Bachmann Climax Overview As of 2016, there are 2 versions of this unusual geared locomotive. The first version was released about 1999 or earlier. A newer version with the socket was released about 2014 or earlier. The differences are that the newer one: has the modified Aristo socket the fram is longer the bunker is longer 4 wires from the truck to the chassis as opposed to 2 the electrical parts to bring the power from the trucks to the chassis have changed. Disassembly Removing fuel bunker Pictures and procedure courtesy of TOC (Dave Goodson) How the #@$! do you remove the bunker? See the 2 small valves in the front corners of the bunker? Lever them out carefully. Hey, there are screws down there! Lift the front edge of the bunker A LITTLE, you are NOT done yet, relax. There's still 2 tabs holding it in place, you need to push them each forwards, but do NOT use a sharp blade, a thin putty knife, or a ground-down x-acto blade. Do each corner separately. Bingo! Thanks Dave!
