• Remove hardened dirt ridges wherever filter gaskets contact the cleaner housing.

• Clean the gasket sealing surfaces of the housing. An improper gasket seal is one of the most common causes

of engine contamination.

• Wipe every surface clean with a clean, water-dampened cloth.

• Check the housing visually to make sure it is clean before putting in a new filter element.

9. Check for uneven dirt patterns on your old element. Your old element is a valuable clue to potential dust leakage

or gasket sealing problems. A pattern on the element clean side is a sign that the old element was NOT firmly
sealed or that a dust leak exists.

• Press on the fresh gasket to see if it springs back.

• Check the gasket for correct sizing. On a radial seal element the gasket surface is the inside diameter of the

open end cap.

• Make sure the gasket is seating evenly.

If the gasket is not forming a perfect seal, you will NOT

have protection.

• Ensure the sealing surface in the housing is clean, and the filter element is the correct model number. It may

be too short for the housing.

• Identify and rectify the cause of any leaks before replacing the filter element.

10. If required, also change the secondary filter. Refer to

Installing Primary Air Filter

NOTE:
If replacing air filter, refer to

1. Insert new primary filter element (A) into canister over

secondary element, and push into place, ensuring that
element is firmly seated in canister.
