Air Cleaner Element Maintenance
When servicing the air cleaner, apply LOCTITE 243 MEDIUM STRENGTH THREADLOCKER AND SEALANT (BLUE) (99642-97) to the threads of all fasteners.
  1. Remove the air cleaner cover center screw.
  2. Tap the element to dislodge any loose dirt. Gently brush with a soft bristle brush.
  3. Spray air filter cleaner liberally onto the cotton filter media. Let soak for ten minutes OR roll and soak the cotton filter media in a shallow pan of air filter cleaner. Remove immediately, and let soak for ten minutes.
  4. Rinse off the filter media (flowing from the clean side to the dirty side), with low-pressure tap water.
  5. After rinsing, shake off all excess water, and let the filter media air dry. DO NOT use compressed air or a heat gun to speed drying.
  6. After the filter media is completely dry. EITHER spray air filter oil along each pleat, once only, holding the spray nozzle approximately 8 cm (3 in) away from the media, OR carefully use a squeeze bottle to deposit oil along each pleat, once only. Let the oil absorb into the filter media for 20 minutes before proceeding. After 20 minutes, inspect the filter media. Carefully apply oil to any remaining visible white spots on the filter media. Allow to absorb.
