Older Hayward Super pump humming not starting

[exit]

I have an older Super Pump(model C48K2N143B1) that hums on start up but won't pump and turns off from heat shortly after. Here's the troubleshooting I've done so far:

1. Checked for debris, turbine spins freely
2. Checked for obvious damage, none
3. Replaced start capacitor... twice. 2nd one made sure to test with multimeter to verify functionality.
4. Checked shaft, spins freely

Same symptoms/problem.

Anything I'm forgetting? Handy but not an expert on electrical motors.

Does that model also have a run capacitor?

I don't see an obvious one. There's no bump/hump; just the capacitor in the cap at the end w/ the other connections/heat switch

Can you show a picture of the motor label and the wires in the back of the motor?

Check the centrifugal switch on the back of the motor. Sounds like it is trying to start on the high windings.

Thanks... seems to move freely, didn't pull it apart. Gave up and bought a replacement. When I have freetime I'll noodle with old motor and maybe repurpose it.
