SERVICE BULLETINSB 2-220-001JUNE, 2007REPAIR PROCEDURESTEP 1: Determine the correct replacement filter• Identify the replacement part number for the airfi lter element. The replacement part number isshown on a decal, applied to the air fi lter assembly(Figure 1).NOTICEFailure to replace the air filter element using thecorrect part number can result in an inadequateseal between the filter element and the air filterhousing. An inadequate seal will allow unfilteredair to enter the engine which will causeaccelerated wear and damage to the engine.NOTE:The part number for the air fi lter elementmay be different than the part numbershown in Figure 1.Air filter elementpart numberNOTICEIf a genuine Donaldson filter element is notused as replacement, it is crucial that any othermanufacturer’s air filter element is accuratelycross-referenced and verified to be the correctservice replacement part.Engine failures which are the result of unfilteredair entering the engine through an incorrectlyinstalled or incorrectly designed replacement airfilter element should be directed to the specificair filter element’s manufacturer, or to the agentdesignated by the filter’s manufacturer.Radial SealSee owner’s manual for detailed service instructions1.

SERVICE BULLETINSB 2-220-001JUNE, 2007STEP 2: Remove the air filter• Unfasten or unlatch the service cover. Becausethe fi lter element fi ts tightly over the outlet tubeto create the critical seal, there will be some initialresistance in breaking the seal.• Gently move the end of the fi lter element back andforth to break the seal then rotate while pullingstraight out (Figure 2).• Make sure that all contaminant is removed beforethe new fi lter element is inserted. Dirt accidentlytransferred to the inside of the outlet tube willreach the engine and cause accelerated enginewear. Be careful not to damage the sealing areaon the tube.NOTE:If your air fi lter assembly is equipped with aVacuator valve (Figure 4), visually check andsqueeze the valve to make sure it is fl exibleand not inverted, damaged or plugged.Figure 2• Avoid knocking the fi lter element against thehousing.NOTE:If the air fi lter assembly is equipped witha safety fi lter, replace it with every thirdprimary fi lter change. Remove the safetyfi lter in the same manner as the primaryfi lter. Cover the air cleaner outlet tube toprevent any unfi ltered contaminant fromdropping into the engine.STEP 3: Clean both surfaces of the outlet tubeand check the Vacuator valve• Use a clean cloth to wipe the fi lter sealing surfaceand the inside of the outlet tube (Figure 3).Contaminant on the sealing surface could hinderan effective seal and cause leakage.Figure 4STEP 4: Inspect the old air filter for evidence ofair leaks• Visually inspect the old fi lter element for any signsof leaks (Figure 5). A streak of dust on the cleanside of the fi lter is a clear indicator of an air leak.Figure 5• Correct the cause of any air leaks before installingthe new fi lter element.Figure 3Wipe the outeredge of the outlettube clean.Wipe the insideedge of the outlettube clean.Autocar, LLC551 South Washington StreetP.O.

SERVICE BULLETINSB 2-220-001JUNE, 2007STEP 5: Inspect the new air filter for damage• Inspect the new fi lter element carefully, payingattention to the inside of the open end, which is thesealing area (Figure 6).• NEVER install a damaged fi lter element.NOTE:Figure 6A new radial seal fi lter may have adry lubricant applied to the seal to aidinstallation.STEP 6: Insert the new radial seal filter properly• If the vehicle is equipped with a safety fi lter, itshould be seated into position before installing theprimary fi lter element.• Insert the new fi lter element carefully. Seat thefi lter by hand, making certain it is bottomed-out inthe air cleaner housing (Figure 7).Figure 7NOTICENever use the service cover to push the filterelement into place. Using the cover to pushthe filter in could damage the air filter housing,cover fasteners, and will void the air filterassembly warranty.• No cover pressure is required to hold the sealbetwen the fi lter element and the fi lter housing.• If the service cover contacts the fi lter elementbefore the cover is seated, remove the cover andpush the fi lter (by hand) deeper into the air cleanerhousing. The cover should then install without anyadditional force.• Fasten the service cover.STEP 7: Check air intake piping for a tight fit• Make sure that all mounting bands, clamps, bolts,and connections in the entire air intake system aresecure.• Check for holes in the air intake piping and repairif needed.Any leaks in the intake piping will allow unfi lteredair directly into the engine.Please direct all questions regarding this servicebulletin to: info@autocartruck.com or call the servicehotline at 877.973.3486, extension 6062.• The critical sealing collar will stretch slightly,adjusting itself to distribute the sealing pressureevenly.• To complete a tight seal, apply pressure by handat the outer rim of the fi lter element, not the fl exiblecenter.Avoid pushing on the center of the urethane endcap.4 of 4AC-SB-256-0706-P152Autocar, LLC551 South Washington StreetP.O.
