Engine Air Cleaner Service Indicator - Inspect
Replace the dirty air cleaner elements with new air
cleaner elements. Before installation, the air cleaner
elements should be thoroughly checked for tears
and/or holes in the filter material. Inspect the gasket
or the seal of the air cleaner element for damage.
Maintain a supply of suitable air cleaner elements for
replacement purposes.
Dual Element Air Cleaner
The dual element air cleaner contains a primary air
cleaner element and a secondary air cleaner
element.
When the engine is operating in environments that
are dusty or dirty, air cleaner elements may require
more frequent replacement.
If equipped, perform maintenance on the pre-cleaner
or the dust bowl before performing maintenance on
the air filter 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 and 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 clean
side of the air cleaner housing or in a remote
location.
