! WARNING
Do not remove completely at this point. Failure to
follow these instructions could result in property
damage, severe personal injury, or death.
8. Separate the upper and lower halves by use of a pry bar
between the two halves or by the use of jacking screws if
the top half is provided with tapped holes.
9. When halves separate, slide upper half away from
lower half, maintain a downward pressure on the
stabilizing rod end furthest from the pump and slowly
remove completely the remaining upper most bolt.
Allow the top half to slide on alignment rods.
10. Balancing the upper half with the stabilizing rod, lower the
top half to the ground allowing the upper half to rotate so
that its main joint flange sets on the ground (See Fig. 36).
11. Rotating element is now ready for inspection or
removal. If element is inspected and does not need to
be removed, then refer to upper half reassembly
procedures.
ROTATING ELEMENT REMOVAL
12. For these procedures it will be necessary to remove the
line shafting or motor, then remove the pump half
coupling.
13. Thread a long bolt, washer and nut through the hole at
the end of the shaft. (See Fig. 37)
14. Sling around eye bolt, putting slight amount of tension
on sling.
15. Remove the four bolts (372U) from each bearing
housing that are holding the bearing housing to the
casing.
16. Lightly tapping on inboard and outboard bearing
housings to spread them apart, slide rotating element
away from lower half.
17. Lower rotating element to ground by sliding outboard
bearing housing away from pedestal enabling element
to be set on floor with shaft in
a horizontal position. (See Fig. 38)
18. Rotating element can now be serviced following
disassembly procedure given previously in this
manual.
REASSEMBLY OF ROTATING
ELEMENT
19. Inspect main joint gasket and replace if necessary.
(Follow replacement instructions in disassembly
procedures section.)
20. Sling around the bolt in end of pump shaft.
21. On full pedestals, the lifting sling must come through hole
in top plate of pedestal (See Fig. 38).
22. When rotating element is off the ground and in the
vertical position, align any anti-rotation pins in the
casing rings and stuffing boxes for proper orientation
in the slots in the casing lower half.
23. Assemble rotating element in lower half casing (100).
Correctly locate casing ring pins (445A) in casing
main joint.
NOTE: Sliding inboard bearing housing toward
coupling prior to assembling rotating element in
casing will ease assembly.
