Lost high speed on 56J frame motor and found a 56y frame. Will 56y frame work on a 56J frame setup?
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.

the pump must not have any air leaks in the suction side of it,, or it will just **** air and not water,,, water is very heavy you see, however i think its the impeller in the pump thats the problem,,,you should try to put water in the out let of the pump so you fill the pump with water first if its dryed out it may just wear out the impeller before it starts to **** water up, if this still dont work turn off the stop **** and strip out the pump to look at the impeller any wear on it and it will need a new one fitted
i hope this has help you, good luck
