John, the blueprint sheet in Mr. Williams' second post says the gear ratio is 12:1. Based on my efforts at counting teeth, and the author's assertion that the drive coasts, that seems about right to me. Of course the 18:1 back-drivable worm gearing that Lionel used in the 700e wasn't too shabby either!

Thanks Ted. I missed it the first time. You know something I have wanted to try with a pullmor motor was to pull the wire off and skew the armature laminations before rewinding it. Wonder if anyone has tried this. Would like to know if they thought it worth the effort. I am curious what affect on low speed growl it might have. Think I will start a thread on that tomorrow. j
