I have a Joe Works Hon30 on a Bachman 0-4-0 chassis that has the plastic gears in between the metal wheels. Both gears and hubs are split, I made sleeves to close the split witch worked but one of the gears didn't close and is creating a problem with the mesh. It hangs up when it gets to the split when turning by hand so I know it's not going to work. If anyone has a fix or the gears please let me know. Thanks T.C.
