Maintenance Level Unit 3-13.   AIR CLEANER FILTER ELEMENT SERVICING TM 9-2320-387-24-1 3-24 Change 1 WARNING •  Improper cleaning methods and use of unauthorized cleaning liquids can injure personnel and cause damage to equipment. Do not use anything other than compressed air, water, and detergent to clean elements. •  If NBC contamination is suspected, consult NBC officer or NBC NCO for appropriate handling instructions. NOTE The vehicle air cleaner may be configured with either a ring clamp or over-center clamp. 1. Loosen screw (8), or unlatch and remove clamp (1), cover (2), and gasket (3) from air cleaner assembly (6). CAUTION Cover housing opening with screen or rag to prevent contaminants from entering air intake system and damaging engine. 2. Remove nut and washer assembly (7) and filter element (4) from stud (5) of air cleaner assembly (6). 1. Check gasket (3) for dents, tears, rips, and other damage. Ensure gasket has not taken a set. Ensure there are no hard dirt ridges on sealing surfaces. 2. Inspect filter element (4) for holes and tears by looking through element toward a bright light. If pinpoints of light shine through, replace element. Holes that are large enough to let light through are large enough to let contaminants through. Another way to check for leaks or damage is to look for uneven dirt patterns. Ensure there is no rust or flaking paint on metal parts of filter. If the filter has already been cleaned three times, or if damaged, replace filter element (4). 3. Check air cleaner assembly (6) for holes, dents, rust, or any other damage that will interfere with proper sealing and allow unfiltered air to enter and destroy engine. CAUTION Do not strike ends of filter element on hard surface, or damage to filter element may result. Remove dust or sand from filter element (4) by holding it so neither end faces ground, and gently tap around filter element (4). c.   Emergency Cleaning b.   Inspection a.   Removal
