I have an Athearn Genesis MT4 that ran great up until 3 weeks ago, however something got jammed in the mechanism (or so we think) and it now will not move. I sent it to a friend of mine who is a master modeler in the narrow and standard gauge world and he couldn’t figure it out after tinkering with it and the exploded parts view. I was wondering if anyone here has taken one of them apart, and if so do you have a description or pictures of how it comes apart. It would be much appreciated.
I realize this thread is ten years old but I recently purchased a used DC MT4 off ebay and while it appears to run the trailing truck under the cab is causing a short unless it’s running on it’s rim/not making contact with the track despite it not being supposed to draw power. I’m trying to see if I can insulate the trailing wheels somehow with traction tire(s) but this may be a potential cause for OP’s issues as well
