If replacement is required, remove seal parts, rotating
member (5b), spring (5c) and retaining ring (5d) from shaft.
Examine all seal parts and especially contact faces. Inspect
seal for signs of wear such as uneven wear pattern on
stationary members, chips and scratches on either seal face.
DO NOT interchange seal components, replace the entire
shaft seal (5). If replacing seal, remove stationary (5a) from
intermediate coupling (6) by prying out with flat screwdriver.
Now bearing (3) can be removed from motor shaft by
removing retaining rings (2) from shaft and then by using a
wheel puller or arbor press. Check sleeve bearing (48) for
excessive wear, if replacement is required, press sleeve
bearing (48) from intermediate support (6).
Inspect motor windings for shorts and check resistance
values. Check rotor for wear. If rotor or stator windings are
defective the complete motor must be replaced.
If OPTIONAL moisture sensors are damaged, remove
machine screws (44) from probes (42) and then remove
probes (42) from intermediate coupling (6).
IMPORTANT !
ALL PARTS MUST BE CLEAN BEFORE
REASSEMBLY.
D-4.2) Reassembly:
Moisture Sensors -
If pump is equipped with optional
moisture sensors, to reassemble, apply thread compound to
threads on probes (42) and install in intermediate coupling
(6). Connect wires (39) to probes (42) with machine screws
(44). Note, if pump is not equipped with moisture sensors,
item (42) probes will be replaced by pipe plugs (36).
Bearings - When replacing bearings, be careful not to
damage the rotor or shaft threads. Clean the shaft
thoroughly. Apply adhesive compound to shaft and press
bearing (3) on, applying force to the inner race of bearing
only. Install retaining rings (2) on shaft, making sure bearing
(3) is positioned between the retaining rings. Apply adhesive
to shaft and press top bearing (9) on, applying force to the
inner race of bearing only. If the intermediate coupling’s
bearing is worn or damaged, the complete intermediate
coupling assembly must be replaced.
CAUTION !
HANDLE SEAL PARTS WITH EXTREME CARE. DO
NOT SCRATCH OR MAR LAPPED SURFACES.
Inner Seal - Clean and oil seal cavities in intermediate
coupling (6). Lightly oil ( DO NOT use grease) outer surface
of stationary member (5a). Press stationary member (5a)
firmly into intermediate coupling (6), using a seal pusher.
Nothing but the seal pusher is to come in contact with seal
face (see Fig. 6). Make sure the stationary member is in
straight. Place retaining ring (5d) and spring (5c) over shaft
until seated on shaft shoulder. Slide a bullet over motor shaft
threads. Lightly oil ( DO NOT use grease) shaft, bullet and
inner surface of bellows on rotating member (5b). See Figure
7. With finished end away from motor, slide rotating member
(5b) over bullet and onto shaft until it engages spring (5c).
Make sure spring is seated on retainer and not cocked or
resting on bellows tail.
Motor - Slide motor rotor, bearings (3) & (9) and inner seal
(5) into intermediate coupling (6). Insert retaining ring (7) into
intermediate coupling (6). Set motor stator over rotor being
sure that stator drops flat against register in intermediate
coupling (6). Place end bell on to motor and Insert motor bolts
in motor and torque to 17 inch pounds.
2HP Pumps - Set square-ring (8) in groove on intermediate
coupling (6), place hex nut (49) on cable (15) and run cables
(15) and (16) through motor housing (10). Lower motor
housing (10) down onto intermediate coupling (6) and make
wire connections per paragraph D-4.3. Once wire
connections are made place motor housing (10) onto
intermediate (6), be sure square-ring (8) is in the groove on
intermediate coupling (6). Insert cap screws (12) with
washers (11) through motor housing (10) into intermediate
coupling (6) and tighten.
3,5,7.5HP Pumps - Set square-ring (8) in groove on
intermediate coupling (6) and lower motor housing (10) down
onto intermediate coupling (6). Place lockwashers (11) on
cap screws (12) and insert through motor housing (10) into
intermediate coupling (6) and tighten. Place square ring (14)
on motor housing (10). Set cover plate (13) with cables (15)
and (16) next to motor housing assembly and make wire
connections per paragraph D-4.3. Once wire connections are
made place cover plate (13) on motor housing (10) and insert
cap screws (18) with washers (11) into motor housing (10)
and tighten. Place lifting bail (40) into position on cover plate
(13) and insert cap screws (46) with lockwashers (11) on and
tighten.
Assemble cable assemblies per paragraph D-4.4. Assemble
outer seal per paragraph D-3.2 and impeller, cutters and
volute per paragraph D-2.2. Refill with cooling oil per
paragraph D-1.3.
D-4.3) Wiring Connections:
Check power cable (15) and control cable (16) for cracks or
damage and replace if required. When replacing control
cable (16) check to see if it is a two wire cable (temperature
sensor only-Std) or a five wire cable (moisture & temperature
sensors). Place parts (15b, c & d) on cable (15a) and parts
(16b, c & d) on cable (16a). Bring cord sets (15) and (16)
through opening in top of motor housing (10) on 2HP pumps
or cover plate (13) on 3,5,7.5HP pumps, and reconnect motor
leads to power cable (15) using connectors (17) and control
cable (16) to temperature sensor leads and to wires (39)
(optional for moisture sensors) with connectors (43). See
Figure 8. Connectors (41) are used on 460 volt motor to tie
wires T4 & T7, T5 & T8 and T6 & T9 together and connector
(47) ties wires T4, T5 and T6 together on 200-230 volt 3
phase motors. Replace ground screw (37) into motor on 2HP
pumps or cover plate (13) on 3,5,7.5HP pumps.
