This is an original crankshaft for a 1 hp International Harvester Mogul Jr gas engine. It is in good used condition with no cracks, breaks, or repairs of any kind and includes the pinion gear which is also in very nice shape. I believe this crankshaft fits both the flat top and slant top engines. This crankshaft measures about 1 1/8 inches in diameter in the bearing journals and 1 inch in diameter where the flywheels mount. It is about 17 1/2 inches long. The bearing journals need to be polished and the connecting rod journal a bit more but I think with a little effort they will clean up nicely. After that I think this crankshaft should be ready to be used in an engine. Mogul Jr parts don’t come along very often so if you need one for any reason here’s your chance. The pictures tell the story. I can be reached at 262 573 193 1 if you’d like to talk about it.
