Bearings
(Figure E‐2)
The bearing housing was fully lubricated when
shipped from the factory. Check the oil level regu­
larly through the sight gauge (30)
and maintain it at
the middle of the gauge. When lubrication is re­
quired, remove the air vent and bushing (11 and
12) and add SAE No. 30 non‐detergent
oil through
the hole until the level is at the middle of the sight
gauge. Do not over‐lubricate. Over‐lubrication can
cause the bearings to over‐heat, resulting in pre­
mature 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 27
ounces (0,8 liter) of clean oil. Change the oil more
frequently if the pump is operated continuously 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.
