Crankshaft: Description and Operation

The crankshaft forging has ground journals, which have been hardened by tenifer treatment to provide a hard, nonmetallic surface coating with
hard-wearing properties. There are five main bearings, with the middle (No. 3) bearing also serving to locate the shaft axially. Lubrication is provided
through drilled oil-ways in the shaft. All main bearing shells are replaceable.
