IMPORTANT! - All parts must be clean before 
reassembly.

F-3.2) Reassembly:
Bearing - 

When replacing bearing, be careful not to damage 

the rotor or shaft threads. Clean the shaft thoroughly. Apply 
adhesive compound to the shaft and press bearing (47) on 
the motor shaft, position squarely onto the shaft applying 
force to the inner race of the bearing only, until bearing seats 
against the retaining ring (30). 

Moisture  Sensors  -

  If  pump  is  equipped  with  moisture 

sensors, reassemble by applying thread compound to threads 
on electrodes (18) and install in bearing bracket (21). Connect 
wire assemblies (16) to electrodes (18) with machine screws 
(14).

Thermal Sensors -

 If pump is equipped with Thermal Sensor, 

connect sensor leads to terminal block (55) as shown in Figure 
11.  If  sensor  is  not  functioning,  contact  factory  approved 
service center or contact factory service department.

Motor 

- Slide lower bearing (47) and motor shaft squarely 

into the bearing bracket (21) until bearing seats on the 
bottom. Install retaining ring (29) in bearing bracket (21). 
Place stator over rotor, lining up motor bolts with holes in 
bearing bracket (21). Position capacitor (3, 1 phase units) so 
that it will lay on the opposite side of the cord entry bosses 
of the motor housing (2). Reconnect capacitor leads. Torque 
motor tie bolts to 22 in-lbs. Set square ring (42) in groove on 
bearing bracket (21).

F-3.3) Wiring Connections:

Check power cord (52) and sensor cord (53), for cracks 
or damage and replace if required. Make internal wiring 
connections which are independent of the terminal block 
as shown in (Figure 12), using connectors (11) and wire 
assemblies (12) as required. Do not use wire nuts. Slip 
motor leads and ground wire through fi berglass sleeve (10). 
Lower motor housing (2) down onto bearing bracket (21) 
while aligning holes and stringing motor leads through the 
cable entry bore(s). (Slipping cords inside a 1 ft. length of .5” 

conduit makes this easier). Place socket head cap screws 
(51) into motor housing (2) and torque to 75 in-lbs. Install 
inner seal assembly as outlined in paragraph F-4.2. Install 
square ring (42), bearing bracket (21), square ring (42) in 
position on pump. Place socket head cap screws (39) into 
seal plate (25) and torque to 75 in-lbs. 

Reconnect motor and sensor leads to the underside of the 
terminal block(s) (56), (55) as shown in Figure 5 & 11. Note 
that the pins are numbered underneath the terminal block. 
Place o-ring (57) into groove in terminal block and lubricate 
with dielectric oil. Press the terminal blocks (55) (56) into the 
housing so it seats completely below the snap ring groove. 
Place snap ring (54) 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/Sensor Cord - 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 cable plug into housing 
bore aligning timing mark with hole in terminal block (55) 
(56) (see Figure 6). Compress cord plug with compression 

fl ange (52a)(53a) by tightening cap screws (6) into the motor 
housing (2). Torque to 132 in-lbs.
