Pac Fab Challenger 1.5 hp pump with a US Motors EB842 replacement motor installed some time before I had the pool (moved in 5 days ago, Murphy's Law in full effect). Noticed the pool wasn't running when it was supposed to, went over to the equipment pad, and smelled the sweet aroma of a burned up electric motor. Tried to start it up and got nothing but a click and more wafts of sweet electrical burning, so I cut off the power at the breaker. Disassembled the pump and looked for obstructions, nothing. Tested the capacitor with my multimeter, it was fine. Tried to spin the motor, and it is seized. I'm guessing its toast.
So, time to replace the motor. First question is whether anyone has suggestions for a good reliable and efficient motor for this pump? Should I just go with another like the one that failed, or a different one?
Second question is how to go about the rebuild, because I've never done this before although I'm fairly handy. I already figure on getting a full replacement gasket set that includes the ceramic pump seal part. The big issue is whether I ought to replace the diffuser and/or the impeller as well. When inspecting the rest of the internals I noticed that the brass ring inside the diffuser is pretty chewed up. So I'm thinking I ought to replace that piece as well? The impeller part that it interfaces with also looks kind of scratched up, but not in too bad of shape. But should I go ahead and replace it as well just for safe measure? See pic of diffuser below sorry for the low quality I took those with my phone.
If I were a betting man, I'd bet that this chewed up brass ring had something to do with the motor burning up too. Which is weird because it wasn't making too much noise or anything. Thanks in advance for the help folks, this is my first pool so I'm a total novice at this stuff.
