MAINTENANCE & REPAIR PAGE E - 10
Do not fill the bearing cavity through the vent plug
in the top of the housing. This will result in over‐fill­
ing, and can cause leakage, excessive heat build­
up and/or premature bearing failure.
Check the oil level regularly through the constant
level oiler and add oil as required.
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.
