Never service the air cleaner element with the engine running since this will allow dirt to enter the engine.
Servicing the Air Cleaner Elements
If the air cleaner element becomes plugged, the air can split the material of the air cleaner element. Unfiltered air will drastically accelerate internal engine wear. Your Cat dealer has the proper air cleaner elements for your application. Consult your Cat dealer for the correct air cleaner element.Locomotives can be fitted with a clean room of filtered air. Engine combustion air is pulled from this clean room.
Operating conditions (dust, dirt, and debris) may require more frequent service of the air cleaner element.
The air cleaner element may be cleaned up to three times if the element is properly cleaned and inspected.
The air cleaner element should be replaced at least one time per year. This replacement should be performed regardless of the number of cleanings.Replace the dirty paper air cleaner elements with clean air cleaner elements. Before installation, the air cleaner elements shall 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.

Caterpillar recommends certified air filter cleaning services that are available at Caterpillar dealers. The Caterpillar cleaning process uses proven procedures to assure consistent quality and sufficient filter life.Observe the following guidelines if you attempt to clean the filter element:Do not tap or strike the filter element in order to remove dust.Do not wash the filter element.Use low pressure compressed air in order to remove the dust from the filter element. Air pressure must not exceed 620 kPa (90 psi). Direct the air flow into the outlet end of the filter element, keeping the nozzle at least 50 mm (2 inches) away from the outlet face of the filter element.Do not use air filters with damaged pleats, gaskets, or seals. Dirt entering the engine will cause damage to engine components.
The air cleaner element can be used up to three times if the element is properly cleaned and inspected. When the air cleaner element is cleaned, check for rips or tears in the filter material. The air cleaner element should be replaced at least one time per year. This replacement should be performed regardless of the number of cleanings.Use clean air cleaner 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 air cleaner elements before cleaning. Inspect the air cleaner elements for damage to the seal, the gaskets, and the outer cover. Discard any damaged air cleaner elements.Pressurized Air
Pressurized air can be used to clean air cleaner elements up to three times. Pressurized air will not remove deposits of carbon and oil. Use filtered, dry air with a maximum pressure of 620 kPa (90 psi). Keep the air nozzle at least 50 mm (2 inch) away from the face of the filter element.Note: When the air cleaner elements are cleaned, always apply air pressure to the inside of the filter element.Note: Refer to "Inspecting the Air Cleaner Elements".Inspecting the Air Cleaner Elements
Inspect the clean, dry air cleaner element. Do not use an air cleaner element that has any tears and/or holes in the filter material. Do not use an air cleaner element with damaged pleats, gaskets, or seals. Discard damaged air cleaner elements.Storing Air Cleaner Elements
If an air cleaner element that passes inspection will not be used, the air cleaner element can be stored for future use.
Illustration 2 g00281694Do not use paint, a waterproof cover, or plastic as a protective covering for storage. An air flow restriction may result. To protect against dirt and damage, wrap the air cleaner elements in Volatile Corrosion Inhibited (VCI) paper.Place the air cleaner element into a box for storage. For identification, mark the outside of the box and mark the air cleaner element. Include the following information:
Date of cleaning
Number of cleaningsStore the box in a dry location.
