If oil is found to be dirty or

must be carefully inspected for

After leak is repaired, dispose of old

oil properly, and re ll with new oil.

Pressure Test (If oil has been

drained) - Remove pipe plug from

housing. Apply pipe sealant to

pressure gauge assembly and tighten

into hole. Pressurize motor housing

to 10 PSI. Use soap solution around

the sealed areas and inspect joints for

"air bubbles".

If, after ve minutes, the pressure is

"bubbles" are observed, slowly bleed

assembly. Replace oil. Leek must be

located and repaired if pressure does

not hold.

Pressure Test (If oil has NOT been

drained) - Oil should be at normal

level. Remove pipe plug (20) from

housing (4). Apply pipe sealant to

pressure gauge assembly and tighten

into hole. Pressurize motor housing

to 10 PSI. 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 ve minutes, the

and remove the gauge assembly.

Replace oil. Leek must be located and

Disassembly

Impeller, V-ring and Volute:

1. Disconnect power.

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.

remove

place a at 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

and disconnect the wires from the

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 rst 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 in nity (∞) then

drifts back, the capacitor is good. If

needle does not move or moves to

in nity (∞) and does not drift back,

replace capacitor.
