connecting wire must be
disconnected before housing
is completely removed. See
sectional drawing.
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 clamp
ring.
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.Replace stator housing onto
seal chamber and bolt in place.
Be sure seal failure wire is
connected before housing is
assembled.
Be sure O-ring seal has been
replaced. If O-ring is nicked
or cut, replace with new rings.
This applies to all O-rings used
in assembly.
11.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.
12.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
upright. Do not completely fill;
leave oil about 1 inch below
plug hole. Use only high grade
transformer oil or regular
Hydromatic submersible oil in
this chamber. Replace plug;
use Permatex on threads.
Install air valve in top plug
opening of motor housing and
charge housing with about
10 psi of air. Be sure air is dry.
Do not use air line where water
