Disassembly
1. Shut off the power to the motor
before disconnecting any
electrical wiring from the back of the
motor.
2. Disassemble the volute from the
bracket motor assembly by removing
the seven ¼ 20 x 2 ¾ cap screws.
(The volute may be left in-line if you
wish.)
3. Remove the cap covering the back
end of the motor shaft and with a large screwdriver or wrench, prevent shaft rotation while
unscrewing the impeller counterclockwise.
4. Remove the ceramic piece from the impeller hub.
5. Detach the bracket from the motor by removing the four 3/8” cap screws, and slide it forward,
away from the motor.
6. Remove the carbon-graphite seal from the bracket by pressing it out from the back. Do not dig
it out from the front!
Pump End Assembly
1. Check all pump parts and clean as needed.
2. If the motor shaft has corrosion build up, use emery cloth to clean it.
3. Install the O-ring into the O-ring gland in the bracket bore.
4. Press the carbon seal head into the bracket bore. CAUTION! Press only on the stainless steel
or polypropylene shell, NOT ON THE DELICATE CARBON FACE! DO NOT TOUCH THE
CARBON SEAL FACE!
5. Note: It is not recommended to use a slinger in conjunction with a PVC shaft sleeve.
6. Mount the bracket onto the motor C-face using four 3/8” cap screws and tighten them snugly.
7. Press the ceramic into the impeller hub. It helps to moisten the rubber boot with water first.
The ceramic MUST SIT FLAT. If one side is higher than the other, the seal will leak! The
smooth face must be up and exposed.
8. Screw the impeller clockwise onto the motor shaft and tighten. You can hold the shaft
stationary at the opposite end of the motor with a large screwdriver or wrench..
9. Place the large O-ring in the groove in the volute. Note: It is easiest to lay the volute, suction
side down, place the O-ring in the groove, and lower the bracket/motor assembly down onto
the volute. (So the O-ring doesn’t pop out.)
10. Install the seven 1/4” x 2 3/4” socket cap screws with washers and tighten in a cross pattern
until they are reasonably snug. (No need to overtighten).
11. Place the small O-rings onto both drain plugs, and screw them into the 1/4” holes in the
volute and bracket.
