American Flyer Locomotive 3745 & 3778 Parts List & Diagram
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 American Flyer Locomotive 3778 Texas Pacific GP7.
American Flyer had three basic types of diesel trucks. GP7 trucks with two powered axles, PA/PB trucks with simulated three powered axles (also used on the EP-5 Electric style locomotive) and I the Baldwin diesel trucks had two powered axles. The GP7 locomotives were the B-B type like the Baldwins.
Diesel Locomotives used a different naming convention compared to Steam. Steam followed the Wythe naming system vs. the Diesel system that looked at the number of axels instead of the number of wheels.
