Maintenance (Continued)
10. Hold motor shaft with 7/16” open
end wrench on shaft flats and screw
impeller onto shaft. Be sure you do
not touch capacitor terminals with
body or any metal object.
Tightening impeller will auto-
matically locate seal in correct
position.
11. Remount diffuser on seal plate. BE
SURE diffuser is right side up as
follows (Figure 20).
a. Rib next to priming hold should
be at six o’clock position;
b. Part number (N1-28P) should be
between nine o’clock and ten
o’clock;
c. Both mounting screws must
engage screw holes in seal plate
(Figure 20).
d. BE SURE rubber pad (See Figure
20) stays in place on top of
diffuser.
12. Follow instructions under “Pump
Reassembly,” at right.
IMPORTANT:
If the copper heat sink
moves or shifts during seal removal, it
should be removed and reinstalled.
NOTE:
First, follow instructions under
“Pump Disassembly”.
Remove ceramic portion of sink (See
“Removing Old Seal”). Grasp copper
cone with fingers at the large end and
move back and forth. Be careful not to
deform it.
COPPER HEAT SINK INSTALLATION
1. Clean off all sealant and foreign
material.
2. Clean out heat sink cavity in seal
plate.
3. Apply thin layer of non-hardening
Permatex on outer surface of heat
sink (part that fits into cavity, Figure
21).
4. Using standard 7/8” socket, bolt, and
1
3

” washer pull heat sink into cavity
(See Figure 22).
5. Clean out any surplus Permatex from
insert cavity where new seal will be
located (Figure 23).
6. Follow steps 2 through 11 under
“Installing New Seal”.
PUMP REASSEMBLY
1. Install new O-Ring gasket on seal
plate (Figure 29, Ref. Nos. 5 and 3).
2. Pick up a small amount of liquid soap
on one finger and spread evenly over
O-Ring gasket for lubrication during
reassembly. Be careful not to nick or
tear O-Ring.
3. Replace motor onto pump body; be
sure rubber pad stays in place on top
of diffuser. Tighten four hex nuts
and lockwashers snugly (35-45 inch-
lbs. torque). Do not overtighten.
