MAINTENANCE & REPAIR PAGE E − 35
Final Pump Assembly
(Figure 3)
Secure the suction spool bracket (16, Figure 6) to
the base with the previously removed hardware.
Reinstall the air intake cover assembly (42) and se-
cure it with the previously removed hardware.
LUBRICATION
(Figure 10)
Seal Assembly
Before starting the pump, remove the vented plug
(12) and fill the seal cavity with approximately 4
quarts (3,8 liters) of SAE No. 30 non-detergent oil
to the center of the sight gauge (15A). Clean and
reinstall the vented plug. Maintain the oil level at the
middle of the sight gauge.
NOTE
The white reflector in the sight gauge must be posi-
tioned horizontally to provide proper drainage.
Bearings
(Figure 12)
The bearing housing was fully lubricated when
shipped from the factory. Check the oil level regu-
larly through the sight gauge (15)
and maintain it at
the midpoint of the gauge. When lubrication is re-
quired, remove the air vent and bushing (13 and
14) and add SAE No. 30 non-detergent oil through
the opening. When lubricating a dry (overhauled)
intermediate, fill the bearing cavity with approxi-
mately 10 ounces (0,3 liter) to the midpoint of the
sight gauge. 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.
