6. Pull the pump suction body forward (see Figure 3). Remove the sleeve
(Ref. No. 9) by pulling it straight forward. Be careful to not damage the
O-rings on the bracket and suction body.
7. Remove the motor canopy. Hold the motor shaft with a 7/16” open end
wrench and remove the nut and two washers (Ref. Nos. 14, 13, 12)
from the end of the shaft. See Figure 4.
8. Slide the impellers and diffusers (Ref. Nos. 11, 10) off of the shaft
(Figure 4).
9. Slide the spacer (Ref. No. 7) off of the shaft, then pull the rotating half
of the seal (Ref. No. 6) forward on the shaft and remove it.
10. Support the motor so that the shaft is free of the weight of the motor
when you loosen the cap screws holding the motor to the bracket.
Remove four cap screws (Ref. No. 2), and slide the motor and shaft out
of the bracket (see Figure 5).
NOTICE: To avoid bending the motor shaft, be sure that the shaft does
not take the weight of the motor as you remove it.

1. Turn the bracket pump side up on the bench. You will need to block it
up to do this (See Figure 7).
2. Clean the seal cavity in the bracket.
3. Wet the outer edge of the rubber cup on the ceramic seat with liquid
soap. Be sparing!
4. Put a clean cardboard washer on the seal face. With thumb pressure,
press the ceramic seal half firmly and squarely into the seal cavity.
The polished face of the ceramic seat is up. If the seal will not seat
correctly, remove it, placing the seal face up on the bench. Reclean the
cavity. The seal should now seat correctly.
5. If the seal does not seat correctly after recleaning the cavity, place
a clean cardboard washer over the polished seal face and carefully
press it into place using a piece of standard 3/4” pipe as a press. See
Figure 7.
NOTICE: Be sure you do not scratch the seal face.
6. Dispose of the cardboard washer and recheck the seal face to be sure it
is free of dirt, foreign particles, scratches and grease.
7. Inspect the motor shaft to be sure it is free of nicks and scratches.

1. Bolt the bracket down to the foundation (see Figure 8).
2. Slide the motor shaft through the seal and bolt up the motor (see
Figure 23). Make sure that the slinger is on the shaft between the
bracket and the motor flange. Make sure that you don’t chip the seal
face with the shaft shoulders and that the shaft does not take the weight
of the motor at any time.
3. CAREFULLY slide the rotating seal half onto the shaft, seal face first.
Make sure that you don’t chip the seal face on the shaft shoulders.
4. Follow the seal half with the spacer (Ref. No. 7). Slide the washer up
against the seal.
5. Slide a diffuser onto the shaft (open face out) until it seats on the
bracket (see Figure 9). Follow the diffuser with an impeller. Engage the
molded impeller key in the slot in the shaft. Don’t force it! Be sure that
the impeller eye, with metal ring, faces out (forward - see Figure 10).
6. Repeat step 4 with the remaining impellers and diffusers.
7. Reinstall the toothed washer, the flat washer, and the impeller nut (in
that order – Ref. Nos. 12,13,14) onto the motor shaft (see Figure 11).
Hold the shaft and tighten the impeller nut to 10 ft.-lbs. torque.
8. Check the sleeve O-Rings; if they show any damage or wear, replace
them. Reinstall the sleeve O-Rings (Ref. No. 8) on the bracket and the
suction body.
9. Reinstall the sleeve on the bracket and the pump suction body in the
sleeve. Be sure that you do not pinch or damage the O-Ring. See
Figure 27.
10. Install four cap screws (Ref. No. 18) through the pump head and into
the bracket. Tighten the cap screws to 22 ft.-lbs. torque.
11. Reinstall the drain plug and washer (Ref. Nos. 17 and 16) in the
suction body.
NOTICE: Do not disturb the recirculation valve.
12. Reinstall the suction and discharge piping and open all valves. Check
for leaks.
13. Prime the pump according to the instructions given in the
owner’s manual.
