chamber assembly on the hopper spool (31, Fig
ure 3). 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
Before starting the pump, remove the vented plug
(5) and fill the seal cavity with approximately 8
quarts (7,6 liters) of SAE No. 30 non‐detergent oil
or to the center of the sight gauge (30 Figure 4).
Clean and reinstall the vented plug. Maintain the oil
level at the middle of the sight gauge.
Bearings
(Figure 5)
The bearing housing was fully lubricated when
shipped from the factory. Check the oil level regu
larly through the sight gauge (23)
and maintain it at
the midpoint of the gauge. When lubrication is re
quired, remove the air vent (6) and add SAE No. 30
non‐detergent oil through the opening. When lubri
cating a dry (overhauled) intermediate, fill the bear
ing cavity with approximately 40 ounces (1,2 liter).
Clean and reinstall the air vent. Do not over‐lubri
cate. Over‐lubrication can cause the bearings to
over‐heat, resulting 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.
