Crane Barnes 3SE3024L, Installation And Operation Manual

11

Place all motor leads above motor. Position square ring (42) 
on seal plate (25) and lower motor housing (2) over motor 
and into pilot. Place socket head cap screws (39) through 
seal plate (25) 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 cords (10) for cracks or damage and replace 
if required. Make internal wiring connections which are 
independent of the terminal block as shown in (Figure 10), 
using connectors (23) and wire assemblies (29) as required. 
Do not use wire nuts. Slip motor leads and ground wire 

through fi berglass sleeve (22). Lower motor housing (2) 
down onto seal plate (25) while aligning holes and stringing 
motor leads through the cord entry bore(s).  (Slipping cords 
inside a 1 ft. length of .5” conduit makes this easier). Place 
socket head cap screws (39) through seal plate (25) into 
motor housing (2) and torque to 75 in-lbs. 

Reconnect motor leads to the underside of the terminal 
block(s) (27) as shown in Figure 8. Note that the pins are 
numbered underneath the terminal block. Place o-ring (12) 
into groove in terminal block (27) and lubricate with dielectric 
oil. Press the terminal block (27) 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). Repeat 
terminal block installation for sensor cord, if equipped.

F-3.4) Cord Assemblies:
Power -

 Refi ll the cooling oil as outlined in paragraph F-1.4. 

Make wire connections as outlined in paragraph F-3.3. 
Insert female end of cord plug into housing bore aligning 
timing mark with hole in terminal block (27) (see Figure 

5). Compress cord plug with compression fl ange (10a) 
by tightening cap screws (24) into the motor housing (2). 
Torque to 132 in-lbs.
