Crankcase Filters

Crankcase ventilation (CCV) filters separate oil mist from engine blow-by gases. We list six:

  • Fleetguard CV50633: Cummins ISX and ISM
  • Fleetguard CV50626: Cummins ISX12 and X12
  • Fleetguard CV50628: replaces Cummins 5263190
  • Fleetguard CV52001: Cummins B6.7 and ISB 6.7
  • PACCAR 2299013PE: MX-13 CCV/OCV filter (Media B)
  • X002WK27ZN: aftermarket replacement for CV52001

A restricted CCV filter raises crankcase pressure, which can push oil past seals and gaskets, so replace it at the engine maker's service interval. These filters are engine-specific: match the number on the old element or the engine model. More filters are in filtration, Fleetguard and PACCAR.
