fill cover and tighten it. Refer to OPERATION, Sec

LUBRICATION
Seal Assembly
(Figure 4)
Before starting the pump, remove the vented plug
(9) and fill the seal cavity with approximately 86
ounces (2,5 liter) of SAE No. 30 non‐detergent oil to
the middle of the sight gauge (25)
and maintain it at
the middle of the gauge. Clean and reinstall the
vented plug. Maintain the oil at this level.
NOTE
The white reflector in the sight gauge must be posi
tioned horizontally to provide proper drainage.
Bearings
(Figure 4)
The bearing housing was fully lubricated when
shipped from the factory. Check the oil level regu
larly through the sight gauge (26)
and maintain it at
the middle of the gauge. When lubrication is re
quired, add SAE No. 30 non‐detergent
oil through
the hole for the air vent (10). Do not over‐lubricate.
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 approximately 20
ounces (0,6 liter) clean oil. Change the oil more fre
quently if the pump is operated continuously or in
stalled 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
