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 square key.
6. Remove the retaining ring and
socket head cap screw.
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
ad di tion al instructions on
re plac ing 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, 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.
Install air valve in 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
may be trapped in the line.
Submerge com plete unit un der
water and check for leaks.
If seals were okay, refill seal
cham ber with oil. Lay pump
on side for this oil filling with
oil fill hole upright. Do not
completely fill; leave oil about
1" below plug hole. Use only
Hydromatic sub mers ible oil or
high grade trans form er oil in
this chamber. Re place plug;
use Permatex on threads.
13.Refill motor chamber with oil
through con nec tion box
opening. Use high grade, non-
syn thet ic trans form er oil or
Hydromatic spe cial submersible
oil. Fill hous ing until oil covers
top of wind ings. Leave air
space in top for expansion.
NOTE: Oil must cover top
of stator.
replacing Seals and Bearings:
1. Drain all oil from motor chamber
and seal chamber as described.
2. Remove motor housing as
de scribed in re plac ing stator.
3. Remove bolts that hold bearing
housing to volute. Lift bearing
housing and rotating unit off
and set assembly on its side.
Remove socket head screw and
washer at the impeller end of
the shaft. Hold ing the shaft
stationary, re move the impeller
from the shaft by tap ping the
end of the impeller blades.
4. To remove seal plate take out
sock et head screws and using
screws in back-off holes, pry
plate loose. This will also force
seal off if not already removed.
5. Remove snap ring. Pull seal
if it is free. If not free, it
can be forced off when shaft
is re moved. The labyrinth ring
must also be removed.
6. Set seal housing in upright
po si tion and bump end of shaft
on hard wood block. This will
push the bearing from the
hous ing and will force upper
seal from shaft.
7. Use bearing puller to remove
bear ings. Replace with new
bear ings. Press only on
inner face of bearing when
replacing. Pressing on outer
face can damage the bear ing.
Bearings are stan dard size
that can be obtained from
any bearing sup ply house
or can be obtained from
Hydromatic factory.
8. iMPOrTANT: Do not use
any of the old seal parts.
Replace with all new seals
.
NOTE: Any time seal is
disturbed, replace seal.
9. Thoroughly clean all castings
be fore re plac ing seals. One
grain of dirt between the seal
faces can cause failure.
NOTE: The labyrinth ring must
be installed with the groove
facing OPE.
