The crankshaft is made from cast iron. Seven counter-balance weights ensure low vibration levels. An oil groove in the upper half of each main bearing transfers the oil into the crankshaft for lubrication of the main bearings. The upper center bearing shell has an integral thrust washer to counter end float.
The crankshaft is located high in the cylinder block and is retained in position by an aluminum alloy bulkhead bearing support which strengthens and braces the cylinder block.
