This is the first time I try to repair my pool motor so any advise is appreciated. I tried to remove the impeller of Leslie Hydramax II but was not able to do it. I was able to separate the pump housing and had the impeller exposed. I assume that I just need to remove the cap on the from the center of the motor on the end opposite the shaft so I can access the end of the shaft. But somehow I can't get the cap off. And I am not even sure if my assumption is correct now. Anyone can confim what I tried to do is correct? I just want to know where I can access the shaft to prevent the shaft from turning so I can remove the impeller. Thanks.
