chamber assembly on the hopper spool (not
shown). Secure the priming chamber assembly
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 5)
Seal Assembly
Fill the seal cavity through the hole for the vented
plug (5) 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 (25 and 28)
and
maintain it at the midpoint of the gauge. When lu-
brication is required, remove the air vent (6) 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.
