LUBRICATION
(Figure 6)
Seal Assembly
Fill the seal cavity through the hole for the vented
plug (14) with SAE No. 30 non-detergent oil. Check
the oil level regularly and refill as required. When lu-
bricating a dry seal cavity, add approximately
approximately 256 oz. or 8 U.S. quarts (7,6 liters) of
oil to level indicated.
Bearings
(Figure 7)
The bearing housing was fully lubricated when
shipped from the factory. Check the oil level regu-
larly through the sight gauges (5)
and maintain it at
the midpoint of the gauge. When lubrication is re-
quired, remove the air vent and bushing (9 and 10)
and add SAE No. 30 non-detergent oil through the
opening. When lubricating a dry (overhauled)
bearing housing, fill the bearing cavity with approx-
imately 40 ounces (1,2 liters) of oil. Clean and rein-
stall the air vent. Do not over-lubricate. Over-lubri-
cation can cause the bearings to over-heat, result-
ing in premature bearing failure.
NOTE
The white reflector in the sight gauge must be posi-
tioned 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 engine representative.
