DIAL INDICATOR METHOD (CV 3196)
1. Remove coupling guard. Refer to coupling guard
instructions
Appendix II.
2. Remove coupling.
3. Set indicator so that button contacts either the
shaft end or against the face of coupling (Fig. 38).
4. Loosen each locking bolt (370C) several turns.
5. Loosen jam nuts (423) on jack bolts (370D) and
turn bolts in several turns until impeller contacts
the stuffing box cover or seal chamber. Turn
shaft to ensure contact is made.
6. Set dial indicator at zero.
7. Back off the jacking bolts (370D) several turns
and tighten the locking bolts (370C) to move the
impeller away from the stuffing box cover or seal
chamber until the dial indicator shows that a .060"
clearance has been obtained.
8. Turn in the jacking bolts (370D) and tighten the
jam nuts (423) evenly.
9. Check shaft for free turning.
10. Replace coupling.
11. Replace coupling guard.
FEELER GAUGE METHOD (all but CV)
1. Remove coupling guard. Refer to coupling guard
instructions in
Appendix II.
2. Loosen jam nuts (423) on jack bolts (371A) and
back bolts out about two turns (Fig. 39).
3. Tighten locking bolts (370C) evenly, drawing
bearing housing (134A) towards frame (228) until
impeller contacts the casing. Turn shaft to ensure
contact is made.
4. Using a feeler gauge, set the gap between the
three locking bolts (370C) and bearing housing
(134A) per impeller clearances in
Table 3.
5. Evenly back out bearing housing (134A) using the
three jack bolts (370D) until it contacts the locking
bolts (370C). Evenly tighten jam nuts (423B).
6. Check shaft for free turning.
7. Replace coupling guard.
FEELER GAUGE METHOD (CV)
1. Remove coupling guard. Refer to coupling guard
instruction in
Appendix II.
2. Remove coupling.
3. Loosen each locking bolt (370C) several turns.
4. Loosen jam nuts (423) on jack bolts and turn bolts
in several turns until impeller contacts the stuffing
box cover or seal chamber. Turn shaft to ensure
contact is made.
5. Measure the gap between the bearing housing and
the bearing frame with feeler gauges. Reduce this
measurement by .060" and place the resultant
feeler gauges between the bearing housing and
the bearing frame as shown in Fig. 39.
6. Back off the jacking bolts (370D) several turns
and tighten the locking bolts (370C) to move the
impeller away from the stuffing box cover or seal
chamber until the bearing housing snugs up the
feeler gauges between the bearing housing and
the bearing frame.
7. Turn in the jacking bolts (370D) and tighten the
jam nuts (423) evenly.
8. Check shaft for free turning.
9. Replace coupling.
10. Replace coupling guard.
