Measure the total indicated runout (TIR) on the impeller wear rings, center sleeve, throttle sleeve,
diaphragm sleeve, 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.

1.
Fit the casing gasket (351) around all the hydraulics, bores, and through holes using the upper half
as a template.
Pay particular attention to the area around the seal chamber face. This is a critical area for proper
sealing. Make sure that the gasket extends all the way to the face but does not protrude past this
face. Use a file to make the face clean and flush.
2.
Assemble all casing studs (356A, 356C, 356K).
3.
Assemble the first-stage impeller casing ring* (164A), the final-series casing ring (164), the throttle
bushing (129), and both seal chambers (220, 221).
* 164A for 4x6-10D and 4x6-11BD pumps. 165B for all other pump sizes.
