Did my 4 hours O.T. and boy does that beer tase good

We had a water well pump go bad the other day- just froze up. We changed fuses, looked for shorts, and couldn't find anything. We even checked for continuity across windings, we found- using our electronic ohm meter, that it registered NO resistance across windings. OK, it's a $10,000 motor, lets call our expert!

Our expert came out and listened to our stories, and ohmed the motor out, checked the motor control pannel- bad motor. Ok, pull the motor and send it in for a bench test/rebuild.

UMmmm,

It tested good on both the main windings and the squirrel cage starter windings.
We got it back and reinstalled it exactly the way we took it out; same wires connected together, and the same amount of thread showing at the shafthead.

OK, fire it up- One of C.P.S.s 75KVA transformers sounded like a freight train, and before we could shut it down, it(the motor) sheared the shaft bushing - the one just above the wellhead.

CRAP! it's 3:30, now we'll have to pull the entire f*cking well shaft- get done sometime around 3AM.

The well guys got out there, and I called C.P.S. to have a look at their transformers. after the well guys got the old sheared coupling off and a new one on, C.P.S. got there to look at their equipment. Everyone's doing their thing and I'm trying to stay out of the way untill they're ready to go.

We reinstalled the well motor, and the well guys showed the water forman what probably happened- the well shaft didn't drop when the motor was off, and he pulled the impellers too tight to the ball couplings. The well guy hit the shaft and it dropped about 1 1/4" inch, then he reset the shaft heigth to the original; he then took up another quarter inch to make up for the stretching of about 500'worth of shaft.

we reconnected the wires, well guys were satisfied, C.P.S. was ready- throw the switch! THUD went the cutoff switch, WHANG went the motor (that's what it's supposed to do), and BUZZZZZZZZ went the transformer untill the starter motor shut off, then everything worked like it was supposed to.

C.P.S. is going to moniter their transformer.

Cool,I'd rather get off at 8PM than 3AM any day. We chalked it up to a little of everything, and no one cause.
