American Flyer Locomotive Worm Drive Instructions
This is the service bulletin furnished by the A. C. Gilbert Co. to authorized service stations to aid them in the service and repair of American Flyer equipment. Specifically, this bulletin is for the American Flyer Locomotive Worm Drive.
There are two main power sources for Gilbert motors, AC and DC. For the most part most are AC motors. There are a handful of other variations across the locomotives including where the whistle and smoke units are located. American Flyer Steam Locomotives entirely used worm drive motors. The advantage of worm drive motors is that they allowed the model train to start slowly without being lurchy. Effectively a smoother start as the engineer provided power made for a more realistic toy train model experience. In addition, worm drive motors enable the locomotives to pull longer trains.
