I bought a 5/8” alternator pulley from Speedway and it works perfect. I think they offer other sizes too.

If the belt was bottoming out on that pulley, one needs one size narrower pulley.

Or, a wider belt?

I have a heavy duty belt that is slightly wider. I’m trying that first since I already had it.

I was referring to the color casehardening process where parts are buried in an airtight crucible full of ground bone chips and powdered charcoal, and heated to 1400 degrees in a ceramic kiln or a forge. Once the proper temperature is reached, the contents of the crucible are dumped into a vat of water. The resulting finish has a rainbow of colors, and a thin layer of surface hardening. That process is considered to be the "period-correct" method of treating hand forged and/or cast steel parts for antique firearms like the 1873 Winchester lever actions, etc. For small parts, I use a 2" diameter pipe nipple filled with charcoal powder and ground bone with a cap threaded onto both ends, and bury it in the coals of my forge for a few hours, then unscrew the caps with channel lock pliers and dump the contents into the water bath. I swap phone numbers and email addresses by PM frequently- - - -no problems yet!

What width belt are you using? If you want to fix the one you've got, remove if from the alternator, use a bolt, a nut, and a couple of washers to mount it in a drill press, and use the edge of a big file to deepen the gullet of the pulley. It will take a little time, and the job would go faster with a lathe, but even a hand drill motor clamped in a vise will suffice to spin the pulley if you don't have access to a drill press. Don't touch the sides of the pulley sheaves- - - -just deepen the bottom a little.

I was listed as a heavy duty belt for my truck... very minimal change, but might be enough.
