Bearings
The pedestal was fully lubricated when shipped
from the factory. Check the oil level regularly
through the sight gauge (28)
and maintain it at the
middle of the gauge. When lubrication is required,
add SAE No. 30 non‐detergent
oil through the hole
for the air vent (16). Do not over‐lubricate. Over‐lu­
brication can cause the bearings to over‐heat, re­
sulting 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 for
the recommended grade of oil.
