Several years ago I bought a Spectrum 3-truck Climax from Bachmann with DCC/Sound. It ran okay for a while, then quit. I sent it back and they repaired it, and it worked okay...for another while, then died again. The sound works fine, and I think I can hear the motor, but it won't move and I suspect a Chinese gear is cracked inside. Bachmann no longer has parts or repairs the I am trying to disassemble the beast, but have so far only been able to remove the coal bunker behind the cab and get the cab loose except for a bell rope or something. Anybody have a clue as to how to get the rest of the boiler off to expose the mechanism?
