Seal - To expose shaft seal (12) for examination, complete
above procedure and slide off outboard rotating member
(12B), See Figure 4. Remove inboard rotating member (12D),
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 (12).
F-4.2) Reassembly:
Diaphragm -
At reassembly, make sure the bulge and mold-
ed-in part number of diaphragm (14) is facing the seal plate
(13). With diaphragm (14) in place, lay diaphragm clamp (15)
in place on seal plate (13) and insert the four cap screws (16)
and tighten. Apply pipe thread compound (40) to moisture
sensor probe (29), and insert in bearing bracket (4). Attach
wires (31) with lockwashers (34) and screws (33).
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 Figures 5 & 6).
Important ! - DO NOT hammer on the seal pusher-
it will damage the seal face.
Make sure the stationary members are in straight and that
the rubber ring is not out of it’s groove. Lightly oil
(DO NOT
use grease) shaft and inner surface of bellows on rotating
member (12D) See Figure 7. With lapped surface facing
bearing bracket (4), slide rotating member (12D) onto shaft,
using seal pusher, until lapped faces of (12D) and (12E) are
together (See Figure 6). It is extremely important to keep seal
faces clean during assembly. Dirt particles lodged between
these faces will cause the seal to leak.
Make sure driving lugs in retainer are matched in rotating
member. Place spring (12C) over shaft and in place on rotating
member (12E), making sure it is seated in retainer and not
cocked or resting on bellows tail. Re-oil shaft and lightly oil
inner surface of outboard rotating member (12B). With tail sec-
tion toward bearing bracket (4), slide rotating member (12B)
onto shaft with seal pusher until retainer engages spring (12C)
and spring is compressed slightly. Make sure spring (12C) is
properly engaged in both retainers. Slide seal plate (13) over
shaft onto bearing bracket (4), being careful not to damage
outboard stationary member (12A) and align holes for socket
head cap screws (17). Thread socket head cap screws (17)
into bearing bracket (4) and tighten. Fill seal chamber with
oil as outlined in paragraph F-1.3. Reassemble impeller and
volute per paragraph F-2.2.
F-4.3) Wiring Connections:
Check power cable (49A) and control cable (49D), on conduit
box (49), for cracks or damage and replace complete conduit
box assembly (49) if required (See Fig. 9). Bring motor wires
through wire opening in top of housing (1),check sleeving (36)
and replace if required, position square ring (21) in conduit
housing (49) and reconnect motor leads to power cable and
moisture and temperature sensor leads to control cable using
connectors (22), (32) and insulators (36) as show in Figure 8.
