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.

SOURCE: Hayward Self-Priming Pump with AO Smith 1 HP 56J

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

Wiring line side of 230v two speed pool pump. It has line 1-4 which do I use


There should be a schematic on that motor describing how to connect the power. You would definitely want to use 230 volts as this allows the motor to run more efficiently.

A thumbs up would be greatly appreciated if this answer is helpful to your free Fixya question.

My new AO Smith motor does not have an L1 IT has L2, L3, and L4 so how do I hook the wires?


There is a schematic on the motor itself to show you exactly how to hook it up. The main thing is knowing whether it's 115 volt or 230 volt connection. Good luck any questions hit me back up.

A thumbs up would be greatly appreciated if answer is helpful for your question. THANK you and GOD BLESS

This is a Speck swimming pool 1.5kw pump I need to replace the motor stator bearings but don't know how to take the pump impeller off


This is the most popular pump frame. The motor will actually have a square flange as an integral part of the motor (not the pump) on the front of the motor with 4 holes (one hole in each corner of the flange). The pump body will be secured to this square flange with 4 bolts, which are outside the round barrel of the motor. Caution: Make certain the square flange is part of the motor; not the pump body. Many pumps are square and may appear to be part of the motor. Removing the motor from the pump will allow you to make certain how the pump is fastened to the motor. How the pump is fastened to the motor determines the basic type of frame.
Note: Also, some 48Y frame motors are actually thru-bolt style; therefore, check the mounting bolts to make certain they are not thru-bolt style as described below.
Not a square flange on your motor? If you do not see a square flange as described above for the square frame motor, then you have a pump body, which mounts to the motor with 4 bolts accessible inside the pump case. This non-square frame will be a thru-bolt style frame, 56J frame, or 56C frame. How to determine if you have a 56J or 56C frame: The pump body mounts to the face of the motor with 4 bolts just inside the circumference of the motor barrel. To see these mounting bolts, you must take apart the pump body and look inside the pump. The bolts will be fastened into the face of the motor with threaded holes. 56J frame: If your pump body mounts into the face of the motor as described in the previous paragraph, and the impeller is threaded onto the motor shaft, then you have a 56J frame. Additionally, the impeller may be secured with a small screw, which is threaded into the center of the motor shaft. If the outside of the shaft is not threaded, maybe you have a 56C frame. 56C frame: If your motor has a shaft with a key-way (small metal key slides into a groove machined along the length of the motor shaft), then it is a 56C frame. These are very rare in today's pumps. If your pump is 20 years old or older, it may have a keyed shaft (56C), but even then is unlikely. The keyed shaft may also have an internal tapped thread to help hold the impeller once it slides over the key-way. Thru-bolt style frame: The motor mounting bolts are the key with this style of motor. Like the name implies, if the pump fastens with nuts to the 4 bolts, which pass all the way thru the motor, then you have a thru-bolt frame. These extremely long bolts (8 inches or longer) will go through the motor. These motors are popular on spas and above ground swimming pool pumps. NOTE: Sometimes these motors are also labeled 48Y frames, but they are not square flanged 48Y frames. Once you determine the frame, click on the link and view some motors to help determine horse power by analyzing the amperage comparisons.

1 Answer

Am I able to step this motor down to 115 ? Plate specifies 230V.only


it depends on how many motor wires you have available to work with .. IF the name plate says 220 volts , not 120 / 220 volts , then no. If there are only 2 wires for the motor, then NO

thoughts?
