Fleetguard 4936636 Crankcase Ventilation Filter Assembly

The Fleetguard CV52001 (Cummins 4936636) is a closed crankcase ventilation (CCV) filter assembly designed to separate oil mist and aerosol contaminants from blow-by gases before they re-enter the engine intake system. This coalescer-style filter protects the turbocharger, charge air cooler, and aftertreatment components from oil fouling and reduces hydrocarbon emissions. Constructed with high-efficiency synthetic glass fiber media, the filter achieves up to 99 percent filtration efficiency for aerosol particles. The spin-on canister design features a sealed housing with integrated mounting flange for direct installation on the Cummins 6.7L engine crankcase ventilation module. Service interval aligns with OEM recommendations of 67,500 miles or 1,500 hours under normal duty cycles. Cross-reference interchange includes Cummins 4936636, Mopar 68002433AB/AC/AA, Fleetguard CV52001/CV5200100, Dorman 904-418, and aftermarket numbers CV15010, WA11221, KPCV25001P1.
