Oil galleys

This is a horizontal shaft engine, the groove is cut in the crankcase "bearing". The kohler horizontal shaft has no bushing or bearing between the crank and the crankcase, so the oil channel on the crankshaft cut into the case on one side producing the "raised" ridge between the oil galleys. My question lies in the machining done to the oil galley lookslike they were cut in with a chainsaw, not a die grinder. The crankshaft being much harder than the case, has no visible scarring, its still a mirror finish.
