange nuts
the perimeter of the fan housing.
Next, loosen but do not remove
the three flange nuts holding the
triangular flangettes over the bearing.
Pull apart the housings. Then take
off the flangettes and remove the
entire fan housing. Position it under-
neath the unit, as seen in the next
drawing...

Note how the fan housing has been
placed underneath. This supports
the unit while you remove the rotor.
Wedge a screw driver behind the
rotor, under a fan blade and above a
stud. Use a 1/2" wrench to remove
the 5/16" bolt and two lockwashers
from the center of the rotor shaft.
(When reassembling, replace
both lockwashers, and use a torque
wrench to tighten this bolt to 27 ft.-
lbs.)

Pull the rotor from the crankshaft by
pulling and steering the rotor. There
may be some resistance. Pull it off
steadily, making sure that the ham-
mers clear the inner wall of the center
plate.

motor's drive shaft and the key with
liquid graphite. Do not use anti-
