Engine System - Operation/Lubrication System LUBRICATION SYSTEM The engine has a pressure lubrication system. In the main it consists of the gear pump (2), filter strainer in the suction pipe, full flow oil filter (6), oil cooler (5), adjustable oil pressure regulating valve (8), oil by-pass valve (3) and an electrical pressure warning switch (17). Lube oil holes in Nos. 1, 3, 5 main bearing oil grooves are provided to direct oil to the camshaft bearings (15). The lower idler gear is lubricated by splash oil. A drilled passage from the rear camshaft bearing through the cylinder block and cylinder head supplies lubricating oil to the rocker arm shaft.
The pump draws lubricating oil from the crankcase through a strainer (1) and suction line and pumps it through an oil line via the oil cooler (5) to the oil filter (6) and to the main oil gallery (14) of the cylinder block. Direct oil passages from the main oil gallery provide lubricating oil to balancer shaft bushings (9) and the shaft of the turbocharger. The front right-hand balancer shaft bushing is lubricated directly from the oil pump. From here oil is forwarded under pressure to the main bearings (10) and spray jets (11) to cool the pistons. Drilled cross passages in the crankshaft distribute oil from the main bearings to connecting rod bearings (12).
