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:
Crush hazard. The unit and the components can be heavy. Use proper lifting methods and wear steel-
toed shoes at all times.

CAUTION:

• Wear insulated gloves when you use a bearing heater. Bearings get hot and can cause physical

injury.

• 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.

• Check for magnetism on the pump shaft and degauss the shaft if there is any detectable

magnetism. Magnetism attracts ferritic objects to the impeller, seal, and bearings which
can result in excessive heat generation, sparks, and premature failure.
