I have a hayward Superpump with a 1.5HP motor. Unknown age, came with the house I purchased August 2014.
When I went to start it for the first time this season it would buzz and not begin spinning. I assume something was jammed in the impeller and so I attempted to access it, however 2 of the housing cap screws (big bolts with 9/16 hex heads) were rusted in place. I was able to free one with some sea-foam, but the other was badly stuck so I cut the head of with a sawsall.
Turns out the main shaft was seized (i was able to remove the impeller without locking the shaft from the rear). After applying some more sea-foam I was able to get the shaft to turn manually and for quick burst with power before re-assembling.
After re-assembling with only 3 bolts tightened, it started up fine but leaked pretty vigorously from the corner with the busted bolt.
I got a bolt extractor set and to remove the bolt, but instead I pulled out the entire brass threaded insert into pump/strainer housing.
I purchased a kit that had a replacement for this and installed it, as well as a replacement seal assembly since the seal looked worn and was of unknown age.
I wasn't able to get the replacement threaded inset to stick in place as intended, but with some patience and gorilla glue the job eventually got done.
Upon re-assembling and restarting the pump there was still some leaking, and after about a 30-60 sec there was a big puff of white smoke and it shut off. I figured the start capacitor had blown, and confirmed after removing it. Its odd that it would go out after it had already started pumping so I suspect the start switch governor stayed closed either because it was slightly rusted or it never got to full speed, eventually causing the start system to overheat.
With the capacitor removed and the motor detached I could test start it, so nothing seemed to be jammed or seized.
I purchased a replacement start capacitor and some rtv sealant to go around the imperfectly sealed corner. I also played with the start switch to make sure it depressed and sprung back up properly.
After re-assembling everything, it started up well with no leaking, but very quickly started smoking. Not a big poof but a more constant white smoke, and after shutting off it buzzes instead of starting again. So basically back to square one.
Any advice? Are the windings in the motor burnt out? I can remove the capacitor and check it with a meter, but I assume it burned out again. At this point I've been working on this for a month that I could have been swimming, and considering just calling a pool service company.
