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

Do not use paint, a waterproof cover, or plastic as a
protective covering for storage. Restricted air flow
may result. To protect against dirt and damage, wrap
the elements in Volatile Corrosion Inhibited (VCI)
paper.
Observe the service indicator. Clean the air cleaner
element or replace the element when the following
conditions occur:
• The yellow diaphragm enters the red zone.
• The red piston locks in the visible position.
• The air restriction reaches 3.7 kPa
(15 inches of H2O).
Place the element into a cardboard box for storage.
For identification, mark the outside of the container
and mark the element. Include the following
information:
Inspect the service indicator daily for cracks, holes, or
loose fittings. If any of these conditions are present,
repair the service indicator or replace the service
indicator.
• Date of cleaning
Test the Service Indicator
• Number of cleanings
Service indicators are important instruments.
Store the container in a dry location.
For more detailed information on cleaning the primary
air cleaner element, refer to Special Publication,
SEBF8062, “Procedure to Inspect and Clean Air
Filters”.
• Check for ease of resetting. The service indicator
should reset in less than three pushes.
• Check the movement of the yellow core when the
engine is accelerated to the engine rated rpm.
The yellow core should latch approximately at the
greatest vacuum that is attained.
