I have a mid 50s Trojan loader that is built around a Farmall M chassis that suddenly started making a loud knocking sound while using it. Shut it down really quick and towed it back to the shop. Pulled the pan and head and found the number two piston had come apart below the rings and above the wrist pin. No bad scoring to the cylinder or to the head so that’s good at least. I’ve never seen a piston do that before. This engine is pretty tired and smoked when running hard but I only use this loader occasionally so just kept the oil level up.. Not sure If I want to try a quick fix by finding a used piston, or try to find another running M engine to put in. I’m sure a proper rebuild of this engine would be several thousand which is far more than this machine is worth. Any Ms I’m seeing for sale all seem to be running around 2000 and are to nice to take apart for just the engine. Not sure what path to take at this point.
