I have a Waterway Executive 56 4hp 2 speed motor. I recently replaced the bearings, and wet end, due to a leaking shaft seal and an extremely noisy motor.. I couldn't just replace the seal unfortunately seeing as for some reason the cover was glued together, and couldn't get to the impeller etc... but that's another story....
So finally got to replacing the front bearing today, as the rear one was perfect.. front was very seized. My issue started when I went to test it to see if the bearing did the trick for the noise. It worked great, and very quiet. I was very happy. Then I screwed on the impeller, and the motor will not start. It just hums, and then shuts off after about 5 or 10 seconds, and then starts the process again, unless I give it a helping hand with a manual turn, or hit the jet button again to get it to high speed. It will then work on low if I hit the jet button again to get it back to the first speed.
I take the impeller off, and it works perfect again.. starts on low all by itself, no issues. It's a brand new wet end. It spins freely by hand, so it's not a stuck impeller... just doesn't have enough power to start on low. I have one capacitor on the top which I assume does double duty. It seemed to have the 50 uf it was supposed to when it was measured with a volt meter, but could this still be the culprit? Could it be reading good, but still be fried? It sounds like it is full of liquid when it is shook. Is that normal? It says it has corrosive fluid inside on the label, but I've never seen one sound like it was full of water before. I hope... it's an easy fix. Just no place in the small town I live in sells them, and I'd have to order online or drive to the city to find one if I needed. But if this sounds familiar to someone else, or
isn't the problem, I won't replace it if I don't have to... hopefully someone has fixed this, or knows how.
