Aftermarket gears?

Liberty used to make 9310 gear sets for the 833 but I haven’t seen any of those since probably the late 1990’s.

I’m of the opinion that you can’t make a gear set that can survive a junk clutch.

If you are breaking 3rd gear it’s almost always the clutch.
Well , I'm sure the gears being about 50 years old didn't help either LOL
