Restoring An American Flyer Engine

Hi,
I am restoring my American Flyer 282 engine. Whatever that is in the coal car isn't responding. Voltage gets to it but nothing
happens. What is that thing? It looks like a motor that turns a cylinder (electromechanical commutator?). I think it has something to do with reversing the train. What is the proper way of fixing this mechanism?
Is it safe to put voltage directly on the engine motor to see it works?
Thanks, Gary

The device in the tender is the reversing unit. The most common problems with it are the mechanism that rotates the drum gets dirty and sticks, or the contact fingers that ride on the drum wear out. Worst case is the operating coil is burned out and the entire unit will have to be replaced.
There should be a direction locking lever sticking out of the bottom of the tender. You can use it to manually operate the drum and see if the operating pawl is sticking. If it is, usually a shot of contact cleaner will free it up. If it works manually, but not with power connected to the tender pick-ups, check that none of the wiring has broken loose. I've seen some where the wire was broken, but the cloth insulation was holding it in place so it looked okay until you touched it.
If you need parts, the numbers are:
XA9612CRP - Top Fingers XA9612BRP - Bottom Fingers XA8716 - Drum
Parts can be obtained from Train Repair Parts http://www.trainrepairparts.com/trainrepairparts.htm or RFG Co. http://www.rfgco.com . Both have exploded view diagrams and wiring diagrams, but the TRP diagrams are easier to navigate. The diagram for you loco can be found at:

If your loco has the four-pin jack panel, you can test the motor directly by connecting the the lower jack to the one above it on each side of the jack panel with a jumper wire. A heavy paper clip will do in a pinch. Then connect a power lead to each jumper. Like this:

I polished the drum and fingers. The reverser now works.
The engine is missing the wires to the motor winding. (My nephew had possession of the train for a while and reportedly tried to "fix" it.) I found a wiring diagrams on the 'net but it isn't clear where the wires connect to the winding. Where? It might be moot - it looks like the winding is broken.

The winding connects to the two bottom jacks, and the motor brushes connect to the two top jacks of the jack panel.
If the winding is completely shot you can get a Timko can motor conversion kit for about $30.00 or so. You can check them out at:

Well, it's about time someone posted something to do with s-gauge on the ng ;-). Long live 1/64! Sincerely, from a fan of all things made by A.C. Gilbert before 1960,
