Topic tags/keywords: question compressor motor fix recycle repair

My compressor motor lost its key, and the pulley that was attached chewed up the shaft and keyway pretty good. The keyway is beyond filing and/or grinding. Other than that there is nothing wrong with the motor. Runs, is quiet, has maybe 10 hours on it max.

The motor new is over $400.00

BUT: I called our local electric motor repair facility and he said the shaft would have to be “re-metalized,” whatever that means.

He said it wouldn’t be cheap either. He didn’t elaborate on the price.

So here’s my dilemma: the compressor company already sent me a free new motor and the compressor is up and running. The old motor is pristine except for the shaft.

Should I just recycle it? Throw it away? Give it away? Have it re-metalized and then try to sell it?

What’s your advice?

keep it till u decide what to do, also find out the price to re-metalize it just in case u want to sell later.

As you have nothing invested, try to build up the shaft with JB Weld. It’s a two part epoxy-like confection that after 24 hours can be machined like steel. Then, as Skeezics suggests, use a grade 5 or grade 8 set screw to secure it. You will always find a use for something right after the garbage truck leaves.
