Impurities in engine oil can cause to wear and seize
components
as
well as impairing the physical and
chemical properties of the oil itself. Impurities contained
in
force-fed engine oil are absorbed on the filter paper for
removal
as
they pass through the filter element
(1).
When the filter element
is
clogged and the oil
pressure in inlet line builds up by
98
kPa
(1
.O
kgf/cm2, 14
psi) more than the outlet line, the bypass valve
(2)
opens
and the oil flows from inlet to outlet bypassing the filter
element.

The oil pressure switch is mounted on the cylinder
block,
to
warn the operator that the lubricating oil
pressure is poor,
If the oil pressure falls below
49 kPa
(0.5
kgf/cm2,
7
psi), the oil warning lamp will light up, warning the
operator.
In
this case, stop the engine immediately and
check the cause of pressure drop.
