chamber assembly on the hopper spool (not

with the hardware (6 and 7).
Reconnect the suction piping to the hopper spool
and the air discharge tubing to the priming cham
ber assembly.
LUBRICATION
(Figure 4)
Seal Assembly
Remove the pipe plug (10) and fill the seal cavity
through the hole with SAE No. 30 non‐detergent
oil. Check the oil level regularly and refill as re
quired. When lubricating a dry seal cavity, add
approximately approximately 256 oz. or 8 U.S.
quarts (7,6 liters) of oil to the center of the sight
gauge (8). Clean and reinstall the pipe plug.
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 gauges. When lubrication is re
quired, remove the air vent (10) and add SAE No.
30 non‐detergent oil through the opening. When
lubricating a dry (overhauled) bearing housing, fill
the bearing cavity with approximately 40 ounces
(1,2 liters) 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 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.
