Air Cleaners (Caterpillar Dry-type Air Cleaners Only)
Regular service intervals, along with close visual inspection of the air cleaner, are necessary for proper cleaning of the engine inlet air. The service interval will vary with the weather and working conditions. Where dust conditions are severe, it will be necessary to service the air cleaner frequently. In damp weather and other conditions of little or no dust, the service interval can be extended.To extend the service life of the element, the exhaust and air cleaner inlet pipes should be arranged so that exhaust and/or oil fumes do not enter the engine air cleaner.Visual inspection of the gaskets and seals is important in keeping dust from bypassing the air cleaner. Any dirt allowed to enter, accelerates wear throughout the engine. If the condition of any of the replaceable seals and gaskets is questionable, replace them. If the sealing ends of the filter element or the element pleats are damaged, replace the element.Extra filter elements should be kept on hand for replacement or for use in the air cleaner while the element that was removed is being cleaned.The air service cleaner indicator is connected to the air inlet pipe between the air cleaner and the turbocharger. It contains a red marked piston, which gradually rises with restriction to the air flow. When the entire piston is visible it will lock in this position. This indicates a need for air cleaner service. The piston will remain in this position whether or not the engine is running. After servicing the air cleaner, reset the piston by depressing the plunger in the bottom of the indicator.
AIR CLEANER SERVICE INDICATORExcessive engine exhaust smoke and/or loss of power may indicate the need for servicing the air cleaner. Never service the air cleaner while the engine is running.Single Stage Air Cleaner

1. Remove the air cleaner cover and element. 2. Cover the air inlet opening to prevent foreign objects from entering the engine.3. Clean the inside of the air cleaner cover and the air cleaner body. 4. Inspect the replacement element for damage and cleanliness. Have a replacement element on hand to install and use while cleaning the dirty element. This will save you down time.5. Remove the covering from the air inlet opening.6. Install the element.

Cleaning Elements With Air
1. Use clean, dry air-30 PSI (2 kg/cm2) maximum. Hold the nozzle at least one inch from the element and at a slight angle.
When using pressure air, wear safety glasses and protective clothing. Use no more than 30 PSI (2 kg/cm2) pressure.
2. Direct the air stream along the complete length of each pleat on
