2.Remove the element cover nut, element cover, and paper element with precleaner.
3.Remove the precleaner (if so equipped) from the paper element.

5.When servicing the air cleaner, check the air cleaner base. Make sure it is secured and not bent or damaged. Also check the element cover for damage or improper fit. Replace all damaged air cleaner components.
NOTE: If any loose dirt or debris fell on the air cleaner base when the element was removed, carefully remove it and wipe the base clean. Be careful that none of it drops into the intake throat. Check the condition of the rubber seal on the air cleaner stud. If the condition is questionable in any way, replace it with the new seal packaged with the replacement element.
