4. Set assembly on bench and
remove connection box. When
box is lifted off, connection
wires to motor will be
exposed. These wires will
probably be burned, but each
wire is tagged with a metal
marker giving wire number.
Cut the wires.
If the leads to the connection
box are burned, a complete
new connection box with new
wire must be used. The wires
are potted in with sealing
compound and a new unit must
be obtained from the factory.
5. The stator is held in the housing
with a bolted-in end ring and
an outside locking screw to
prevent stator from turning.
6. After ring is removed, turn
housing upright and bump on
hardwood blocks. This should
jar the stator loose and allow it
to drop out.
7. Thoroughly clean housing
before replacing new stator.
Replace stator and make all
wire connections to connection
box before replacing housing
on pump. This is important as
leads must be tucked behind
the windings by using hands
up through rotor core.
IMPORTANT: Use only
compression type insulated
connectors on the wires.
DO NOT TAPE LEADS AS
OIL WILL DETERIORATE
THE TAPE AND CAUSE
DAMAGE TO STATOR AND
BEARINGS.
8. Drain oil from chamber. If
oil is clean and no water is
present, seals can be considered
satisfactory to reuse.
9. Check top bearing. If clean and
does not turn rough, bearings
can be reused and it is not
necessary to completely
dismantle pump to change
bearings. If bearings are
damaged with dirt or heat, they
must be replaced. See additional
instructions on replacing seals
and bearings. Remember to
reinstall the upper bearing
load spring.
10.Before replacing stator housing,
be sure outside lock screw is in
place and that O-ring is used
under head of bolt. A leak here
can cause a motor failure. If a
new stator has been used, it
will be necessary to drill into
the stator lamination for a
holding socket for bolt (

deep into the stator). This
holding spot is drilled through
the bolt hole when the stator
is bolted in place with the
end ring.
11.Replace stator housing onto
seal chamber and bolt in place.
BE SURE SEAL FAILURE
WIRE IS CONNECTED
BEFORE HOUSING IS
ASSEMBLED.
Be sure back-off screws have
been loosened so that parts
can come metal to metal. Be
sure O-ring seal has been
replaced. If O-ring is nicked or
cut, replace with new ring.
This applies to all O-rings used
in assembly.
12.After all leads are reconnected
in the connection box, make a
high voltage ground test on
each wire. The only wire that
should show ground is the
green power lead and the
ground lead in the auxiliary
control cable.
13.For safety, complete pump
should be air checked under
water for leaks. If seals were
OK, refill seal chamber with
oil. Lay pump on side for this
oil filling with oil fill hole
