Refer to Maintenance Scheduling → Regular Service Intervals → Regular Service Intervals: 2009 FXDFSE Models. Inspect filter element at proper intervals and service as required. Under dusty conditions, inspect more often.
NOTICE
Install air filter before running engine. Failure to do so can draw debris into the engine and could result in engine damage. (00207a)
Domestic Models
See Figure 1. On domestic models, the high flow air cleaner has a cotton gauze filter element and water resistant rain sock. Slip the rain sock over the filter element under wet or rainy conditions. Use the following instructions to clean the high flow air cleaner.
NOTE
- The use of cleaning, drying or oiling methods or products other than those shown will damage the filter and void the manufacturer's warranty.
- K&N Air Filter Cleaner is available from a Harley-Davidson Dealer, either alone (1 qt/0.95 L sprayer bottle, Part Number 99883-88T) or a 12 fl oz/0.35 L sprayer bottle as part of the Filter Care Service Kit (Part Number 99850-92T).
- K&N Air Filter Oil is also available from a Harley-Davidson Dealer, either alone (12.25 oz/ 347 gram aerosol can, Part Number 99882-88T) or a 6.5 oz/ 184 gram aerosol can as part of the Filter Care Service Kit.
- DO NOT OVER-OIL THE AIR FILTER. Over-oiling may interfere with the proper performance of the engine and/ or certain engine components. If oil is still draining or dripping from the filter media twenty minutes after oiling, re-clean and re-oil the filter element.
| 1. | Loosen the hose clamp retaining the air filter element assembly to the air tube. Separate the element from the air tube. | |
| 2. | Tap the element to dislodge any loose dirt, then gently brush with a soft bristle brush. | |
| 3. | Spray air filter cleaner liberally onto the cotton filter media and let soak for ten minutes, OR roll or 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 naturally. 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 76 mm (3 in) away from the media, OR carefully use a squeeze bottle to deposit oil along each pleat, once only. Let the oil wick (absorb) into the filter media for twenty minutes before proceeding. | |
| 7. | After twenty minutes, inspect the filter media, and carefully apply oil to any remaining visible white spots on the filter media, and allow to absorb. | |
| 8. | Slip the air filter element onto the intake tube approximately 16 mm (⅝ in). Tighten the clamp around the filter element flange to 3.4–4.5 N·m (30–40 in-lbs). |
