After reading your response to this post, I went to the parts diagram and found there were 2 parts that show for the impeller for this motor. They both look the same in the pictures on the site but there is one slight difference between them. One has what appear to be very small nipples that stick out between every other blade. If you look at the impeller center, those small nipples appear on the outside of the circle between every other blade. I dont know if they have any purpose at all or if they are just extra rubber from the manufacturing process. The parts diagram is for my exact motor but the diagram shows one impeller in the picture diagram, 2 impellers on the list. Not sure why.
Here is the link to the page showing the diagram and parts list to the right sie of the page. Let me know what you think…….
