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 by-passing 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.When equipped with a dry-type air cleaner, a service indicator similar to the one shown is available.The air cleaner service 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 INDICATOR (OPTIONAL)Excessive 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 FILTER ELEMENT: Every 10,000 miles, in average operating conditions, remove the filter element for inspection and cleaning. This period may be extended in clean atmosphere and can only be determined by experience.1. To remove the filter element, loosen the wing nut, remove the end cover and the filter element.2. Inspect the element and if it is damaged, install a new element.3. Remove any dirt which has accumulated on the bottom of the case and clean the filter element using one of the methods covered in the topic, FILTER ELEMENT CLEANING.
DRY TYPE AIR CLEANER4. Install the filter element and cover. When installing the filter element, the closed end of the element must be installed against the cover. Fasten the cover securely.Restriction Of Air Inlet And Exhaust
If an air inlet restriction is suspected in the piping or air filter element, check with a differential pressure gauge or manometer. Remove the air cleaner service indicator and connect differential pressure gauge or manometer in the service indicator connection. The air inlet piping or air cleaner should not restrict air flow more than 30 inches (762 mm) of water difference in pressure.
CHECKING AIR INLET FOR RESTRICTIONRestriction of the exhaust system (back pressure) is measured with a differential pressure gauge or manometer. This pressure difference is measured between the turbocharger outlet and ambient air and should be no more than 20 inches (645 mm) of water. An exhaust pressure tap is provided in the turbocharger outlet elbow. This check should be performed with the engine at operating temperature and developing full rated power.
CHECKING EXHAUST BACK PRESSUREFilter Element Cleaning: (Caterpillar Dry-type Filter Elements Only - If Other Manufacturer's Air Cleaner Is Used Refer To Their Recommendations)
Filter elements can be cleaned several times before replacing; however, close inspection of the element should be made when reinstalling a cleaned element.The ends of a filter element will be damaged by bumping or tapping. Bent and/or dented ends cannot seal properly and may allow unfiltered air to enter the engine cylinders and cause premature engine wear.Clean the filter element using one of the following methods:CLEANING WITH PRESSURE AIR: Using clean, dry air, at a pressure not to exceed 30 PSI (2 kg/cm2), proceed as follows:Hold the air nozzle at least one inch from the element and direct air at an angle against the inside (engine side) of the element to loosen any imbedded dirt. Best results can be obtained by moving the air hose so that air is directed at an angle along the complete length of each pleat.Blow off loose dirt by directing air against the outside of the element. Repeat this procedure until the element is clean. Make certain that no dirt is inside the element.
CLEANING ELEMENT WITH AIRCLEANING WITH WATER: Using clean water, at a pressure not to exceed 40 PSI, proceed as follows:Direct water at an angle against the inside (engine side) of the element to loosen any imbedded dirt. Best results can be obtained by using a water hose without a nozzle and moving it so that water is directed at an angle along the complete length of each pleat. Wash off loose dirt by directing water against the outside of the element. Repeat this procedure until the element is clean. Make certain that no dirt is on the engine side of the element, and thoroughly dry the element before installing it.
CLEANING ELEMENT WITH WATERCLEANING WITH DETERGENT: Some oily and/or sooty deposits can be removed by washing the element in a solution of warm water and a good household non-sudsing detergent. Rinse with clean water and thoroughly dry the element before installing it.
WASHING ELEMENT WITH DETERGENTINSPECTING ELEMENT:1. Hold a lighted electric bulb inside the dried element and carefully inspect the element for tiny, pinpoints of light. Any light showing indicates a pleat has ruptured and will tear with further use. Discard the element.2. Wrap usable elements in sealed plastic bags.3. Store the wrapped element in a dry, clean place.
INSPECTING ELEMENTWhen equipped with oil bath type air cleaners, accumulation of dirt and/or oil in the air cleaner outlet pipe is an indication the air cleaner is
