MAINTENANCE & REPAIR PAGE E − 24
Do not operate the pump without the
guards in place over the rotating parts.
Exposed rotating parts can catch cloth-
ing, fingers, or tools, causing severe in-
jury to personnel.
Install the suction and discharge lines and open all
valves. Make certain that all piping connections are
tight, properly supported and secure.
Be sure the pump and engine have been properly
lubricated, see LUBRICATION.
Remove the fill cover assembly (28, Figure 4) and
fill the pump casing with clean liquid. Reinstall the
fill cover and tighten it. Refer to OPERATION, Sec-
tion C, before putting the pump back into service.
LUBRICATION
Seal Assembly
(Figure 5)
Before starting the pump, remove the vented plug
(11) and fill the seal cavity with approximately 132
ounces (3,9 liters) of SAE No. 30 non-detergent oil
to the middle of the sight gauge (15)
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 5)
The bearing housing was fully lubricated when
shipped from the factory. Check the oil level regu-
larly through the sight gauge (15A)
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 (13). 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 24
ounces (710 ml) 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
contact your local engine representative.
