Case SC Its Running ! No oil dipstick?

Ron

The two plugs were specifically for the kero & dis engines, lighter hydrocarbins in those fuels got by the rings & into the crank case. You were supposed to drain off the light stuff each morning (after they sat all night so the light stuff came to the top) & then fill her up so oil ran out of the top plug. Early operator's manuals tell you about it, but later ones don't. Case never made many kero or dis burners, the standard engine was gas. I-H was just the opposite - dis engines were more common, but about the time WW II started, most people ran only gas anyway - the engines didn't seem to care one way or the other. I have a manifold cover & shutters from a '41 H farmall that my father-in-law bought new. They were hanging on the barn wall & he told me about taking them off the day the H came to the farm from the dealer. They never did run it on dis. (My $0.02 worth. jal-SD)
