Seal - Clean and oil seal cavity in lower end bell (10). Press
stationary member (1a) fi rmly into lower end bell (10), using
a seal pusher (see parts list - seal tool kit), 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 (1d) over shaft and let rest on bearing
(21). Place spring (1c) over shaft and let rest on retaining
ring (1d). Lightly oil
(DO NOT use grease) shaft, bullet
and inner surface of bellows on rotating member (1b), (see
Figure 7), with lapped surface of rotating member (1b)
facing outward, slide over bullet and onto shaft using seal
pusher, making sure spring (1c) is seated in retaining ring
(1d) and spring (1c) is lined up on rotating member (1b) and
not cocked or resting on bellows tail.
IMPORTANT ! - It is extremely important to keep
seal faces clean during assembly. Dirt particles
lodged between these faces will cause the seal
to leak.
Motor - Slide motor rotor with conduit bushing (16), washers
(25), (33) bearing (21) and seal parts (1b, c, d) into lower
end bell (10) until bearing (21) seats in lower end bell (10).
Center washers (25), (33) on bearing (21) and tighten
conduit bushing (16) on lower end bell (10).
Lower motor stator over rotor until seated in lower end bell
(10), while aligning holes for motor bolts. Insert motor bolts
and torque to 17 inch pounds. If pump is a single phase unit
place bracket (17) on one of the motor bolts.
Insert capacitor (18) in bracket (17), attach motor leads with
fl ag terminals to capacitor and place terminal boot (15) over
terminals.
Set motor housing (11) next to motor (14) and lower end
bell (10) assembly. Make wire connections per paragraph
F-3.3. Set square ring (23) in groove on lower end bell (10)
and lower motor housing (11) down onto lower end bell (10)
while aligning holes. Place socket head cap screws (36)
through lower end bell (10) into motor housing (11) and
torque to 60 inch pounds. Assemble impeller and volute per
paragraph F-2.2.
F-3.3) Wiring Connections:
Check power cord (12), for cracks or damage and replace
if required (see Figure 8). Place parts (12b, c & d) on power
cord (12a). Bring cord sets (12) through openings in top of
motor housing (11) and reconnect motor leads to power cord
(12) using connectors (19), as shown in Figure 9. Attach
ground wire to motor with screw (20).
F-3.4) Cord Assembly:
Power Cord
- Make wire connections as outlined in
paragraph F-3.3. Refi ll with cooling oil (if it has been
drained) as outlined in paragraph F-1.3. Insert one friction
ring (12c), grommet (12d), another friction ring (12c) into
motor housing (11). Apply pipe sealant to gland nut (12b)
and screw into motor housing (11). Torque gland nut (12b) to
15 ft. lbs. to prevent water leakage (see Figure 8).
