F-3.4) Conduit Box and Cable Assembly:
Refi ll with cooling oil as outlined in paragraph F-1.3. Position
conduit box (10) and square ring (11) over opening, apply
thread locking compound to cap screws (6) threads and torque
to 16 ft lbs. Remove gland nuts (10B) and (10F), friction rings
(10C) and (10G), and grommets (10D) and (10H) from conduit
box (10) inspect and replace if required (see Fig. 4).
Insert one friction ring (10C), grommet (10D), one friction ring
(10C) and gland nut (10B) into conduit box for power cable
(10A). For control cable (10E), insert grommet (10H), friction
ring (10G) and gland nut (10F). Torque gland nuts (10B) and
(10F) to 15 ft. lbs to prevent water leakage.
F-4) Shaft Seal and Diaphragm Service:
CAUTION ! - handle seal parts with extreme care.
DO NOT scratch or mar lapped surfaces.
F-4.1) Disassembly and Inspection:
Diaphragm - To examine or replace the diaphragm (32) or shaft
seal (46), remove impeller (28) as outlined in paragraph F-2.1.
Drain oil from seal chamber as outlined in paragraph F-1.3.
Remove cap screws (8), washers (9) and lifting strap (7).
Set unit upside down on blocks to avoid damaging cords.
Remove socket head cap screws (39) and lift seal plate (25)
vertically, being cautious to avoid seal damage, together with
diaphragm (32), clamp (43) and outboard stationary member
(46A) of shaft seal (46), from bearing bracket (21). Examine
diaphragm (32), if it is ruptured, cracked or damaged, replace
by removing screws (44) and diaphragm clamp (43), Also,
clean out vent holes in seal plate (25). Check moisture sensor
probes (18) for damage. Replace by disconnecting wires (16)
by removing screws (14) and lockwashers (15). Then remove
probe (18) from bearing bracket (21).
Seal - To expose shaft seal (46) for examination, complete
above procedure and slide off outboard rotating member
(46B). See Fig. 5. Remove inboard rotating member (46), from
shaft. Examine all seal parts and especially contact faces.
Inspect seal for signs of wear such as uneven wear pattern on
stationary members, chips and scratches on either seal face.
DO NOT
interchange seal components, replace the entire
shaft seal (46).
F-4.2) Reassembly:
Diaphragm - At reassembly, make sure the bulge and molded-
in part number of diaphragm (32) is facing the seal plate (25).
With diaphragm (32) in place,lay diaphragm clamp (43) in
place on seal plate (25) and insert the four cap screws (44)
and tighten. Apply pipe thread compound to moisture sensor
probe (18), and insert in bearing bracket (21). Attach wires
(16) with lockwashers (15) and screws (14).
Seal- Clean and oil seal cavities in bearing bracket (21) and
seal plate (25). Lightly oil
(DO NOT use grease)
outer surface
of inboard stationary member (46E) and outboard stationary
member (46A). Press inboard stationary member (46E) fi rmly
into bearing bracket (21) and outboard stationary (46A) into
seal plate (25), using a seal pusher (see parts list- seal tool kit),
nothing but the seal pusher is to come in contact with seal face
(see Fig. 7).
IMPORTANT ! - DO NOT hammer on the seal
pusher- it will damage the seal face.
