The Lubrication System (FIGURE 1-6) consists of an
oil sump, dipstick, pump, oil pressure sender, and falter. The oil
sump is a reservoir for engine lubricating oil. The dipstick
indicates oil level in the sump. A pump draws oil from the
sump and through a screen removing large impurities. The oil
then passes through a spin-on type falter where d impurities
are removed. From the filter, oil enters the engine and is
distributed to the engine’s internal moving parts.
After passing through the engine, the oil returns to the oil sump.
The OIL PRESSURE indicator indicates oil pressure sensed by
the oil pressure sender in the engine. The engine will shut off
automatically if the oil pressure drops to a dangerously low
level. The oil level can be checked when the engine is not
operating.

1-15.1 The Air Intake and Exhaust System (FIGURE 1-7).
consists of an air cleaner assembly, intake manifold, exhaust
manifold and muffler. Ambient air is drawn into the air cleaner
assembly where it passes through the air cleaner element.
Airborne dirt is removed and trapped in the element. A
restriction indicator, located on the air cleaner assembly
housing, displays red when the air cleaner element should be
serviced. Filtered air is drawn out of the air cleaner assembly
through air intake tubes to the air intake manifold where it
passes into the engine and is mixed with fuel from the injectors.
1-15.2 The engine exhaust gases are expelled into the
exhaust manifold. The exhaust manifold channels the gases
into the muffler that deadens the sound of the exhaust gases.
The gases pass from the muffler through the muffler outlet and
are vented upward from the generator set housing.
