17. Spread opening of remaining coupling guard half
(501B) slightly and place over installed coupling guard
half so that annular groove in remaining coupling
guard half faces the driver (Fig. I-B-9).
18. Repeat steps 14-16 for rear end of coupling guard half
(501B), except that nut should be finger tightened only.
19. Adjust length of coupling guard to completely cover
shafts and coupling as shown in Fig. I-B-10 by sliding
rear coupling guard half (501B) towards motor.
20. Repeat steps 14-16 for center slots in coupling guards.
21. Tighten all nuts on the guard assembly firmly.
DISASSEMBLY
The coupling guard must be removed for certain
maintenance and adjustments to the pump, such as
adjustment of the coupling. The coupling guard should be
replaced after maintenance is completed.
s
! WARNING
Before assembly or disassembly of the coupling guard
is performed, the driver must be de-energized, the
driver controller / starter put in a locked-out position
and a caution tag placed at the controller / starter
indicating the disconnect. Replace coupling guard
before resuming normal operation of the pump. ITT
Industries - Goulds Pumps assumes no liability for
avoiding this practice.
s
! WARNING
DO NOT resume normal pump operation with the
coupling guard removed.
1. Remove nut, bolt and washers from center slotted hole
in the coupling guard assembly.
2. Slide driver end coupling guard half (501B) towards
pump (Fig. I-B-10).
3. Remove nut, bolt and washers from driver coupling
guard half (501B).
4. Spread opening of driver coupling guard half (501B)
slightly and lift over remaining coupling guard half
(Fig. I-B-9).
5. Remove nut, bolt and washers from remaining
coupling guard half (501B).
6. Spread bottom of coupling guard half slightly and lift
off pump end plate (234B) (Fig. I-B-5).
This completes disassembly of the coupling guard.
NOTE: It is not necessary to remove the thrust
deflector fan guard from the pump bearing frame.
Before removing other components, refer to
