The Lubrication System (FIGURE 1-6) consists of an oil
sump, dipstick pump, oil pressure sender, and filter. The
oil sump is a reservoir for engine Iubricating 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
filter where small 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.

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.

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.
