Rich,
I do not know how quickly you would want the reversing unit, but yes it, as a matter of fact both reversers will be available, but this is one of my not at the head of the line projects. The pair I have do not have sound, the sound unit I do have is in an AC B-unit. I found the disassembly as you did by carefully removing the screws, I actually removed all of them from the bottom of the engine not knowing which were actually holding it together.
I had one truck that would lock up also, but on this loco one of the screws fastening the two halves of the gearbox together was stripped and the two sides were not tight allowing the gear train to shift thus causing it to lock up. Lube! I was surprised to find the amount of oil and grease in the gearbox, when I am ready for the final reassembly they will be totally cleaned and re-lubed. From what I have read on the forum it is not unusual to find the gears split, fortunately for me none of mine are split. I need also to purchase at least one axle though, I don't know why but one of the axle bearings is extremely sloppy on the shaft. I found the second unit was set to start in reverse, the motor lead was not soldered but just wound around the motor post. I do have one of the units running, it runs quiet and smooth as you stated, but the second needs more extensive repair and some parts that I hope I can get from AM.
I found the same as you that the engine has only one headlight so I do not know if the reversing board supports directional lighting. On my engine in reverse the headlight does not illuminate. You could always use an led, wired for dc, from Evans Designs, and attach to the motor leads for the rear light.
Thanks Rich for your input, if you would want the reverse unit soon contact me off the forum, I do have a TMCC board I could put in the running locomotive. Before removing it I would take a pic of the E-unit wiring and send it to you.
Ray
