perform a pressure test.
After leak is repaired, dispose of old
oil properly, and refill with new oil.

2.
Remove
lockwashers, vertically lift motor
housing and seal plate assembly from
volute. Clean out volute if necessary.
3. Inspect gasket and replace if cut or
damaged.
4. Clean and examine impeller, for
cracks or breakage and replace if
required.
To
remove
place a flat screwdriver in the slot of
the end of the shaft to hold the shaft
stationary while unscrewing the
impeller.
5. Check v-ring and remove if
damaged.
Power Cord and Motor:
6. Remove pipe plug and drain oil
from housing.
7. Remove gland nut, washer and
ring from housing. Pull cord through

terminals on power cord.
8. Remove screws and lift motor

housing and stator from seal plate.
9. Remove v-ring, replace if damaged.
10. 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.
