T-Motor Voltage Change 
This procedure will provide you with step by step instructions 
to convert the operating voltage of dual voltage motors. 
1. Remove cap screws holding motor to 
volute 
2. Slowly, and carefully lift motor straight 
up (Do not allow rotor to scrub against 
stator!) Lift motor part way and 
disconnect seal probe. Failure to 
disconnect will cause the probe to 
become damaged and rip out (Fig.1) 
3. Remove wavy washer from upper 
bearing and set it aside. 
4. Turn motor over and gently untuck 
wire bundles from around the stator 
winding. (Fig. 2) 
5. Record the wires in each of the 
bundles. If there are 4 bundles, the 
pump is wired for 230V. If there are 6 
bundles, the pump is wired for 460V. 
6. Identify and separate the bundle that 
has wire number 1. Also separate any 
bundles that have numbers 4, 5, and 
6. (Fig. 3)

7. Re-connect the wires as seen in  
(Fig. 4). 
8. Separate the wire bundle with wire 
number 2 and re-connect as seen in 
(Fig 4). 
9. Separate the wire bundle with wire 
number 3 and re-connect as seen in 
(Fig 4). 
10. Double-check all wires have been 
connected correctly. 
11. Gently tuck wire bundles behind stator 
windings, being certain nothing 
extends below the motor housing. 
(Fig. 5) 
12. Place wavy washer back on top of 
upper bearing and verify large motor 
housing o-ring is positioned in its 
groove. 
13. Slowly and carefully lower motor 
housing onto pump (DO NOT ALLOW 
ROTOR TO SCRUB AGAINST 
STATOR.) For T-motors, re-connect 
seal probe.
14. Re-attach motor housing to volute with 
cap screws.
15. Record voltage change in pump  
service manual.
16. Pump is now ready to operate.
