All engines are equipped with dry type air cleaners with replaceable air filter elements. The Positive Crankcase Ventilation (PCV) system air filter element on gasoline engines is also found in the air filter housing (usually mounted on the inside of the housing rim). Both of these filter elements should be replaced at 30,000 mile or 1 1 / 2 year intervals on all models, except in extremely dusty or smoggy conditions where replacement should be much more frequent.
REMOVAL & INSTALLATION
- Remove the wingnut(s) from the top of the air cleaner assembly and lay it aside.
- Remove the air cleaner cover and gently lift the air cleaner element out of the housing without knocking any dirt into the carburetor.
- Pull the PCV filter out of the retainer.
- Wipe the inside of the air cleaner housing with a paper towel or clean rag.
- Clean the inside of the PCV filter retainer and install a new PCV filter element.
- Install a new air cleaner element.
- Replace the air cleaner cover and install the wing nut(s).
