Disassembly
1. Using the proper allen wrench, loosen the set screw(s)
in the coupling.
2. With the correct size wrench, loosen and remove the
four bolts which hold the motor to the discharge sec-
tion of the pump end motor support.
3. Move the motor straight back until the shaft is free
from the coupling.
Assembly
1. If not already done, disconnect the motor stool
from the pump volute by removing the cap screws
which join the two together. Carefully pull the motor
stool and rotating assembly out of the pump volute.
2. Thoroughly clean the surfaces of the motor and pump
end mounting flanges.
3. Place the stub shaft onto the end of the motor shaft.
Connect the motor and motor stool by inserting the
mounting bolts and tightening them diagonally and
evenly (torque 15 to 20 ft. lbs.).
4. Using the appropriate edge of impeller spacing tool
SV00201 (see Table C), position the impeller at the cor-
rect axial location and tighten allen shaft set screw(s)
into the motor shaft’s keyway (see Figures 5A, B & C).
5. Attach the motor stool to the pump volute with the
cap screws, ensuring that the terminal box or conduit
connection and the pump’s discharge port are correctly
oriented for your installation. Replace the attaching cap
screws and torque to 25 ft. lbs.
6. Be certain the pump shaft can be rotated by hand. If
shaft cannot be rotated or it binds, repeat steps 4 and 5.
