I have an MTH Pittsburgh and Lake Erie 2-8-0 locomotive that the traction tires have come off of. I can't find instructions to do this. The biggest impediment is the connecting rods, I can't see how to get around them. I have loosened a few screws on the bottom in an attempt to get the body off and get at it that way but can't get the right combination. I am leery about just loosening screws until it comes apart for fear I will have trouble getting it back together. Does anybody know where the instructions can be gotten, or possibly have them? I have tried the MTH website but unfortunately the link to the instruction manuals doesn't take you to actual instructions. Any help will be appreciated, THANKS!
