Re: RS-550 and AndyMark am-0928 pinion
All,

All of the RS-500 series motors (Fisher-Price Motors, am-0912 motors) all have shafts of the correct size to fit this pinion. They have a 1/8" diameter motor shaft with a knurl that lets the 1/8" id bore of the pinion gear press on to the shaft nicely.

The BaneBots motors don't have this nice feature. The above suggestions may work nicely, but if they don't, adding a set screw will do the trick.

Sincerely,
Andy B.
