How does one get the shell off of the Athearn Challenger tender? I have removed the coal load to expose one screw there (not sure if it matters), I have removed the two at the rear underside and taken the back end off, but still no movement. Not wanting to apply brute force to a several hundred dollar locomotive, I thought someone might have already figured this out. Any help GREATLY appreciated. BigBoy4884 :tb-hissyfit:
If I remember correctly, I believe there is a hidden screw somewhere. If you still have the manual it came with, there is an exploded diagram included. A study of that may reveal the proper procedure. BTW, welcome to TrainBoard!
NOOOO! The online manual with exploded diagrams can be found here. It looks like there is a screw under the rear most bunker hatch and under the coal load or the level gauge for the oil version.
There are some truly excellent instructions on this site. I managed to follow them! http://www.sdsons.org/how%20too's/Decoder%20installs/Big%20Boy/loksound%20bigboy%20install%20page.html Cheers, Ted
