IMPORTANT !
T 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 (6), washer
(7), bearing (8) and seal parts (9b, c, d) into lower end bell
(22) until bearing (8) seats in lower end bell (22). Center
washer (7) on bearing (8) and tighten conduit bushing (6)
on lower end bell (22).
Lower motor stator over rotor until seated in lower end bell
(22), while aligning holes for motor bolts. Insert motor bolts
and torque to 17 inch pounds. If pump is a single phase
unit place bracket (31) on one of the motor bolts. Insert
capacitor (32) in bracket (31), attach motor leads with flag
terminals to capacitor and place terminal boot (33) over
terminals.
Set motor housing (3) next to motor (5) and lower end bell
(22) assembly. Make wire connections per paragraph
F-3.3. Set square ring (24) in groove on lower end bell (22)
and lower motor housing (3) down onto lower end bell (22)
while aligning holes. Place socket head cap screws (23)
through lower end bell (22) into motor housing (3) and
torque to 60 inch pounds. Assemble impeller and volute
per paragraph F-2.2.
F-3.3) Wiring Connections:
Check power cable (28) and control cable (39) (if used),
for cracks or damage and replace if required (see Figure
7). Place parts (28b, c & d) on power cable (28a), and parts
(39b, c & d) on control cable (39a if equipped). Bring cord
sets (28) and (39 if equipped) through openings in top of
motor housing (3) and reconnect motor leads to power
cable (28) and temperature sensor leads to control cable
(39 if equipped) using connectors (4), and in addition use
(34) and (35) for three phase units and temperature sensor
leads, as shown in Figure 8. Attach ground wire to motor
with screw (27).
F-3.4) Cable Assembly:
Power Cable-
Make wire connections as outlined in
paragraph F-3.3. Refill with cooling oil (if it has been
drained) as outlined in paragraph F-1.3. Insert one friction
ring (28c), grommet (28d), another friction ring (28c) into
motor housing (3). Apply pipe sealant to gland nut (28b)
and screw into motor housing (3). Torque gland nut (28b)
to 15 ft. lbs. to prevent water leakage (see Figure 7).
Control Cable (Optional)-
Insert one friction ring (39c),
grommet (39d) and another friction ring (39c) into motor
housing (3). Apply pipe sealant to gland nut (39b) and
screw into motor housing (3). Torque gland nut (39b) to 15
ft. lbs. to prevent water leakage (see Figure 7).
