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 6). 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 7),
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 plate (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 22 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.
Place all motor leads above motor. Position square 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 75 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 cord (10), for cracks or damage and replace if
required (see Figure 11). Make internal wiring connections
which are independent of the terminal block as shown in
(Figure 10), using connectors (11) and wire assemblies (17) as
required. Do not use wire nuts. Slip motor leads and ground
wire through fi berglass sleeve. Lower motor housing (2) down
onto seal plate (24) while aligning holes and stringing motor
leads through the cord entry bore. (Slipping cordsinside a 1 ft.
length of .5” conduit makes this easier). Place socket head cap
screws (35) through seal plate (24) into motor housing (2) and
torque to 75 in-lbs.
Reconnect motor leads to the underside of the terminal block
(15) as shown in Figure 10. Note that the pins are numbered
underneath the terminal block. Place o-ring (9) into groove in
terminal block (15) and lubricate with dielectric oil. Press the
terminal block (15) into the housing so it seats completely below
the snap ring groove. Place snap ring (8) into groove in cord
entry bore of motor housing (2).
