19. Remove the impeller (101) and O-ring (412A)
(Figure 23).
20. Using a scribe, put a small mark on each of
the column pipes, steady bearings, adapter,
and motor support to match mark the pieces.
This will help in identifying and aligning during
re-assembly.
21. Loosen the bolts (370G) that hold the adapter
(108A) to the column pipe. Slide the adapter
from the shaft (122). If adapter is difficult to
remove, shaft end may be corroded. Remove
any rough spots or corrosion using an emery
cloth (Figure 24).
22. If your pump has no intermediate steady
bearings (only one column section), you will
not have any column extension (306) or
steady bearing housing (213). Go to step 24.
23. Starting at the casing end of the pump (Figure
25), remove column to steady bearing housing
bolts (372B) and remove column extensions
(306), steady bearing housings (213), and
deflectors (123) one at a time. While removing
column sections, support the shaft to prevent
bending. There is usually no need to remove
the head column (192) (Figure 26). Do not
remove steady bearings at this time. Refer to
the inspection procedures prior to removal.
