That was my first thought. These gears don't fail because they wear out
in use, they fail due to stresses generated by them being pushed onto the
speindle. Severaal of mine have failed without being used.
Personally, I'd want to use a metal gear that was a sliding fit onto the
motor sprindle, and then fix it on with a suitable Loctite.
Somebody else suggested replacing all 3 gears in each train. Difficult.
The last gear is part of the platten or cable drum, and is, in fact 2
gears wit han anti-backlash spring IIRC. All these parts could be made,
but you're not going to find them off-the-shelf. And if you're going to
start 'm,king swarf'[1], why not just make the pinion you need.

You can just throw your bad one away and get a
new one. There's a guy
selling 825 printers for $10 the each, NOS on Yahoo!:
That's one of the reasons I bought a handful of printer mechs from
Alltronics or Electronic Goldmine or one of those guys... spare gears.
The problem is that what I got was about 90% defective.
