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.
