AIR CLEANER AND EXHAUST SYSTEM

REMOVAL

1. See Figure 1-6. Remove screw (1) and air cleaner cover

(2).

2. Remove three TORX screws (4) and bracket (5) from filter element (6).

3. Gently pull both rubber breather hoses (9) from the element. Remove filter element (6) and gasket (7).

4. Replace the filter element if damaged or if filter media cannot be adequately cleaned.

Do 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)

5. Gently pull the breather hoses from the breather bolts on the backplate (8).

Compressed air can pierce the skin and flying debris from compressed air could cause serious eye injury. Wear safety glasses when working with compressed air. Never use your hand to check for air leaks or to determine air flow rates. (00061a)

6.Clean filter element.
a. Wash the paper/wire mesh air filter element and breather hoses in lukewarm water with a mild detergent. Do not strike filter element on a hard surface to dislodge dirt.

b. Allow filter to either air dry or blow it dry, from the inside, with low pressure air. Do not use air cleaner filter oil on the Harley-Davidson paper/wire mesh air filter element.

c. Hold the filter element up to a strong light source. If light is uniformly visible through the element, it is sufficiently clean.

7. Inspect seal ring (3) on cover for cracks or tears. Verify that it seals tightly to backplate. Replace as required.

8. Inspect breather hoses for tears, cuts, holes or other damage. Replace as necessary.

NOTE

The breather hoses allow crankcase vapors to be directed into the air filter element. By providing effective recirculation of crankcase vapor, the hoses serve to eliminate the pollutants normally discharged from the crankcase. Air cleaner mounting without installation of the breather hoses, or with breather hoses that are not air tight, allows crankcase vapors to be vented into the atmosphere in violation of legal emissions standards. This will also negatively affect the engine's breather system as it will cause the umbrella valve to flutter.

9. Wipe inside of air cleaner cover and backplate with damp cloth to remove dust.
