I recently acquired a Lionel PW 2035 locomotive. It runs and smokes well but needs some TLC. I need to clean up some surface rust on the drive rods and decided to remove one from the engine. I discovered that the bolt holding the drive rod to the crosshead is not a standard threaded fastener. The Machinery's Handbook lists it as a metallic drive screw typically used for permanent applications. I tried to reinsert it into the crosshead, but it doesn't go in easily. It has a 5/32 hex head. Here's a photo.
My question is, can I reinsert this screw without damaging the crosshead? I would find it hard to believe that someone hasn't come across this type of assembly while overhauling a PW locomotive. Happy New Year everyone!
