Goulds Pumps 3171 - IOM - Manual (Page 44)

Disassemble the column
1. Remove the column down to the steady bearing housing bolts (372B).
If your pump has no intermediate steady bearings (only one column section), then skip this step since
you do not have any column extension (306) or steady bearing housing (213).
a) Start at the casing end of the pump and remove the column extensions (306), steady bearing
housings (213), and deflectors (123) one at a time. Support the shaft in order to prevent bending
while you remove these sections.
It is not necessary to remove the head column (192). Do not remove the steady bearings at this
time. Refer to inspection procedures prior to removal.
