Spare Parts Kit, R8, Mini Mill

The metal motor gear feels noticeably sturdier than the plastic original, and having those extra fives fuses on hand is a relief. I've already swapped the 14-tooth gear in, and it's running smoothly without any binding.

Having the 30-tooth intermediate shaft gear and the 29-tooth spindle gear together in one kit saved me from ordering separately. The metal motor gear feels much sturdier than the old plastic one.

Finally got the metal 14-tooth motor gear in hand—that plastic one was bound to fail, and swapping it in took maybe ten minutes. The extra fuses and spindle gear are a nice safety net for the next inevitable hiccup.
