    Typical example

  1. Remove covers (1) from the air filter housings.



    Illustration 3g01387286

  1. Clean the inside of air filter housing (3) .

  1. Inspect the primary filter element. If the pleats, the gaskets or the seals are damaged, properly discard the primary filter element. Replace a damaged primary element with a clean primary filter element.


    NOTICE

    Do not clean the primary elements by bumping or tapping them. Do not use primary elements with damaged pleats, gaskets or seals. Engine damage can result.

    Make sure the cleaned primary elements are completely dry before installing them into the filter housing. Water remaining in the elements can cause false indications of contamination in S·O·S Analysis test results.


  1. If the primary filter element is not damaged, clean the primary filter element. The primary filter element can be cleaned by using the following methods:

    • Pressure air.

    • Pressure water.

    • Detergent washing.

    When you use pressure air, the maximum air pressure is 205 kPa (30 psi). When you use pressure water, the maximum water pressure is 280 kPa (40 psi).




    Illustration 5g00905242

  1. When you clean the inside pleats and the outside pleats, direct the air along the pleats or direct the water along the pleats.

    The primary filter element can be washed in a solution that consists of warm water and of nonsudsing household detergent. Fully rinse the pleats. Allow the primary filter element to air dry completely.

  1. Inspect the primary filter element after you clean the primary filter element. Do not use a primary filter element if the pleats, the gasket or the seals are damaged.

  1. Cover the clean primary filter element. Store the primary element in a clean, dry location.

    A primary filter element may be cleaned for a maximum of six times. Also replace the primary filter element if the primary filter element has been in service for one year.

  1. Install a clean primary filter element.

    Note: Make sure that the primary filter element is properly seated and sealed.




    Illustration 6g01921174

  1. Install covers (1) to the air filter housings as shown in Illustration 6.

    Note: If the air filter restriction indicator remains on after starting the engine, or the exhaust smoke is still black after installing a clean primary element, install a new primary filter element. If the indicator remains on after installing a new primary filter element, replace the secondary filter element.

ReferenceFor the correct procedure to replace the secondary filter element, refer to the Operation and Maintenance Manual, "Engine Air Filter Secondary Element - Replace".
