• If oil is found to be clean and uncontaminated
(measuring 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, o-ring and pipe plug, before
refilling with oil. To locate the leak, perform the
following pressure tests.
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 P.S.I.
Motor Housing Pressure Test:
If oil has been drained, fill to normal level before
performing pressure test. Remove pipe plug from
motor housing.
Apply pipe sealant to pressure gauge assembly and
tighten into hole. Pressurize motor housing to 10 P.S.I.
Use soap solution around the sealed areas above the
oil level and inspect joints for “air bubbles”. For sealed
areas below oil level, leeks will seep oil. If, after five
minutes, the pressure is still holding constant, and no
“bubbles” /oil seepage is observed, slowly bleed the
pressure and remove the gauge assembly. Replace
oil. Leak must be located and repaired if pressure does
not hold.
Oil Replacement Motor Housing
Remove pipe plug from motor housing.
Drain all oil (if not already done so) from motor housing
and dispose of properly per Local Code. Set pump
upright and refill with new cooling oil, see “Cooling Oil”
chart. Fill to just above motor (1.2L) as an air space
must remain in the top of the motor housing to
compensate for oil expansion. Apply pipe thread
compound to threads of pipe plug then assemble to
motor housing. Check that o-ring is in place and does
not need to be replaced. Reassemble cord cap to
motor housing.
DO NOT overfill oil. 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.

WARNING:
Before any service work is done,
disconnect and lock out electrical power to
pump.
Volute
- Remove screws from volute.
Impeller
- Remove impeller by turning counter-
clockwise careful application of heat may be necessary.
Do Not store pump without impeller in place.
Seal
- Handle seal parts with care. Remove rotating
member from shaft. Remove pressed-in spring
component from seal plate. Examine all seal parts.
Inspect contact faces for signs of uneven wear tracks
on stationary face, chips and scratches on either seal
face. DO NOT interchange seal components, replace
the entire shaft seal if necessary.
Seal Plate
- Remove screws from seal plate. Remove
seal plate and o-ring.
Bearings
- Using a bearing puller or arbor press
remove bearing from shaft. Remove upper motor
bearing from shaft with a bearing puller.
IMPORTANT!- ALL PARTS MUST BE CLEAN
BEFORE REASSEMBLY. HANDLE SEAL
PARTS WITH EXTREME CARE. DO NOT DAMAGE
LAPPED SURFACES.
CAUTION:
Operating pump builds up heat and
pressure; allow time for pump to cool to room
temperature.
REASSEMBLY
Bearing -
Be careful not to damage the rotor shaft
when replacing bearing. Using an arbor press, hold the
rotor and press the upper bearing on the rotor shaft,
applying force to the inner race of the bearing only.
In the same manner replace lower bearing onto rotor
shaft.
