They've got a fair number of 1/4" bore, but you need to know pitch, face
width, etc.
Here's an example:

Good luck with finding one. There are many gear suppliers online but buying
a small quantity is challenging. I would try McMaster-Carr. Maybe another
option is 3D printing if you have solid modeling software. Make sure that
the plastic gear is tight against the rotating shaft to prevent slippage and
wear. I put a screw in the side of my housings to keep the potentiomenter
bracket in position. About a decade ago I needed a couple of the steel
gears that fit on the 10mm windshield wiper motor shaft and was unable to
purchase them, at least not for an affordable cost. I wound up having to
buy gear stock and machine them myself on a lathe.

Does anyone know of a source for the small plastic gear that fits on the
multi-turn pot inside the Tic-Gen ring rotor motor box? The one that lost
some teeth
had 55 teeth, was 7/8 inch OD and had a metal insert to fit the 1/4 inch
shaft of the pot. I have a replacement from the pot removed from a
slave motor which didn't need the position indicator, but I would like
to have a replacement for just in case. These motors were late 1990's
vintage, with the sheet metal box, and the 1022 size ring.
I don't want to have to go to the external pot assembly TIC-Gen uses now.
