Bearing - Examine bearing (39) and replace if required. If re-
placement is required, remove bearing (39) from motor shaft us-
ing a wheel puller. Washer (28), retaining ring (29) and conduit
bushing (30) can now be removed from motor shaft.
IMPORTANT ! - All parts must be clean before
reassembly.
F-3.2) Reassembly:
Bearing - When replacing bearing, be careful not to damage
the rotor or shaft threads. Clean the shaft thoroughly. Slide
conduit bushing (30) and washer (28) over motor shaft. Insert
retaining ring (29) into groove on shaft. Apply adhesive com-
pound to the shaft and press bearing (39) on the motor shaft,
position squarely onto shaft applying force to the inner race of
the bearing only, until bearing seats against retaining ring (29).
Seal - Clean and oil seal cavity in seal plate (24). Press sta-
tionary member (38a) fi rmly into seal plate (24), using a seal
pusher, nothing but the seal pusher is to come in contact with
seal face (See Figure 4). Make sure the stationary member is in
straight.

IMPORTANT ! - DO NOT hammer on the seal
pusher- it will damage the seal face.
Slide retaining ring (38d) over shaft and let rest on bearing
(39). Place spring (38c) over shaft and let rest on retaining ring
(38d). Lightly oil ( DO NOT use grease) shaft, bullet and inner
surface of bellows on rotating member (38b), (See Figure 5),
with lapped surface of rotating member (38b) facing outward,
slide over bullet and onto shaft using seal pusher, making sure
spring (38c) is seated in retaining ring (38d) and spring (38c) is
lined up on rotating member (38b) and not cocked or resting on
bellows tail.

Motor - Slide motor rotor with conduit bushing (30), washer
(28), bearing (39) and seal parts (38b, c, d) into seal plate (24)
until bearing (39) seats in seal platel (24). Center washer (28)
on bearing (39) and tighten conduit bushing (30) on seal plate
(24). Lower motor stator over rotor until seated in seal plate
(24), while aligning holes for motor bolts. Insert motor bolts and
torque to 17 inch pounds. If pump is a single phase unit place
bracket (14) on one of the motor bolts. Insert capacitor (3) in
bracket (14), attach motor leads with terminals to capacitor and
place terminal boot (26) over terminals.
Place all motor leads above motor. Position o-ring (36) on seal
plate (24) and lower motor housing (2) over motor and into pilot.
Place socket head cap screws (35) through seal plate (24) into
motor housing (2) and torque to 60 inch pounds. Make wire
connections per paragraph F-3.3. Assemble impeller and volute
per paragraph F-2.2.
F-3.3) Wiring Connections:
Check power cable (15A) and control cable (15E - if used), on
cord grip plate (9) or conduit box (15), for cracks or damage
and replace if required (See Figure 6 or 7). Bring motor wires
through wire opening in top of housing (2), position square ring
(10) in cord grip plate (9) or conduit housing (15) and reconnect
motor leads to power cable and temperature sensor leads to
control cable (if equipped) using connectors (11) and (53) as
Seal Pusher
show in Figure 8.

IMPORTANT ! - it is extremely important to keep
seal faces clean during assembly. Dirt particles
lodged between these faces will cause the seal to
leak.
