MAINTENANCE & REPAIR

hours of operation or once each month, whichever
comes first. Do not over‐lubricate. Over‐lubrication
can cause the bearing to over‐heat, resulting in
premature bearing failure.

If grease is forced out around the shaft as
new grease is added, the bearing cavity is
full and should be disassembled and
cleaned immediately.

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 pedestal, fill the cavity
through the hole for the vented plug (10) with ap­
proximately 1/3 lb. (0.15 kg.) of grease (approxi­
mately 1/3 full).

For cold weather operation, consult the factory or a
lubricant supplier for the recommended grade of
lubricant.
