MAINTENANCE & REPAIR PAGE E − 10
There are no provisions in the bearing cavity to
drain or flush the lubricant. The pump and pedestal
must be disassembled to completely clean and
maintain this cavity.
Under normal conditions, change the grease after
each 5000 hours of operation, or at 12 month inter-
vals, whichever comes first. Change the grease
more frequently if the pump is operated continu-
ously or installed in an environment where variable
hot and cold temperatures are common.
When lubricating a dry (overhauled) pedestal, fill
the cavity with approximately 1.5 ounces (43
grams) of grease.
For cold weather operation, consult the factory or a
lubricant supplier for the recommended grade of
lubricant.
Seal Assembly
The seal assembly is lubricated by the medium be-
ing pumped. No additional lubrication is required.
Power Source
Consult the literature supplied with the power
source, or contact your local power source repre-
sentative.
