Be 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. With lapped surface facing
bearing housing (16), slide rotating
member onto shaft using seal pusher
tool, until lapped faces are together.
It is extremely important to keep seal
faces clean during assembly. Dirt
particales lodged between faces will
cause the seal to leak.
Be sure driving lugs in retainer are
matched in rotating member of seal
(19). Place spring over shaft and in
place on rotating member, making
sure it is seated in retainer and not
cocked or resting on bellows tail.
Lightly oil shaft and inner surface of
outboard rotating member.
Spring should be properly engaged
in both retainers.
Reassemble the diaphragm (21) with
"bulg" facing diaphragm plate (22).
Place plate (22) on diaphragm (21)
and insert capscrews (23) into plate
and tighten.
Place diaphragm plate (22) over shaft
onto bearing housing (16), being
careful not to damage outboard
stationary member and align holes
for cap screws (25).
Conduit Box Assembly -
Check
power (35) and control cables (36) for
crackes or damage and replace
complete conduit box (4) if required.
(See Figure 4) Bring motor wires
through opening in top of motor
housing (3), check sleeving and
replace if damaged. Position square
ring (5) in conduit box (4) and
reconnect leads using connectors
and insulators. See Figures 5, for
wiring schematics.
Refill with cooling oil. Position
conduit box (4) with square ring (5)
on motor housing. Apply thread
locking compound to cap screws (6)
threads and torque to 16 ft/lbs.
IMPORTANT! - Hammering
on the seal pusher tool will
damage the seal face.

Service
With tail section toward bearing
housing (16), slide rotating member
onto shaft with seal pusher tool until
retainer engages spring and spring is
compressed slightly.
Thread cap screws (25) into bearing
housing (16) and tighten. Refill
chamber with oil.
Remove gland nuts (35B) and (36B),
friction rings (35C) and (36C), and
grommets (35D) and (36D) from
conduit box (4), inspect and replace if
damaged (See Figure 4). Reassemble
by inserting one friction ring,
grommet, one more friction ring and
gland nut into conduit box. Torque
gland nuts to 15 ft/lbs to prevent
leakage.
