Reply to "What did you do on your layout today?"

Today I decided to try fixing a nagging problem with my K-line Scale K4s. A part of the drive wheel rod connections on one side have been binding. There is brass part that attaches to the side of the shell secured by the flanges of the part and a screw. That part has an arm that secures the ends of two valve gear rods. One end of a rod is secured to a connector on the center drive wheel. After several binding events one of the brass parts suffers bent flanges. After several attemps to fix it I finally removed the brass part and the offending connection rod. I am going to try to find a new brass part. It might even be the same part is on the Lionel remake of the engine. In any event, the loco now operates without binding. Maybe it's time to look for a Legacy K4s.
