avoid damage. Remove impeller washer (199).
13. Mark the orientation of the gland half casing (100D) to
the column pipe (192). Disassemble the gland half casing
from the column pipe by removing capscrews (371W).
The gland liner (600T) will be attached to the casing.
14. Remove the gland liner (600T) from the gland half
casing (100D).
15. Mark orientation of column pipe (192) to bearing
frame (228). Disassemble column pipe from bearing
frame by removing capscrews (371M).
DISASSEMBLY OF POWER END
1. Remove the inboard bearing deflector (123A) by
sliding it down the shaft.
2. Remove the inboard seal plate (119B) with O-ring
(412) and seal (333) from the bearing housing (228).
3. Remove thrust housing locking capscrews (356B).
4. Draw thrust housing (134A) and shaft (122) from
bearing frame (228).
5. Check inboard bearing (168C) to see if it is worn,
loose, or rough and noisy when rotated. Press the
inboard bearing (168C) off the shaft (122) if
replacement is required. It is recommended that a new
bearing be installed after pressing off old bearing,
regardless of condition. The thrust bearing must be
removed from the shaft to replace the inboard bearing
(see step 7).
6. Remove the outboard deflector (123) by sliding up the
shaft.
7. Remove the thrust bearing locking clip (361) from the
thrust housing (134A).
8. Slide thrust housing (134A) up the shaft to remove
from the thrust bearing (112C).
7. Check outboard thrust bearing (112C) to see if they are
worn, loose, or rough and noisy when rotated. Remove
the outboard bearing locknut (136) and lockwasher
(382). Press the outboard bearing (112C) off the shaft
if replacement is required. It is recommended that a
new bearing be installed after pressing off old bearing,
regardless of condition.
8. Check the condition of the inboard seal (333). Remove
the inboard seal from the inboard seal plate (119B) if
replacement is required. It is recommended that a new
seal be installed after pressing out old seal, regardless
of condition.
9. Check the condition of the outboard seal (332). Press
the outboard seal from the thrust housing (134A) if
replacement is required. It is recommended that a new
seal be installed after pressing out old seal, regardless
of condition.
INSPECTIONS
IMPELLER
Replace if excessive erosion, extreme wear, or vane
breakage is evident. Reduction in hydraulic performance
may be caused by excessive wear, especially along the
suction wear ring surface.
SUCTION/GLAND LINERS
Replace if excessive erosion or extreme wear is evident.
CASING
Replace if excessive erosion, corrosion, or extreme wear is
evident.
SHAFT
Check for runout [0.006 in (.015 mm) maximum] to ensure
that the shaft is not bent. Bearing seats and seal areas must
be smooth and free of scratches and grooves. Shaft threads
must be in good condition. Replace if necessary.
COLUMN PIPE
Replace if worn or excessively corroded.
BEARINGS
Replace if worn, loose, or rough and noisy when rotated.
SEALS, O-RINGS, GASKETS
Replace during reassembly.
