Crankshaft: Description and Operation
The cast iron crankshaft has undercut and rolled fillets for improved strength and six counter-balance weights ensure low levels of vibration from the
four throw, five bearing configuration.
The main bearing shells are aluminum / tin split plain type. An oil groove in the top half of each bearing transfers oil into the crankshaft oilway
drillings for lubrication of the connecting rod bearings. A lead/bronze thrust washer is installed on each side of the top half of the center main bearing.
The crankshaft rear oil seal is lipped and is a press fit in the interface of the bedplate to cylinder block.
A torsional vibration damper and pulley assembly is bolted to the crankshaft nose.
