Step 1
SHUT OFF POWER TO THE DISPOSER CONTROL
and remove disposer from service. Remove the top housing
by removing the eight top housing bolts. Remove the center
gasket located on the top of the cutters.
Note:
For easier removal, the top housing can be
left attached to the sink, remove the eight bolts
so that only the disposer bottom comes off. This
eliminates the need to undo the plumbing to the
top housing.
Step 2
Turn the unit upside down so the junction box and
thermal overload covers are facing up and remove both of
these covers. Remove the black rubber gasket over the
thermal overload and pull the thermal overload out of its
seat by pulling on the red button. Remove the o-ring and
push the thermal overload back through the hole so that it is
inside the bottom of the unit.
Step 3
Turn the unit back over and now you are looking
at the cutters. The stationary cutter is the shredder and the
cutter in the middle that spins is the face plate. The piece
under the face plate is the rotor base. Remove the shredder
by inserting a screwdriver in between the face plate and the
shredder and pry it out. Remove the 1-1/4” rotor nut (1-10
hp) or the 3/8” rotor bolt (older style 1 hp). Lift face plate off
the motor shaft, remove the rotor shaft gasket and the rotor
base the same way as the face plate. Next remove the four
screws in the top end bell insert.
Note:
Rotor base might come off attached to the
face plate, if so, separate these parts as the rotor
shaft gasket is located between these parts.
Step 4
Lay unit on its side, use a RUBBER mallet to strike
the large threaded end (7/8-14) of the motor shaft, driving it
out the bottom. The motor rotor will come out with the bot-
tom end bell assembly still attached.
Note:
Verify that Step 2 is complete before com-
pleting Step 4 or the thermal overload wiring may
be damaged.
Step 5
Turn the motor housing upside down and remove the
top end bell insert by pushing it out from inside the motor bar-
rel. After the insert is out, the tolerance ring and o-rings will also
need to be removed if they did not come out with the insert.
Step 6
Using a long screwdriver, drive out the bottom seal
from the motor barrel side of the unit. It will come out similar
to the top end bell insert.
Step 7
Remove the cotter pin and 1/2” castle nut from the
bottom end bell assembly and remove the four washers. Use
a RUBBER mallet to separate the bottom end bell assem-
bly and the motor rotor. Once separated, remove the bottom
sealed bearing and the orange bottom end bell rubber isolator.
You are now ready to install the seal kit.
Items in bold are included in kit.
