vented plug. Check the oil level regularly through
the sight gauge (23)
and maintain it at the midpoint
of the gauge.
Bearings
(Figure 5)
The bearing housing was fully lubricated when
shipped from the factory. Check the oil level regu
larly through the sight gauge (27, Figure 4)
and
maintain it at the midpoint of the gauge. When lu
brication is required, remove the air vent (6) and
add SAE No. 30 non‐detergent oil through the
opening. When lubricating a dry (overhauled) in
termediate, fill the bearing cavity with approximate
ly 40 ounces (1,2 liter) of oil. Clean and reinstall the
air vent.
Do not
over‐lubricate. Over‐lubrication
can cause the bearings to over‐heat, resulting in
premature bearing failure.
Under normal conditions, drain the bearing hous
ing once each year and refill with clean oil. Change
the oil more frequently if the pump is operated con
tinuously or installed in an environment with rapid
temperature change.
Monitor the condition of the bearing lubri
cant regularly for evidence of rust or mois
ture condensation. This is especially im
portant in areas where variable hot and
cold temperatures are common.
For cold weather operation, consult the factory or a
lubricant supplier for the recommended grade of
oil.
