Oil FilTER CARTRIDGE
After lubricating, the lu bricating oil brings back various
particles of grit and dirt to the oil pan. Those particles and
the impurities in the lubricating oil can cause wear or seizure
of the engine parts. It may also impair the physical and
chemical properties of the oil itself.
The lubricating oil, which is force-fed by the pump, is
filtered by the filter cartridge with the filter element (2).
When the filter element accumulates on excessive amount of
dirt and the oil pressure in the inlet line builds up by 98 kPa
(1.0 kgf/cm 2 , 14 psi) more than the outlet line, the bypass
valve (1) opens to allow the oil to flow from the inlet into
the outlet line, bypassing the filter element.

[4] Oil PRESSURE SWITCH
The oil pressure switch is mounted on the cylinder block and
is led to the lubricating oil passage.
When the oil pressure falls below the specified value, the oil
pressure warning lamp lights.
