MAINTENANCE AND SERVICING
7. Clean the inside of the canister housing and end cap
carefully. Dirt left in the air cleaner housing may be
harmful to your engine.
• Remove hardened dirt ridges wherever fi lter 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 it visually to make sure it is clean before
putting in a new element.
8. 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
fi rmly 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 fi lter 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 fi lter element.
9. If required, also change the secondary fi lter. Refer
