PRIMARY AND SECONDARY FILTER ELEMENTS REPLACEMENT - CONTINUED
CLEANING AND INSPECTION
Check sealing surfaces on filter elements for dirt on the "clean" side. If this is evident, problem may be a damaged filter
element, incorrect element fit or the need for cleaning and/or repair of gasketed surfaces.
Compressed air used for cleaning purposes must not exceed 30 psi (207 kPa). DO NOT direct compressed
air against human skin. Make sure air stream is directed away from user and other personnel in the area.
Wear protective goggles or face shield. Failure to follow this warning may cause injury to personnel.
To prevent damage, DO NOT clean primary filter element by bumping or tapping.
Use a light inside primary filter element to inspect filter for tears, holes or other damage before and after
each cleaning process.
Discard primary filter element if any damage is evident.
Direct compressed air inside primary filter element, along length of filter pleats.
Direct compressed air outside primary filter element, along length of filter pleats.
Repeat step 2.
Manufacturer's specifications call for replacement of primary filter element after six cleanings and replace-
ment of secondary filter after three cleanings.
Clean and inspect all parts in accordance with WP 0020 00.
Ensure no gasket material remains on interior of air cleaner canister. If material remains, a poor seal will
allow dirty air into engine.
Install new gasket (6) and secondary filter element (7) into air cleaner (2).
Install six nuts (5). Tighten to 27 lb-ft (37 Nm).
Install primary filter element (8) in air cleaner (2).
