Crankshaft, Bedplate And Oil Pan Components: Bedplate
The bedplate is of an aluminum alloy structure bolted to the bottom of the cylinder block to further improve rigidity and to retain the crankshaft. The 7 cast iron crankshaft bearing caps are cast in the boreholes.
A windage tray attached to the underside of the bedplate isolates the oil pan from the disturbed air produced by the rotation of the crankshaft, to prevent oil aeration and improve oil drainage.
