Engine - Air Cleaner Section 110-0050 cleaned twice a year. Do not apply heat in any form to air cleaner body (1). 2. Remove primary element (2) from air cleaner body (1). 1. Release latches (5) on cover assembly (4) and remove cover assembly from air cleaner body (1). 3. Using a damp cloth and a suitable solvent, wipe out all excess dust from air cleaner body (1) and allow to dry. 2. Remove primary element (2) and safety element (3) from air cleaner body (1). 4. If the major contaminant on primary element (2) is light dust, direct a jet of compressed air, not exceeding 6.9 bar (100 lbf/in 2 ), against the pleats of the element.
The air jet should be directed in the opposite direction of normal operating air flow. Move the air jet up and down the pleats, holding the air nozzle 25 mm (1.0 in) away from the pleats, to prevent rupturing the element with either the nozzle or air jet. 3. Slacken clamps (9, Fig. 3) and disconnect hump hose (8, Fig. 3) from air cleaner body (1). 4. Remove locknuts (5, Fig. 3), hardened washers (3, Fig. 3) and bolts (4, Fig. 3) securing the air cleaner assembly to the platform. 5. Remove the air cleaner assembly from the platform for cleaning. 5. In cases where the dust cake on primary element (2) contains oil or carbon, air will not clean effectively.
Using manufacturers recommended solution and warm water, not exceeding 48° C (120° F), soak primary element (2) for fifteen minutes. Element should be gently agitated to assist cleaning process. 6. Open clamps (6) and remove from air cleaner body (1). Open clamp on cap assembly (7) and remove cap assembly from air cleaner body (1). 7. Blank off air cleaner body (1) outlets with tape or cardboard. Reach inside body with a compressed air nozzle or brush and remove dust from the body. Note: It is possible to modify an old agitator type washing machine for primary element (2) cleaning. Do not soak or agitate primary element (2) in the solution for more than fifteen minutes.
Prolonged exposure softens vertical seams in the element. 8. Remove all loose dust from air cleaner body (1) and remove tape or cardboard from body outlets. 6. Rinse washed element thoroughly with a low pressure stream of water, not exceeding 0.7 bar (10 lbf/in 2 ), opposite from the normal air flow, until rinse water runs clear. Note: Assembly and installation of the air cleaner assembly is the reverse of disassembly and removal. 7. Air dry primary element (2) thoroughly before returning it to service. Drying is a slow process which may be hastened by exposing element to slowly circulating heated air. Heated air temperature should not exceed 46 o C (115 o F).
Drying time can be reduced to about three hours with heated air. DO NOT use a light bulb for drying. DO NOT use compressed air on a wet element. Primary Element Numbers in parentheses refer to Fig. 1. Although a paper primary element (2) is used, it is possible to clean it so that it can be reused. The number of times one element can be reused depends on the type of dirt on the element and the care exercised in cleaning. Note: Replace paper elements after six cleanings or two years in service, whichever comes first. Mark each cleaned element to show total cleanings to date.
The life of a properly cleaned element will be approximately as long as that of a new element for the first one or two cleanings. After that, the life of the element will gradually decrease with each cleaning; however, it should perform satisfactorily through approximately six cleanings, providing it does not rupture. 8. After primary element (2) is thoroughly dried, inspect for damage or ruptures, especially close to the end caps. To detect paper ruptures, place a bright light bulb inside the element and rotate element slowly. Inspection of element on the outside will disclose any holes where concentrated light shines through.
Even the smallest hole will pass dust to the engine and may result in costly engine repairs. Visually determine the condition of primary element (2) and choose either the compressed air or washing method. 1. Release latches (5) on cover assembly (4) and remove cover assembly from air cleaner body (1). 9. Install primary element (2) in air cleaner body (1). 3 SM 1572 12-98
