Due to the number of exhaust aftertreatment applications, this procedure is generic. Not all illustrations within the
procedure will represent all applications.
The exhaust aftertreatment system is composed for four sections. These sections are:
โข Inlet
โข Aftertreatment Diesel Oxidation Catalyst
โข Aftertreatment Diesel Particulate Filter
โข Outlet
NOTE: In some applications, the catalyst can be integrated into the inlet of the exhaust aftertreatment
system.
NOTE: On some vertically oriented aftertreatment systems, the differential pressure sensor mounting
bracket may be welded to the outlet section of the aftertreatment system. The outlet section of this type of aftertreatment system must be replaced if the differential pressure sensor mounting bracket is damaged.
