Quartering LGB Mogul
I have a D&RGW Mogul 21181. It wasn't getting connectivity to the track through the engine, only the tender. So I took it apart and fixed that problem. I have taken it apart several times before to install a DCC decoder and replace the smoke unit with no issues. This time, it is making a lurching motion and driving slow. So I took it back apart to make sure the side rods weren't binding. Now it is worse. I think maybe they aren't quartered correctly. I am also ordering idler gears and new grease with my next order just in case. What is the best way to ensure the wheels are quartered?
