5.10 Bearing lubrication
WARNING:
Risk of explosive hazard and premature failure from sparks and heat generation. Ensure bear-
ings are properly lubricated prior to startup.
NOTICE:
Grease can settle in equipment left idle leaving bearings improperly lubricated. Check the
greasing on a pump that has been out of service for a long period of time and re-grease if nec-
essary.
Pumps are shipped without oil. You must lubricate oil-lubricated bearings at the job site.
Grease-lubricated bearings are lubricated at the factory.
5.10.1 Lubricate the bearings with oil
WARNING:
Risk of explosive hazard and premature failure from sparks and heat generation.
Ensure bearings are properly lubricated prior to startup.
1.
Remove the oil fill pipe plug (319B).
2.
Fill the bearing frame with oil through the filler connection that is located on the top of the bearing
frame.
3.
Fill the bearing frame with oil until the oil level reaches the middle of the sight glass or opposite
sight glass (319 or 408N). The correct volume of oil required for each size of bearing frame can be
found in the ‘Oil Volume Requirements’ section in the ‘Bearing Maintenance’ / ‘Maintenance’ portion
of the IOM.
