First step was to disassemble the locomotive and clean off all the grime. The pilot removes with a single screw.
You can see the accumulated dirt and grime. The rest of the locomotive was as dirty.
The running gear was dirty and had a bit of rust and discoloration.Nothing too bad, or unusual in a locomotive that's been sitting around for a few decades.
The underside of the smoke unit had a bit of corrosion. I had to remove the plate and take the dremel to it, but it cleaned up.
The tender was just dirty, a good scrubbing with a toothbrush and soapy water cleaned up the dirt.
Here's a shot of one of the tender trucks. You can really see the dirt and corrosion on the truck.
I cleaned off the corrosion and dirt, cleaned the electrical contacts and reassembled everything. I fixed the binding issue. I think it was as simple as one of the running gear rods was not installed properly. After a few cycles of trial and error, I have the wheels turning with out binding.
Set the locomotive on the track and fired up the transformer...and it still does not run. The rectifier in the tender hums, but the motor does not turn and the headlight does not light. Time for some additional research and testing..
