Dennis,

You might as well just crack one open. The drill motor gearboxes are 3 stage planetary gears. The gear ratio depends on which stages are locked. Though as I recall all of the stages use the same gears.

A good mechanical engineering reference book like the Lindberg PE exam book or "Mechanical Engineering Design" by Shigley will have the formulas for the effective gear ratio if you have the numbers of teeth.

Actually, taking one apart would be a good educational exercise. Putting one back together is even more of one. Last year we had to do this several times to rebuild gearboxes when we broke components. Once you learn how it's not a big deal.

I'd tell you how, but I don't remember off hand and the nearest gearbox I know of is several miles away...

Chris
