Cleaning Filter Element
NOTE
- Do not strike filter element on a hard surface to dislodge dirt.
- Do not use air cleaner filter oil on the Harley-Davidson paper/wire mesh or synthetic air filter element.
WARNINGDo not use gasoline or solvents to clean filter element. Flammable cleaning agents can cause an intake system fire, which could result in death or serious injury. (00101a)
| 1. | Clean filter element. a. Wash the filter element and breather tubes in lukewarm water with a mild detergent. b. Synthetic element: Rinse filter element with clean water. The filter element is sufficiently clean when water running from the filter element appears clear. c. Allow filter element to air dry or use low-pressure compressed air from the inside. d. Paper/wire mesh element: Hold the filter element up to a strong light source. The element is sufficiently clean when light is uniformly visible through the media. e. Replace the filter element if damaged or if filter media cannot be adequately cleaned. |
Rain Sock
If equipped with oval air cleaner: See Figure 2. In wet or rainy conditions, because the filter element is exposed, water can enter the engine. When parked, water can cause internal engine corrosion or damage. When running, water can cause the engine to misfire. In wet or rainy conditions, install the rain sock (6) over the air cleaner assembly to minimize water intrusion.
Installation
Standard air cleaner
NOTE
Air cleaner mounting without installation of the breather tubes allows crankcase vapors to vent into the atmosphere. This violates emissions regulations.
