Hello all perhaps you would like to see a video of the double reduction gearing in action..?

Carey, do you know what the final drive ratio between the armature and the drive wheels is ? You could position the set screw on the motor shaft straight up and put a pencil mark on one of the wheels and turn the motor by hand counting as you go till the drive wheels make one complete turn. I tried to count teeth but gave up. I like those old K&D motors and have substituted a couple in place of Lionel Pullmor motors in a Hudson and a Lionel 18009 NYC 4-8-2 Mohawk. The seven pole K&D improves slow speed performance quite a bit. j
