To fill the seal cavity, remove the pipe plug (11) and
add the recommended grade of submersible

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

Motor Housing Cavity
With the pump in an upright position, remove the
pipe cap (27) on the top of the pump. See Table
E-2 and add the recommended quantity of lubri­
cant to the motor cavity. Maintain the oil at this
level. Apply `Loctite Pipe Sealant With Teflon No.
592' or equivalent sealant to the threads of the
street tee assembly (28). Reinstall and tighten the
cap.
Never attempt to fill the motor cavity
through the drain plug (10) opening. A vol­
ume of air must be trapped above the mo­
tor to permit thermal expansion of the mo­
tor oil.
