Why a new crank case ? You could get a new lug welded back on, and the whole area beefed up - probably cheaper and quicker than getting a "Good" crankcase And it may be possible with a minimum of engine stripping down. I can't see why a 12 volt starter would put more load onto the crankcase, the power output of the starter motor is likely much the same. Was there any possibility of a water leak into one of the cylinders causing the piston to 'hydraulic' and then put excessive load back through the starter?
