seal cavity can cause hot oil to be
ejected as the plug is removed.
To check the seal cavity oil, lay the pump on its side
and remove the seal cavity plug (13) in the interme
diate. Tip the pump and drain off a small amount of
oil into a transparent cup. If the oil level is abnor
mally low, or the color milky or dark, refer to
Drain
ing Oil From Seal Cavity
in this section for instruc
tions and troubleshooting tips. If the oil is clear, ap
ply `Loctite Pipe Sealant With Teflon No. 592' or
equivalent to the threads of the pipe plug, before
reinstalling the plug.
To fill the seal cavity, remove the pipe plug (15) and
add the recommended grade of submersible
pump oil. Apply `Loctite Pipe Sealant With Teflon
No. 592' or equivalent to the threads of the pipe
plug, before reinstalling the plug.
See Table E-2 for quantity of lubricant when lubri
cating a dry (overhauled) pump. See Table E-3 for
lubricant specifications.
The grade of lubricant used is critical to the opera
tion of this pump. Use premium quality hydraulic oil
as specified in the following table. Oil must be
stored in a clean, tightly closed container in a rea
sonably dry environment.

Motor Housing Cavity
With the pump in an upright position, remove the
pipe cap (27) on the top of the pump and the oil lev
el plug (21) in the side of the pump. See Table E-2
and add the recommended grade of lubricant
(Table E-3) to the motor cavity until the oil begins
to drain from the oil level plug opening. Apply `Loc
tite Pipe Sealant With Teflon No. 592' or equivalent
sealant to the threads of the oil level plug and pipe
cap and reinstall the plug and pipe cap.
Maintain
the oil at this level
.
Never attempt to fill the motor cavity
through the drain plug (16) opening or the
oil level plug (21). A volume of air must be
trapped above the motor to permit thermal
expansion of the motor oil.
