LUBRICATION
Seal Assembly
(Figure 4)
Fill the seal cavity through the hole for the vented
plug (11) with SAE No. 30 non-detergent oil to the
line on the sight gauge (25). Check the oil level reg-
ularly and refill as required. When lubricating a dry
seal cavity, add approximately approximately 112
U.S. ounces (3,3 liters) of oil to level indicated.
NOTE
The white reflector in the sight gauge must be posi-
tioned horizontally to provide proper drainage.
Bearings
(Figure 4)
The bearing housing was fully lubricated when
shipped from the factory. Check the oil level regu-
larly through the sight gauge (25A)
and maintain it
at the midpoint of the gauge. When lubrication is
required, remove the air vent (13) and add SAE No.
30 non-detergent oil through the opening. When
lubricating a dry (overhauled) bearing housing, fill
the bearing cavity with approximately 18 ounces
(532 ml) of oil. Clean and reinstall the air vent. Do
not over-lubricate. Over-lubrication can cause the
bearings to over-heat, resulting in premature bear-
ing failure.
NOTE
The white reflector in the sight gauges must be po-
sitioned horizontally to provide proper drainage.
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.
Engine
Consult the literature supplied with the engine, or
contact your local power unit representative.
