Hello all. I had to replace my pool pump over the weekend. Replaced mid-day on Saturday. Everything worked well with no problems. Had to replace due to water leak, which caused bearings to rust in old motor. Replaced seals and thought everything was alright. Noticed some water late Saturday so I shut it down until I could investigate. Cranked it up Sunday morning, and within seconds I smelled a burning smell and the motor started smoking. Immediately shut off. Didn't have a chance to break the motor back down yesterday.
My initial thought has to do with the motor shaft seal. The seal I ordered didn't fit. The piece that fits into the faceplate was too large. So I rigged it up, I used the old piece, but used the new spring piece for the impeller. I'm thinking something might be incompatible here. But why didn't it cause me any problem on Saturday. It ran for 5 or 6 hours without issue on Saturday.
Again, I haven't broken the motor down yet to see if I can tell what was burning, but anybody have any initial ideas. FYI- when I turned it on yesterday, I was able to isolate the water leak, the PVC running from the pump basket to the sand filter. It is leaking at the union, so I'll have to replace that connection and pipe.
