Maintenance
6. Remove the old O-ring (24), regardless of condition,
and replace. Place the new O-ring over the seal plate
shoulder. Do not 'roll" it. If twisted, water may enter
chamber and cause failure.
7. Clean the motor housing (2) thoroughly, then
position it onto the seal plate.
8. Press the rotating seal half (20) onto the shaft with
the rubber ring facing the impeller.
NOTICE Mixing old and new seal parts will cause
immediate seal failure. When replacing seal, replace
both the rotational and the stationary seal halves.
9. Reassemble the lower seal as described.
10. To check seal probe, if equipped, use an ohmmeter
to measure resistance and check continuity. If meter
reads zero then replace probe (23). Check probe
sensor wire (22) for opens using the ohmmeter.
If reading is zero the wire is OK. For shorts place
lead on the motor housing, making sure bare metal
surface is used. Place the other lead on the bared
end (26) of the probe lead (22). Reading should
be infinity (∞). If reading is zero then replace seal
probe lead.

11. Add a drop of Locktite® 243 to the impeller
threads and screw the impeller (16) on hand tight.
The impeller will force the rotating seal half (20)
into position.

12. Set the seal housing and motor housing assembly
into the volute case (10) and secure with screws (7).
13. To replace the power cord on 1ø pumps, first slip the
stator lead wires through the holes in the wire seal
assembly. Coat the cord grip threads with PTFE pipe
thread sealant tape and screw the new power cord
assembly into the motor housing. Referring to wiring
diagrams in this manual, secure wires together with
wire nuts.
NOTICE Do not tape leads together as the hot oil
will deteriorate the tape and cause failure.
14. Before filling the motor housing with oil, a seal leak
test should be performed. Apply 7 to 8 pounds of
air pressure in the 1⁄4" NPT tap (9) on the top of the
motor housing.
NOTICE Too much pressure will damage the seal.
Seal would have to be replaced.
Then submerge the pump in water and check for
leaks. If a leak occurs, isolate where it is coming
from and correct the problem by replacing the
sealing part.

Oil fill

1. After seal leak test is satisfactory, remove unit from
water and wipe or blow off any excess water.
2. Do not put oil in motor with any water present in
motor cavity.
3. Use refined paraffinic transformer oil,
2210 or equivalent.

4. Slowly fill oil to 1/8" over windings in motor housing
through opening (9). Use an oil fill tube that will go
into holes so that air can escape. Replace plug (9).
NOTICE Do not fill the motor housing completely –
allow air space for expansion.
5. Connect power cord wires to terminals in panel, or
connect power source, and check pump running.
Motor should run smoothly and be free of vibration.
Pump is ready for operation.
