With a flashlight, visually inspect the
oil in the housing to make sure it is
clean and clear, light amber in color
and free from suspended particles.
Milky white oil indicates the presence
of water. Oil level should be just
above the motor when pump is in
vertical position.
Oil Testing
Drain oil into a clean, dry
Ÿ
container by placing pump on it's
side, remove pipe plug, from
housing.
Check oil for contamination using
Ÿ
an oil tester with a range to 30
kilovolts breakdown.
If oil is found to be clean and
Ÿ
uncontaminated
above 15 kV breakdown), refill the
housing.
If oil is found to be dirty or

contaminated (or measures below
15 kV breakdown), the pump
must be carefully inspected for
leaks at the shaft seal, cable
assembly, square ring and pipe
plug, before refilling with oil. To
locate
the
leak,
pressure test.
After leak is repaired, dispose of old
oil properly, and refill with new oil.
Pressure builds up extremely
fast, increase pressure by
"TAPPING" air nozzle. Too
much pressure will damage
seal. DO NOT exceed 10 PSI.
Oil Replacement - Set unit upright
and refill with new cooling oil as per
table below. Fill to just above motor,
but below capacitor as an air space
must remain in the top of the
housing to compensate for oil
expansion.
Apply pipe thread compound to
threads of pipe plug then assemble
to housing.
DO
Overfilling of housing with oil
can create excessive and
dangerous hydraulic pressure
which can destroy the pump
and create a hazard.
Overfilling oil voids warranty.

3. Clean and examine impeller, for
cracks or breakage and replace if
required. To remove impeller, place a
flat screwdriver in the slot of the end
of the shaft to hold the shaft
stationary while unscrewing.
4. Check v-ring and remove if
damaged.
Power Cord and Motor:
5. Remove pipe plug and drain oil
from housing.

7. Remove screws and washers and
lift motor housing and stator from
seal plate.
8. Remove o-ring, replace if damaged.
9. Check motor capacitor with an
Ohm meter by first grounding the
capacitor by placing a screwdriver
across both terminals and then
removing screwdriver. Connect Ohm
meter (set on high scale) to terminals.
If needle moves to infinity (∞) then
drifts back, the capacitor is good. If
needle does not move or moves to
infinity (∞) and does not drift back,
replace capacitor.
10. Inspect motor winding for shorts
and check resistance values. Check
rotor for wear. If rotor or the stator
windings are defective, the complete
motor must be replaced.
Shaft Seal:
11. Remove snap ring from seal plate.
Remove shaft and motor rotor from
seal plate.
12. Remove seal's rotating member,
spring and retaining ring from seal
plate. Examine all seal parts, if seal
faces show signs of wear, uneven
wear pattern, chips or scratches

Bearings:
13. Examine lower bearing, and
upper bearing, if replacement is
required, remove by using a wheel
puller.
