When looking at a frame size you cannot change from the "J". This letter referres to the method the pump housing will bolt onto the motor. The numbers 56 refer to the physical size of the pump, specifically the distance the center of the shaft would sit off of the surface on which it rests. You can sometimes go from a 56 frame to a 48 frame but you will need to add a spacer given the smaller physical size. Some pump bases will have a stilt that can be switched around or removed to accomodate different motor barrel sizes.

if the pump is higher than the pool, you should have a ball valve at the front of the pump. close this valve, fill pump housing with water. close the system, open the valve and turn on pump. if the pump is below the pool level, you shouldnt have this problem.

These motors are "brushless". If the motor has failed it usually is because of a failure in the windings. If it it making a loud noise, that is the bearings going out.

1 or 2 speed? what is your power supply voltage? Make sure your motor is the same voltage as your supply voltage. if all is 120 vac - one hot wire on L1 (normally black) one common wire on C or N (normally white) and the ground wire onto ground lug (normally green)

It doesn't matter. Both sides are "hot".

This really sounds like a motor going out. I would take it to a motor shop and have them check the bearings. US Parts Center

sounds like something is caught in impeller while apart you might find impeller is bad

need more info where is this handle located

We need the make and model of the pump (ex. Hayward Super ll, Pentair WhisperFlow), and where the leak is. Your motor will fit a lot of different pumps. Thanks.

go top the pentaire website and see if they can assist..

the pump end should be repairable without taking the motor apart ..normally the long bolts that run through the motor housing can be taken out and the pump end serviced without pulling it all apart..send a photo of the pump..

Sounds like a capacitor replacement is needed normally the motor gives a growling sound. The second possibility is the switch to disengage the starting winding is frozen and will not open when the motor rotation starts going.

split the pump and clean the impeller. might have trash in it and this will impede flow, it's a big help to know what brand and model pump when asking.
