2.3.12. Lubrication system
z The engine runs with the forced lubrication system. Oil pressure is generated and
supplied by gear revolution of the oil pump, which is meshed directly with the
crankshaft located at the rear side of the cylinder block.
z The oil pump sends oil sucked by the oil pan with the intake pipe via the oil filter
and oil cooler. Then, oil is supplied to the crankshaft bearing, camshaft bearing,
and rocker arm for lubrication. In addition, the turbo charger is also connected to
the engine lubricant circuit, and supplies oil for engine break operation.
z Lubricant is sprayed around cylinder blocks and timing gears. Each cylinder has
the oil injection nozzle to cool down the inside of the piston. Engine oil is cleaned
by passing through the oil filter.
2.3.13. Engine oil
z Check the oil amount with an oil level gauge, and refill oil, if necessary. Check the
oil level after stopping the engine. If the engine was running, measure the oil level
after 5 ~ 10 minutes, so that oil is returned to the crank case. The oil level should
be between upper and lower limit of the gauge.
z Engine oil should be replaced regularly, and the oil filter cartridge should be
replaced at the same time.
