I know many don't care to look at this, but I find all engines interesting and this one is no exception. Very different 4 main set-up and the four and a half ft long crank is heavy for a 110 hp tractor. This had #6 Con-rod brg weld itself to the crank due to operating with a very low oil level. The rod and journal got so hot it ignited crankcase vapors, causing a Minnie explosion that blew out valve cover gaskets. We will just replace the crank because a good used one is only a few dollars more than repairing the old one and then we do not have to worry about that heat stressed journal. Rod.
