Pat, on some of the RailKing locos, the worm gear is not pressed onto the motor shaft. So there's no reason in the world why you couldn't upgrade a RailKing Mohawk or even last year's LionChief Plus Berkshire to a (smaller) Pittman motor. I think the 8692-series is about the same size as the common, crummy RS-385. The flywheel is held on with a set screw, so no problem there. The only issue might be the spacing and diameter of the mounting holes. But you wouldn't know nuthin 'bout that!
