LUBRICATION
(Figure 4)
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 5)
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.
