TB 9-2300-378-14 2-3. Air Cleaner Inspection. a. Examine the housing and the base plate for hairline cracks. If you find cracks in the housing, report to organizational maintenance immediately so the air cleaner assembly can be replaced. Do not operate the tank until it is repaired. b. With the engine running, check to see that air exhaust can be felt at all four blower motor elbows (fig. 2-1). Notify organizational maintenance immediately if two are not working on the same air cleaner. Do not operate your tank. If air exhaust can be felt at only one blower motor elbow on each air cleaner, you may continue to operate. Notify organizational maintenance at first opportunity because the blower motors may be inoperative and require replacement. NOTE Not all air cleaners have air cleaner filter clog indicators. c. If your air cleaner has a filter clog indicator, take a reading as described in paragraph 2-4. Figure 2-1. Blower motor check. 2-7
