PART 4 MAINTENANCE
Pulper Seal Replacement
Remove the fasteners holding the sizing ring. Use
2 fasteners as jack screws in the threaded holes
180 degrees apart on the sizing ring face. Once
freed, remove the ring. Remove the Cutting Disk,
by wedging a piece of wood between the cutting
disk and tank bottom to prevent spinning. Loosen
and remove top bolt and 4 radial bolts from center
cap. Remove center cap. Pull cutting disk straight
up. Be careful to not lose the square key. Once
removed, the cutting disk should contain the upper
seal. Slide this off and discard. Clean shaft of
debris. Carefully pick out lower magnetic seal from
bore and discard.
Magnetic seals should remain in packaging until
ready for installation in unit. When inserting the
seal in place, make sure no dust or foreign matter
are attached to the seal. Make sure the seal cavity
is clean of debris. Make sure there are no sharp
objects on any contact parts.
When the seal is removed from packaging, the ro-
tor portion of the seal (seal case) must be sepa-
rated from the magnet. Pull seal case
straight
away
from magnet. Discard paper separator.
MAKE SURE THAT YOU DO NOT INSERT THE
LOWER SEAL UPSIDE DOWN! Each half of the
seal should face each other as they did in the origi-
nal packaging. The highly polish surface of the bot-
tom seal faces the magnet surface of the upper
seal.
Caution: To prevent damage to mating faces, do
not slide seal case across magnet. Avoid placing
magnet in area where small metal chips might be
attracted by the magnet.
Remove o-rings and completely lubricate with a
thing film of lubricant and reinstall into grooves.
Apply a thin film of lubricant to the o-ring sealing
surfaces in the bore and on the shaft
Press lower seal into bore gently with the polished
magnet face position upward. Do not use any tools
to do so. Verify that no debris is on the seal face.
Gently slide the upper seal on the cutting disk shaft
so that it is no more than 3/4” from the shaft bot-
tom. Make sure the seal is correctly oriented with
the magnetic surface facing outward away from the
disk.
Gently slide the cutting disk onto the motor shaft,
aligning keyway to key, and lower slowly in one
motion. Once the cutting disk has been lowered,
DO NOT PULL UP ON THE DISK.
If any upward
motion is imparted on the cutting disk, the magnetic
seals will separate, and will not seal! The installa-
tion process must be started over by removing the
cutting disk completely and sliding the upper seal
down to within 3/4” from the shaft bottom.
