MAINTENANCE & REPAIR PAGE E - 10
hours of operation or once each month, whichever
comes first. Do not over lubricate. Over lubrication
can cause the bearings to over heat, resulting in
premature bearing failure.
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 1/3 lb. (0,15 kg.) of
grease.
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.
