Watch the video for instruction on how to install this part and also how to determine if this is the correct part.
It is about 4 13/64"" across the face edge to edge, it measures about 3" from the tip of the front to the tip of the sleeve in the back, it also measures 7/16" from the inside of the vane edge to edge. Some of these impellers have a number on them B351-21 if yours does you must measure the overall width of the impeller to get the correct one.
They cast one impelleor with that number on it and they trim the impeller down to the different horse powers so be sure you do measure edge to edge...
