I have 2 of the newer Athearn RTR RS-3's. While I really like the detail work that was put into the body (shell) of the locomotive, the motor and frame are basically Athearn "Blue Box".
I've begun to have some pretty serious problems with the trucks on both of my RS-3's and have found that the wheels are spinning freely on the geared axles. They are also out of gage now. I have removed the wheels from the trucks and simply can't believe how easily the steel wheels spin inside the center geared axle.
The fact that this is happening to both of my RS-3's tells me that it may not be a isolated incident (but who knows).
Does anyone know of (outside of more Athearn wheels and axles) what I can use as a replacement? These wheels and gear sets look indentical to the Proto 2000 GP-7, GP-9, GP-18 wheel and gear sets that were known to crack along the teeth of the gear.
