Reassembly

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.
• Make sure that all parts and threads are clean and that you have followed all directions
under the Preassembly inspections section.
•
detectable magnetism. Magnetism attracts ferritic objects to the impeller, seal, and
bearings which can result in excessive heat generation, sparks, and premature failure.
