Cleaning Primary Air Filter Elements

NOTICECaterpillar recommends certified air filter cleaning ser-vices available at participating Caterpillar dealers. TheCaterpillar cleaning process uses proven proceduresto assure consistent quality and suf ficient filter life.

Observe the following guidelines if you attempt toclean the filter element:

Do not tap or strike the filter element in order to re-move dust.

Do not wash the fi lter element.

Use low pr essure compressed air in order to removethe dust from the fi lter element. Air pressure must notexceed 207 kPa (30 psi). Direct the air flow up thepleats and down the pleats from the inside of the filter element. Take extreme care in order to avoid damageto the pleats.

Do not use air filters with damaged pleats, gaskets, or seals. Dirt entering the engine will cause damage toengine components.

When the primary air filter element is cleaned, checkfor rips or tears in the filter material. Replace the

primary air filter element after the primary air filter element has been cleaned six times. The primary air filter element should be replaced at least one timeper year. This replacement should be performedregardless of the number of cleanings.

NOTICEDo not clean the air filter 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 fi lter elements beforecleaning. Inspect the air fi lter elements for damageto the seal, the gaskets, and the outer cover. Discardany damaged air fi lter elements.

There are two common methods that are used toclean primary air fi lter elements:

• Pressurized air

• Vacuum cleaning

Pressurized Air

Pressurized air can be used to clean primary air filter elements that have not been cleaned more than twotimes. Pressurized air will not remove deposits of carbon and oil. Use fi ltered, dry air with a maximum

pressure of 207 kPa (30 psi).


Note: When the primary air filter 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 flows inside the elementalong the length of the fi lter in order to help preventdamage to the paper pleats. Do not aim the stream of air directly at the primary air filter element. Dirt couldbe forced further into the pleats.

Vacuum Cleaning

Vacuum cleaning is another method for cleaningprimary air filter 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.

Engine Air Filter Secondary Element - Replace

Inspecting the Primary Air Filter Elements


Inspect the clean, dry primary air filter element. Use

a 60 watt blue light in a dark room or in a similar facility. Place the blue light in the primary air filter element. Rotate the primary air fi lter element. Inspectthe primary air filter element for tears and/or holes.Inspect the primary air filter element for light that mayshow through the fi lter material. If it is necessary inorder to confirm the result, compare the primary air filter element to a new primary air fi lter element thathas the same part number.

Do not use a primary air fi lter element that has anytears and/or holes in the filter material. Do not usea primary air filter element with damaged pleats,gaskets or seals. Discard damaged primary air fi lter elements.

Storing Primary Air Filter Elements

If a primary air filter element that passes inspectionwill not be used, the primary air filter element canbe stored for future use.


Do not use paint, a waterproof cover, or plastic as aprotective covering for storage. An air flow restrictionmay result. To protect against dirt and damage, wrapthe primary air filter elements in Volatile CorrosionInhibited (VCI) paper.

Place the primary air filter element into a box for storage. For identification, mark the outside of thebox and mark the primary air fi lter element. Includethe following information:

• Date of cleaning

• Number of cleanings

Store the box in a dry location.

Improvements in the engine allowthis engine oil change interval. This new standard interval is notpermitted for other machines. Refer to the applicable Operationand Maintenance Manuals for the other machines.

(2) Normal conditions include these factors: Fuel sulfur below

0.3%, altitude below 1830 m (6000 ft), and good air fi lter andfuel fi lter maintenance. Normal conditions do not include highload factor, harsh operating cycles, or harsh environments.

(3) High load factors can shorten the service life of your engineoil. Continuous heavy load cycles and very little idle time resultin increased fuel consumption and oil contamination. Thesefactors deplete the oil additives more rapidly. If the averagefuel consumption of your machine exceeds 37.8 L (9.8 US gal)per hour, follow the “High Load Factor” recommendations inTable 183. To determine average fuel consumption, measureaverage fuel consumption for a period of 50 to 100 hours. If the application of the machine is changed, the average fuelconsumption may change.

(6) Use “Program B” below to determine an appropriate interval.

Adjustment of the Oil Change Interval

Note: Your Caterpillar dealer has additionalinformation on these programs.

Program A

Verification for an Oil Change Interval of 500 Hours

This program consists of three oil change intervals of 500 hours. Oil sampling and analysis is done at 250hours and 500 hours for each of the three intervalsfor a total of six oil samples. The analysis includesoil viscosity and infrared (IR) analysis of the oil. If all of the results are satisfactory, the 500 hour oil

change inter val is acceptable for the machine in thatapplication. Repeat Program A if you change theapplication of the machine.

If a sample does not pass the oil analysis, take oneof these actions:

• Shorten the oil change interval to 250 hours.

• Proceed to Program B.

• Change to a preferred oil type in Table 183.

Program B

Optimizing Oil Change Intervals

Begin with a 250 hour oil change interval. The oilchange intervals are adjusted by increments. Eachinterval is adjusted an additional 50 hours. Periodic oilsampling and analysis is done during each interval.The analysis includes oil viscosity and infrared (IR)analysis of the oil. Repeat Program B if you changethe application of the machine.

If an oil sample does not pass the analysis, shortenthe oil change interval, or change to a preferredmultigrade oil type in the listing above.

Hand Washing

Use a wet solution with no abrasive material thatcontains no solvents and no alcohol. Use a wetsolution with a “pH” value between 3 and 11. Usea soft brush, a rag, or a sponge in order to clean

the product identification fi lms. Avoid wearing downthe surface of the product identification films withunnecessary scrubbing. Ensure that the surface of the product identification films is flushed with cleanwater and allow the product identification films to air dry.

Power Washing

Power washing or washing with pressure may beused in order to clean product identification films.However, aggressive washing can damage theproduct identification films.

Excessive pressure during power washing candamage the product identification films by forcingwater underneath the product identificationfilms. Water lessens the adhesion of the productidentification fi lm to the product, allowing the productidentification film to lift or curl. These problems aremagnified by wind. These problems are critical for the perf orated fi lm on windows.

To avoid lifting of the edge or other damage to theproduct identification films, follow these importantsteps:

• Use a spray nozzle with a wide spray pattern.

• A maximum pressure of 83 bar (1200 psi)

• A maximum water temperature of 50° C (120° F)

• Hold the nozzle perpendicular to the productidentification film at a minimum distance of 305 mm(12 inch).

• Do not direct a stream of water at a sharp angle tothe edge of the product identification fi lm.
