How to determine weather you have 48 or 56 frame bracket mount motor.
Measure the distance between the "Thru Bolts" on the motor that attach to the wet end/pump. Use the references below to find out which one you have. Although motors may be slightly different in appearance, the measurements below are accurate for all 48 and 56 frame bracket motors.
Note: "Bracket motors are recognized by the welded bracket stand found on the bottom of the motor.

48 Frame Shown 3 5/8"
56 Frame Shown 4 1/8"
You can also find the frame size of the motor on the spec sheet, that is located on the side or top of the motor. This method can be confusing because some manufactures such as AO Smith and General Electric call their 48 frame motors 56 frame. Again the best way to determine what you have is by measuring the thru bolt distance.
