Engine Air Cleaner Element (Single Element) - Inspect/Replace
Vacuum Cleaning
Vacuum cleaning is a good method for removing
accumulated dirt from the dirty side (outside) of a
primary air cleaner element. Vacuum cleaning is
especially useful for cleaning primary air cleaner
elements which require daily cleaning because of a
dry, dusty environment.
Cleaning from the clean side (inside) with pressurized
air is recommended prior to vacuum cleaning the
dirty side (outside) of a primary air cleaner element.
Note: Refer to “Inspecting the Primary Air Cleaner
Elements”.
Inspecting the Primary Air Cleaner
Elements

Illustration 27
Inspect the clean, dry primary air cleaner element.
Use a 60 watt blue light in a dark room or in a similar
facility. Place the blue light in the primary air cleaner
element. Rotate the primary air cleaner element.
Inspect the primary air cleaner element for tears
and/or holes. Inspect the primary air cleaner element
for light that may show through the filter material. If it
is necessary in order to confirm the result, compare
the primary air cleaner element to a new primary air
cleaner element that has the same part number.
Do not use a primary air cleaner element that has
any tears and/or holes in the filter material. Do not
use a primary air cleaner element with damaged
pleats, gaskets or seals. Discard damaged primary
air cleaner elements.

Engine Air Cleaner
Element (Single Element) -
Inspect/Replace
Refer to Operation and Maintenance Manual, “Engine
Air Cleaner Service Indicator-Inspect”.
NOTICE
Never run the engine without an air cleaner element
installed. Never run the engine with a damaged air
cleaner element. Do not use air cleaner elements with
damaged pleats, gaskets or seals. Dirt entering the
engine causes premature wear and damage to engine
components. Air cleaner elements help to prevent air-
borne debris from entering the air inlet.
NOTICE
Never service the air cleaner element with the engine
running since this will allow dirt to enter the engine.
A wide variety of air cleaners may be installed for use
with this engine. Consult the OEM information for the
correct procedure to replace the air cleaner.

Engine Air Cleaner Service
Indicator - Inspect
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 element or in a remote location.
