NOTICE:
Make sure the threads are clean. Deburr if necessary. Apply an anti-seize compound to the
threads.
3.
Install the impeller wear ring (142).
See Replace the wear rings in the Preassembly inspections section.
4.
Install the casing and head wear rings (164).
See Replace the wear rings in the Preassembly inspections section.
5.
Install the throat bushings (125).
See Replace the throat bushings in the Preassembly inspections section.
NOTICE:
The impeller and wear-ring clearance setting procedures must be followed. Improperly set-
ting the clearance or not following any of the proper procedures can result in sparks, unexpect-
ed heat generation, and equipment damage.
6.
Measure the TIR on the impeller wear rings, impeller locknuts, and bearing fits.
The shaft is the datum point. Measure the runout of wear rings and impeller nuts to the shaft with a
dial indicator.
API limits are listed in the Shaft and rotor runout requirements table.

6.6.2 Install the rotating element assembly
1.
Use straps and a crane to insert the rotating element into the casing. Use precaution to not scuff the
impeller (101), impeller nuts (124) and (130), or throat bushing surface.
a) Insert the rotating element enough to support the radial end of the shaft in the throat bushing
bore of the casing (100). This will prevent the pump from slipping and causing possible human
injury.
b) Reposition the straps and slide the rotating element the remainder of the way into the casing
(100).
