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 drain/fill plug (83) in the
motor housing. Tip the pump and drain off a small
amount of oil into a transparent cup. If the oil level is
abnormally low, or the color milky or dark, refer to
Draining Oil From Seal Cavity in this section for
instructions and troubleshooting tips.
To fill the seal cavity, remove the seal cavity drain/fill
plug (83) and add 7 ounces (0,2 liter) of SAE No. 10
non‐detergent oil. Refer to Section B, Installation,
for positioning of the pump during filling of the seal
cavity. Apply `Loctite Pipe Sealant With Teflon No.
592.' or equivalent to the threads of the pipe plug,
before reinstalling the plug.
Motor Cavity
The motor cavity is cooled by the liquid being
pumped. No further lubrication is required.
