Rated 4 out of 5 by from Warning wired for 220v Even though the box started it was a 120v replacement motor, it was wired for 220v. I notice a slow start and no power. Immediately turned it off. Was able to rewire with diagrams of side of motor.

Motor says its CW rotation. Is the rotation direction viewed from the output shaft end or the connection end (what I would call the rear) of the motor? Hoping the CW rotation is viewed from the rear.

Asked by: Westwood
It would be viewed from the rear.

Can this motor be powered with a generator?

Asked by: jperry01
According to factory the 9040 is not to be run with a generator. The motor will run on a generator But will shorten the life of the motor a lot. It will blow out the start & run capacitors. This also voids warranty.
