PISTON 1U4617 - Caterpillar

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.
Note: Use of a platform may be necessary to reach the air cleaner element.Replace the air cleaner when the air cleaner reaches the maximum air filter restriction to maintain engine performance. The maximum air filter restriction levels are stated below:
Table 1
Maximum Air Filter Restrictions
Engine Restriction
G3512H 2.5 kPa (10 inch of H2O)
G3516H 2.5 kPa (10 inch of H2O)
G3520H 3.6 kPa (14.4 inch of H2O) Servicing the Air Cleaner Elements
Note: If the air cleaner is not manufactured by Caterpillar, follow the instructions that are provided by the OEM of the air cleaner.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 Cat dealer has the proper air cleaner elements for your application. Consult your Cat 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.Replace the dirty paper air cleaner elements with clean air cleaner elements. Before installation, thoroughly inspect the air cleaner elements 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.
Remove the air cleaner cover. Remove the air cleaner element.
Cover the air inlet to the turbocharger with tape to keep out dirt.
Clean inside the air cleaner cover and body with a clean, dry cloth.
Remove the tape for the air inlet to the turbocharger. Install an air cleaner element that is new or cleaned.
Install the air cleaner cover.Inspecting Air Cleaner Elements
Illustration 1 g00281693Inspect the clean, dry air cleaner element. Use a 60 W blue light in a dark room or in a similar facility. Place the blue light in the element. Rotate the element. Inspect the element for tears and/or holes. Inspect the element for light that may show through the filter material. If necessary, to confirm the result, compare the element to a new element that has the same part number.Do not use an element that has any tears and/or holes in the filter material. Do not use an element with damaged pleats, gaskets, or seals. Discard damaged elements.Storing Air Cleaner Elements
If an element that passes inspection will not be used, the element can be stored for future use.
Illustration 2 g00281694Do not use paint, a waterproof cover, or plastic as a protective covering for storage. Restricted air flow may result. To protect against dirt and damage, wrap the elements in Volatile Corrosion Inhibited (VCI) paper.Place the element into
