I've got a GE air compressor motor that came with a broken die-cast zinc V-belt pulley on it. The motor shaft is OK, and I've cleaned it up and removed a few burrs. The diameter is 0.672-0.674", which is pretty close to 17mm (0.670"). The OD of the pulley is about 5 inches, and it's got a single 1/2" V belt groove.

Where can I find a similar pulley with a metric bore? McMaster-Carr and MSC don't have any listed. The motor shaft has a flat for a set screw, so I don't need a keyway.

Should I just give up, buy one with a 5/8" bore, and bore it out?

Sounds easiest and best to me.

I would just bore out a 5/8" pulley. Don't think you will find one with a 17mm bore.

You may have a proprietary motor as IEC or metric frame motors do not come with 17mm shaft sizes that I'm aware of at least.

Forget to ask, is there an id plate on the motor signifying as to what it's pedigree is?

The GE motor model number is 5KCR49SN2018X. I couldn't find any info about it. The shaft is about 3/4" long.

Red Jacket used to machine the end of the motor shaft running the motor. You could turn the shaft to 5/8 using that technique.
