Engine Air Cleaner Service Indicator - Inspect
Inspect the clean, dry air cleaner element. Use a 60
watt blue light in a dark room or in a similar facility.
Place the blue light in the air cleaner element. Rotate
the air cleaner element. Inspect the air cleaner
element for tears and/or holes. Inspect the air cleaner
element for light that may show through the
fi
lter
material. If it is necessary in order to con
fi
rm the
result, compare the air cleaner element to a new air
cleaner element that has the same part number.
Do not use a air cleaner element that has any tears
and/or holes in the
fi
lter material. Do not use an air
cleaner element with damaged pleats, gaskets or
seals. Discard damaged air cleaner elements.

Engine Air Cleaner Service
Indicator - Inspect
(If Equipped)
Some engines may be equipped with a different
service indicator.
Some engines are equipped with a differential gauge
for inlet air pressure. The differential gauge for inlet
air pressure displays the difference in the pressure
that is measured before the air cleaner element and
the pressure that is measured after the air cleaner
element. As the air cleaner element becomes dirty,
the pressure differential rises. If your engine is
equipped with a different type of service indicator,
follow the OEM recommendations in order to service
the air cleaner service indicator.
The service indicator may be mounted on the air
cleaner housing or in a remote location.
