6. Check pump for proper
rotation before re turn ing to
normal service.
replacing Stator:
If motor winding is burned or
shorted, it can be rewound or
replaced with new factory wound
sta tor. Refer to sectional drawing
of pump and motor, and use the
following steps to remove and
replace stator.
1. If only the stator is damaged, it
may not be necessary to
com plete ly dismantle pump as
stator and housing can be lifted
from pump without dis turb ing
seals or bearings.
2. Drain all oil from upper housing.
Remove drain plug in bottom
of bearing housing, and
re move con nec tion box to
allow air to enter.
3. When connection box is
lifted off, con nec tion wires to
motor will be exposed. These
wires are tagged with a metal
marker giving wire num ber.
Disconnect wires and remove
connection box.
4. After chamber is drained,
remove hold-down bolts on
motor housing and lift off. Use
care in lifting as the seal failure
connecting wire must be
disconnected before hous ing
is completely re moved. See
sectional drawing.
5. The stator is held in the housing
with a bolted-in retaining ring
and pre vent ed from rotating by
a roll pin.
6. Remove the retaining ring and
socket head cap screw.

Maintenance
7. After ring is removed, turn
hous ing upright and bump on
hard wood block. This should
jar the stator loose and allow it
to drop out.
8. Thoroughly clean housing
before replacing new stator.
Replace sta tor and make all
wire con nec tions to con nec tion
box before re plac ing housing
on pump. See motor lead
connection drawing. This is
important as leads must be
tucked behind the windings
by using hands up through
rotor core.
iMPortANt: Use only butt
con nec tions on the wires.
Do not tape leads as oil will
de te ri o rate the tape and cause
dam age to stator and bearings.
9. Check top bearing. If the bearing
is clean and does not turn
rough, bearings can be reused.
If bear ings are damaged with
dirt or heat, they must be
replaced.
See addi tion al
instructions on replacing seals
and bearings.
10.Replace stator housing onto
seal chamber and bolt in place.
Be sure seal failure wires
are con nect ed before housing
is as sem bled.
Be sure O-ring seal has been
re placed. If O-ring is nicked or
cut, replace with new ring.
This ap plies to all O-rings
used in as sem bly.
11.After all leads are reconnected
in the con nec tion box (see
Figure 1, Page 11), make a
high voltage ground test on
each wire. The only wire that
should show ground is the
green power lead and the
ground head in the aux il ia ry
control cable.
12.For safety, complete pump
should be air checked under
water for leaks.
