Congratulations!!! Thanks for finishing the story.

As an interesting side effect, the tractor now has more power. I assume there was a fair bit of drag on the engine from the belt slipping around the locked up alternator instead of spinning it.

I am certain that nobody around here would have a bearing. After I get a replacement, I will repair this one as a spare. If I can get one for ~$100 off ebay, that's the way I will go. I can't risk being without the tractor to hunt a bearing. If we get snow and it's not running, I can't leave the house.

I really don't have any interest in converting it to another alternator. It's just not worth it to save $20. I doubt the side cover would go back on with a 10si on it, it's twice the size of this one. Yes, they have more output. But, this one does what I need it to. Charge the battery and run 2 lights.

As for why it failed, the belt is not overly tight. Machine has about 580 hours on it. Guess it was just it's time.
