Applications
The AF25667 and AF26114 combination is referenced for selected Komatsu construction machinery, including PC200-8 and PC220-8 excavators and PC290-8 excavators.
The corresponding Komatsu reference components are 600-185-4110 for the primary element and 600-185-4120 for the secondary safety element. The combined air filter kit is referenced as 600-185-4100.
Additional published applications include selected Freightliner FL60, FL70, FL80, M2 and Cascadia commercial trucks with compatible air cleaner assemblies.
Equipment compatibility depends on machine serial number, engine configuration, production year and air cleaner housing. Both elements must match the original installation requirements.
