Inspect strainer (24) and clean, making sure holes are not
clogged to ensure unrestricted flow. Now position strainer (24)
onto suction case (4) and inserting screws (40) with washers
(65) in holes and tightening.
F-4) Shaft Seal Service:
F-4.1) Disassembly:
To replace outer shaft seal, drain oil per Section F-2.1 and
remove impeller per Section F-3. Remove the shim washers
(17a) & (17b), impeller key (15), seal retaining ring (48a) seal
spring (48b), and seal rotating member (48c) from shaft, See
Figure 8.
Examine all seal parts and specifically contact faces. Inspect
seal for signs of uneven wear pattern on stationary members,
chips and scratches on either seal face.
DO NOT
interchange
seal components, replace the entire shaft seal (48). If replacing
seal, remove screws (14) from seal retainer (12) and carefully
pry the retainer (12) from diffuser (9) being careful not to damage
diffuser (9) or o-ring (13), now remove retainer from the shaft.
This will allow the removal of stationary (48d) by pushing out
from back side of retainer or prying out with flat screw driver.
To remove inner shaft seal (10), remove snap ring (11), spring
retainer (10a), and spring (10b) from shaft. The diffuser (9) and
the rest of the inner seal (10) can now be removed by tapping
the diffuser with a plastic hammer until free. Pull the lower end
assembly from the stator/frame assembly, and check the rotor
and stator for evidence of water, oil, electrical or mechanical
damage. If damaged, replace rotor and stator/frame assembly,
See section F-6.
F-4.2) Reassembly:
Inner Seal -
Clean oil cavity in diffuser (9). Lightly oil
(DO
NOT use grease)
outer surface of stationary member (10d).
Press stationary member (10d) firmly into diffuser (9), using a
seal pusher (see Parts List - seal tool kit). Nothing but the seal
pusher is to come in contact with the seal face. Make sure the
stationary member is in straight. (See Figure 9A).
CAUTION ! - Handle seal parts with extreme care.
DO NOT scratch or mar lapped surfaces.
IMPORTANT ! - DO NOT hammer on the seal
pusher- it will damage the seal face.
Slide a bullet (see parts list-seal tool kit) over motor shaft.
Lightly oil
(DO NOT use grease)
shaft, bullet and inner
surface of bellows on rotating member (10c). With lapped
surface of rotating member (10c) facing inward toward
stationary member (10d), slide rotating member (10c) over
bullet and onto shaft, using seal pusher, until lapped faces of
(10d) and (10c) are together (see Figure 9B).
