Pump Is Lound: Pac Fab 1.5 Challenger Pump

I have a Challenger CH11-N1-1 1/2 FE3P (Part Number34-5386)

It has gotten really loud. It doesnt sound like the screaming from the bearing failures.  Should I replace the motor? The motor is A.O. Smith part number  SQ1102.

What is the right replacement motor.

Thanks

Yes, we would recommend replacing the motor. The Challenger model number signifies a 1.5HP full rated 3-phase motor. Your current motor is a 1HP full rated single phase motor. If you need another single-phase motor, we’d recommend model number B2842.
