TheCaterpillar cleaning process uses proven proceduresto assure consistent quality and sufcient lter life.Observe the following guidelines if you attempt toclean the lter element:Do not tap or strike the lter element in order to re-move dust.Do not wash the lter element.Use low pressure compressed air in order to removethe dust from the lter element. Air pressure must notexceed 207 kPa (30 psi). Direct the air ow up thepleats and down the pleats from the inside of the lterelement. Take extreme care in order to avoid damageto the pleats.Do not use air lters with damaged pleats, gaskets, orseals. Dirt entering the engine will cause damage toengine components.The primary air lter element can be used up to sixtimes if the element is properly cleaned and if theelement is properly inspected. When the primaryair lter element is cleaned, check for rips or tearsin the lter material. The primary air lter elementshould be replaced at least one time per year. Thisreplacement should be performed regardless of thenumber of cleanings.NOTICEDo not clean the air lter elements by bumping or tap-ping. This could damage the seals. Do not use ele-ments with damaged pleats, gaskets, or seals. Dam-aged elements will allow dirt to pass through. Enginedamage could result.Visually inspect the primary air lter elements beforecleaning. Inspect the air lter elements for damageto the seal, the gaskets, and the outer cover. Discardany damaged air lter elements.There are two common methods that are used toclean primary air lter elements: Pressurized air Vacuum cleaningPressurized AirPressurized air can be used to clean primary air lterelements that have not been cleaned more than twotimes. Pressurized air will not remove deposits ofcarbon and oil. Use ltered, dry air with a maximumpressure of 207 kPa (30 psi).g00281692Illustration 100Note: When the primary air lter elements arecleaned, 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 ows inside the elementalong the length of the lter in order to help preventdamage to the paper pleats. Do not aim the stream ofair directly at the primary air lter element. Dirt couldbe forced further into the pleats.Vacuum CleaningVacuum cleaning is another method for cleaningprimary air lter elements which require daily cleaningbecause of a dry, dusty environment. Cleaning withpressurized air is recommended prior to vacuumcleaning. Vacuum cleaning will not remove depositsof carbon and oil.KEBU7519-08 83Maintenance SectionEngine Air Filter Secondary Element - ReplaceInspecting the Primary Air FilterElementsg00281693Illustration 101Inspect the clean, dry primary air lter element. Usea 60 watt blue light in a dark room or in a similarfacility. Place the blue light in the primary air lterelement. Rotate the primary air lter element. Inspectthe primary air lter element for tears and/or holes.Inspect the primary air lter element for light that mayshow through the lter material. If it is necessary inorder to conrm the result, compare the primary airlter element to a new primary air lter element thathas the same part number.Do not use a primary air lter element that has anytears and/or holes in the lter material. Do not usea primary air lter element with damaged pleats,gaskets or seals. Discard damaged primary air lterelements.Storing Primary Air Filter ElementsIf a primary air lter element that passes inspectionwill not be used, the primary air lter element canbe stored for future use.g00281694Illustration 102Do not use paint, a waterproof cover, or plastic as aprotective covering for storage. An airow restrictionmay result. To protect against dirt and damage, wrapthe primary air lter elements in Volatile CorrosionInhibited (VCI) paper.Place the primary air lter element into a box forstorage.
