Never run the engine without an air cleaner element installed. Never run the engine with a damaged air cleaner element. Do not use air cleaner elements with damaged pleats, gaskets or seals. Dirt entering the engine causes premature wear and damage to engine components. Air cleaner elements help to prevent airborne debris from entering the air inlet. |

|
Never service the air cleaner element with the engine running since this will allow dirt to enter the engine. |
Servicing the Air Cleaner Elements
If the air cleaner element becomes plugged, the air can split the material of the air cleaner element. Unfiltered air will drastically accelerate internal engine wear. Your Caterpillar dealer has the proper air cleaner elements for your application. Consult your Caterpillar dealer for the correct air cleaner element.
- Check the precleaner (if equipped) daily for accumulation of dirt and debris. Remove any dirt and debris, as needed.
- Operating conditions (dust, dirt, and debris) may require more frequent service of the air cleaner element.
- The air cleaner element may be cleaned up to six times if the element has been properly cleaned and inspected.
- The air cleaner element should be replaced at least one time per year. This replacement should be performed regardless of the number of cleanings.
Replace the dirty paper air cleaner elements with clean air cleaner elements. Before installation, check the air cleaner elements thoroughly for tears and/or holes in the filter material. Inspect the gasket or the seal of the air cleaner element for damage. Maintain a supply of suitable air cleaner elements for replacement purposes.
The dual element air cleaner contains a primary air cleaner element and a secondary air cleaner element. The primary air cleaner element can be used up to six times if the element has been properly cleaned and inspected. The primary air cleaner element should be replaced at least one time per year. This replacement should be performed regardless of the number of cleanings.
The secondary air cleaner element is not serviceable or washable. The secondary air cleaner element should be removed and discarded for every three cleanings of the primary air cleaner element. When the engine is operating in environments that are dusty or dirty, air cleaner elements may require more frequent replacement.

- Remove the cover. Remove the primary air cleaner element.
- The secondary air cleaner element should be removed and discarded for every three cleanings of the primary air cleaner element.
Note: Refer to "Cleaning the Primary Air Cleaner Elements".
- Cover the air inlet to the turbocharger with tape in order to keep out dirt.
- Clean the inside of the air cleaner cover and body with a clean, dry cloth.
- Remove the tape from the air inlet of the turbocharger. Install the secondary air cleaner element. Install a primary air cleaner element that is new or cleaned.
- Install the air cleaner cover.
- Reset the air cleaner service indicator.
Cleaning the Primary Air Cleaner Elements
Caterpillar does not recommend the cleaning of air filter elements, since there is not a relatively feasible and reliable method of inspecting air filter elements for damage. A damaged air filter element can allow dirt to pass through, thereby resulting in reduced efficiency.
Cleaning the air filter element will result in a progressive reduction from the original filter capacity each time the filter is cleaned. However, if the owner insists on cleaning primary air filter elements to extend filter life, the following instructions may help to minimize the risks.
Do not clean the air filter elements by bumping or tapping as this can cause damage. Do not use air filter elements with damaged pleats, gaskets, or seals. Discard damaged air filter elements.
Do not use solvents or water to wash the air filter element.
When attempting to clean the primary air filter element, use a maximum gauged air pressure of
The engine air filter secondary (safety) element should never be cleaned and should be replaced every third primary air filter element change, or as required.
Never attempt to replace a filter element while the engine is running.

Due to the lack of a feasible and reliable filter element inspection procedure, the customer is encouraged to closely monitor the engine S·O·S (scheduled oil sampling) as the best means to detect dust ingestion into the engine. Refer to the Operation and Maintenance Manual for more details. |
