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)
