Update: they came today, and they’re installed. Installation was a bit of a pain, though I could have made it somewhat easier by reading the directions more carefully the first time (you’d really think at my age I’d have learned to do that by now)...oh well.

Unfortunately, it didn’t seem to remove the “clunk” at motor startup as I’d hoped. The tension seems to be right (maybe a tiny little bit loose, but I’m out of adjustment room), so I don’t think the belts were the cause. Oh well, still a worthwhile experience.

Thanks again to those who advised on this.
