3232814 - 1012A crank case and components

The engine block is cast iron, with high mechanical strength.The crankshaft is supported by means of five main bearings (1).The cylinders are formed directly in the engine block, and are graded into three sizes plus one oversize.The engine block also houses the two counter-rotating shafts, which are supported by a central bush and a ball bearing at the front and rear.There are special channels in the engine block walls which allow the flow of coolant and lubricating oil.At the bottom of each cylinder, there is a jet (2) from which oil is sprayed onto the piston crown. The cylinder block is made from spheroidal graphite cast iron with closed-deck type integral cylinder liners.The crankshaft is supported by means of seven main bearings.The cylinder block/crankcase houses a counter-balance shaft which is supported by means of a central bush and a ball bearing at the front and rear.There are special channels in the engine block walls which allow the flow of coolant and lubricating oil.There is a jet in the lower section which sprays oil to cool the piston skirt and lubricate the gudgeon pin.
