6.6.1 Assemble the power end
This procedure explains how to assemble a standard ring-oil or optional purge-oil mist-lubricated power
end and includes information for the assembly of these optional features:
•
Pure-oil mist-lubricated power end
•
Radial-heat-flinger
•
Air-cooling package
•
Water-cooling package
WARNING:
Lifting and handling heavy equipment poses a crush hazard. Use caution during lifting and
handling and wear appropriate Personal Protective Equipment (PPE, such as steel-toed shoes,
gloves, etc.) at all times. Seek assistance if necessary.
CAUTION:
•
Risk of physical injury from hot bearings. Wear insulated gloves when using a bearing
heater.
•
This pump uses duplex bearings mounted back-to-back. Make sure orientation of the
bearings is correct.
NOTICE:
•
There are several methods you can use to install bearings. The recommended method is
to use an induction heater that heats and demagnetizes the bearings.
