one of my motors was shot so i ordered another RS-365  DC brushed motor. The Shaft is about 15.6mm long however i do not knoow that much about gears, and i have no idea what the profile / teeth is for the worm gear and wheel gear. Did they glue on the worm gear to the motor? or was it drilled in? When i tired to look into the worm gear i didnt see any drills so i assumed perhaps they used very powerful glue? sorry for sounding a little out of it im not to familiar with gears exactly

How in the world would you consider this a narrow gauge topic?  It clearly is a discussion involving MTH so I moved it to the proper forum.

If motor is bad and you need worm you cut shaft off motor and press out remaining shaft.  Or have a fixture to support worm while removing shaft with press.  That is how I do it.  If motor is good and the worm is bad I cut a slot down the worm without going into the shaft.  Use a dremel with wheel.  The worm will usually split and press off easy.  Otherwise you damage motor thrust assembly.

Pressing on require solid support of the shaft at flywheel end to press new or old worm on.

Make sure you have a measurement of where the worm need to be seated.  G

Do you know the profile of the worm gear and wheel gear?
