Installation Guide

MAINTENANCE
Clean strainer basket regularly. Do not strike
basket to clean. Inspect strainer cover gasket
regularly and replace as necessary.
Hayward pumps have self-lubricating motor bearings
and shaft seals. No lubrication is necessary.
Keep motor clean. Insure air vents are free from
obstruction.
Occasionally, shaft seals become damaged or
worn and must be replaced. See instructions.
REMOVING THE MOTOR ASSEMBLY
Remove the four (4) 3/8” x 2” hex head bolts
which hold the motor assembly to the pump/
strainer housing.
Slide the motor assembly out of the pump/strainer
housing, exposing the diffuser. Pull the diffuser off
of the seal plate, exposing the impeller. (The diffuser
may remain in the pump/strainer housing. To
remove, pull it straight out of the strainer housing.)
REMOVING THE IMPELLER
Remove the motor end cover by removing the two
(2) screws.*
For A.O.S. motor, hold motor shaft from turning.
Carefully slide a 7/16” wrench between the
capacitor and the protector switch, and rotate the
impeller so the wrench fits over the 2 flats on the
motor shaft. For magnetic motor, snap capacitor
out of bracket and use 3/8” open end wrench on
motor shaft flats.
Rotate the impeller counterclockwise and remove.
The spring portion of the seal assembly is now
exposed. Note carefully the position of the spring
seal, and remove it.
NOTE: Replace motor cover to protect delicate
motor parts.
REMOVING THE CERAMIC SEAT
Remove the seal plate. Note the notch on the top
of the plate and the mating lug on the top of the
motor mounting bracket.
Press the ceramic seat with O-ring out of the seal
plate. If tight, use a small screwdriver to tap seat
out.
STOP—Clean all recesses and parts to be reassembled.
Inspect gaskets and replace if necessary.
STORAGE/WINTERIZING
Drain pump by removing drain plug(s) and store in
strainer basket.
Disconnect electrical wires and pipe connections,
and store pump in dry, well-ventilated room. Or, as
a minimum precaution:
Disconnect electrical wires. Remove four bolts
holding bracket and motor assembly to strainer
housing and store assembly in a dry, well-ventilated
room. Protect remaining strainer housing
assembly from the elements by covering.
NOTE: Before reactivating pump, thoroughly clean and remove scale, dirt, etc.
SEAL INSTALLATION
Clean and lubricate the impeller hub shaft and
pump housing seal recess with a dilute solution of
non-granulated, liquid-type soap. The use of
petroleum or silicone lubricants may contribute to
seal leakage.
Gently wipe the black, polished surface of the
spring seal assembly with a clean, soft cotton
cloth. Press the spring seal assembly onto the
impeller hub—black polished surface facing away
from the impeller.
Gently wipe the polished face of the ceramic seat
with a soft, cotton cloth. Lubricate the O-ring on
the ceramic seat and press it firmly and evenly
into the recess of the seal plate—polished side
facing out.
Place the seal plate onto the motor mounting
bracket aligning the positioning lug and guide.
REPLACING THE IMPELLER AND DIFFUSER
Screw the impeller onto the motor shaft in a
clockwise direction. Tighten snugly by holding
motor shaft with wrench.
Place the diffuser over the impeller onto the seal
plate, fitting positioning lug between the two
guides.
REPLACING THE MOTOR ASSEMBLY
Slide the motor assembly, with the diffuser in
place, into pump/strainer housing, being careful
not to dislodge the diffuser.
Fasten assembly to housing using the four (4)
3/8” x 2” bolts. (Be sure housing gasket is in
place.) Tighten alternately and evenly.
