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 airborne debris from entering the air inlet.
Never service the air cleaner element with the engine running since this will allow dirt to enter the engine.
If the air cleaner element becomes plugged, the air pressure can split the filter material of the element. Unfiltered air will drastically accelerate internal engine wear. Your Cat dealer has the proper air cleaner elements for your application.
- Check the precleaner (if equipped) daily for accumulation of dirt and debris. Remove any dirt and debris, as needed.
- Operating conditions (dust, dirt, and debris) may require more frequent service of the air cleaner element.
- Replace the element when the air restriction reaches
3.75 kPa (15 inches of H2O).
- Replace the element when the red piston of the service indicator locks in the visible position.
- The air cleaner element may be cleaned up to six times.
- Replace the element at least one time per year. Perform this replacement regardless of the number of times the element was cleaned.
Replace the dirty paper elements with clean elements. Before installation, thoroughly inspect the element for tears and/or holes in the filter material. Inspect the gasket or the seal of the element for damage. Maintain a supply of suitable elements for replacement purposes.
- Open access door (1). Remove element (2).
- Seal the air inlet to the turbocharger with a cover or tape. This cover will help to prevent dirt from entering the turbocharger when the body of the air cleaner is cleaned.
- Inspect a clean, dry air cleaner element for good condition.
- Remove the tape or the cover from the air inlet to the turbocharger. Install the air cleaner element.
- Secure the access door.
- If necessary, reset the air cleaner service indicator.

Some applications use an air silencer that is wrapped in a washable soot filter. The soot filter helps prevent airborne dust and debris from entering the air inlet. As the soot filter becomes dirty, the air restriction increases. Replace the soot filter when the air restriction reaches
- Remove the dirty soot filter from the air silencer.
- Inspect the air silencer. Clean the air silencer, if necessary.
- Inspect a clean, dry soot filter for good condition. Install the soot filter.
The air cleaner element can be used up to six times. When the element is cleaned, check the filter material for rips or tears. Replace the element at least one time per year regardless of the number of times the element had been cleaned.
Use clean elements while dirty elements are being cleaned.
Do not clean the air cleaner elements by bumping or tapping. This could damage the seals. Do not use elements with damaged pleats, gaskets or seals. Damaged elements will allow dirt to pass through. Engine damage could result.
Visually inspect the elements before cleaning. Inspect the elements for damage to the seal, the gaskets, and the outer cover. Discard any damaged elements.
Two methods are used to clean air cleaner elements:
- Pressurized air
- Vacuum cleaning
Pressurized air can be used to clean elements that have not been cleaned more than two times. Pressurized air will not remove deposits of carbon and oil. Use filtered, dry air with a maximum pressure of
Note: When the elements are cleaned, always begin with the clean side (inside) in order to force dirt particles toward the dirty side (outside).
Aim the hose so that the air flows inside the element along the length of the filter to help prevent damage to the paper pleats. Do not aim the stream of air directly at the element. Dirt could be forced into the pleats.
Note: Refer to "Inspecting the Air Cleaner Elements".
Vacuum cleaning is a good method for cleaning elements which require daily cleaning because of a dry, dusty environment. Cleaning with pressurized air is recommended prior to vacuum cleaning. Vacuum cleaning will not remove deposits of carbon and oil.
Note: Refer to "Inspecting the Air Cleaner Elements".
Inspect the clean, dry element. Use a 60 W 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 necessary 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.
If an element that passes inspection will not be used immediately, store the element for future use.
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 Inhibiter (VCI) paper.
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:
- Date of cleaning
- Number of cleanings
Store the container in a dry location.
For detailed information on cleaning the air cleaner element, refer to Special Publication, SEBF8062, "Procedure to Inspect and Clean Air Filters".
