CONSTRUCTION
The stiffening crankcase assembly is made of aluminum alloy.
The No. 2 oil pan sub-assembly is made of steel.
The oil pump assembly is installed within the stiffening crankcase assembly to make the engine compact.
To improve serviceability, the stiffening crankcase assembly has been designed so that it can be removed without removing the No. 2 oil pan sub-assembly and the oil pump assembly.
The air conditioning compressor brackets are integrated into the stiffening crankcase assembly.
Oil passages have been provided in the stiffening crankcase assembly that allow the oil to flow from the cylinder head, through the cylinder block, to the area below the baffle plate to prevent the engine oil from becoming agitated due to the rotation of the crankshaft, thus reducing friction.
