DISASSEMBLY
1. Unscrew and remove discharge piping. Remove the six (6) snap ring bolts (
Item 16).
Now the snap ring
(Item 12)
can be removed using a screwdriver or a pair of pliers.
2. With a rubber mallet, gently hit the back of the suction casing (Item 10).
Alternating blows from one side to the other until the suction casing comes off.
Suction casing O-ring can easily be replaced.
3. Unscrew the impeller nut using a 3/4 inch socket wrench in a counterclockwise rotation.
Impeller nut O-ring can be replaced.
4. Thread a 3/4-10UNC bolt into the hole in the center of the impeller eye. Holding the
impeller, using an appropriate wrench turn the bolt clockwise until the impeller slips off
the shaft.
ASSEMBLY
1. Unscrew the fan cover screws and remove the fan, fan cover, and drip shield assembly.
In order for the motor to stand on end, the fan shaft must be placed in a hole deep
enough for it to sit flat on the end bell. With the motor in a vertical position, shaft
upwards, place the four motor spacers over the motor bolt holes. Place housing over
shaft, lining up motor bolt holes in the mounting bracket with holes in the motor. Be
sure the slinger is properly in place. Screw the motor bolts into the holes beneath the
mounting bracket in a diagonal sequence.
Be sure motor screws are tight.
2. Using loctite or other type of thread-locker, secure key into keyway on shaft. Insert the
impeller into the housing. Rotate to engage key and slide or lightly tap into place until
it bottoms out. Do not hammer the impeller and sleeve down on the shaft. Screw the
impeller nut clockwise holding impeller. Be sure impeller nut O-ring is properly in place.
After hand-tight, turn with wrench 180 degrees (10-15 inch lbs).
DO NOT OVERTIGHTEN.
4. Place the pump upright resting on the motor. Look down into the housing and,
while rotating the impeller, check to see that the impeller is centered. The impeller
must not be touching the side of the housing.
5. Lubricate support casing and casing O-ring. Be sure casing O-ring is properly in
place. Slide suction casing over support casing, lining up timing marks to assure
proper fit. Using a soft mallet, tap suction casing down onto support casing until
snap ring groove is exposed. Line up through holes in snap ring with the threaded
holes in the support casing by rotating the snap ring clockwise. Insert and tighten
the six (6) snap ring screws.
