The NEXIQ Aftertreatment Service Kit is used as part of a cleaning routine to remove particulates and soot that impede or obstruct the honeycomb filter within the front face of the Diesel Oxidation Catalyst (DOC).

While diesel particulate matter build up can prevent regeneration of the Aftertreatment system, air cleaning the DOC reduces Aftertreatment exhaust back pressure and enables the technician to safely run a Parked Regen.

A source of compressed air and a shop vacuum equipped with a 2.5 inch diameter hose (and a dust bag to capture soot removed from the DOC) are also required (not included with kit).

Kit Includes:

  • 13" Aftertreatment Adapter
  • 6" Aftertreatment Adapter
  • Retaining Collar
  • Retaining Straps (3)
  • Customized Blow Gun Assembly

Note: Performing an Aftertreatment diagnostic routing to identify and correct the cause before this face plugging cleaning procedure is recommended. Typical DOC plugging causes are vehicle short duty cycles, excessive idle time, stationary PTO operation, or a hardward issue with the engine.
