While diesel particulate matter buildup can prevent regeneration of the aftertreatment system, reverse-flow air cleaning the DOC reduces AFT exhaust back-pressure and enables the technician to safely run a parked regen.
The Aftertreatment Service Kit includes a 13-inch aftertreatment adapter, retaining collar, retaining straps and blowgun assembly. Not included in the kit are a source of compressed air, a shop vacuum equipped with a 2.5-foot-diameter hose and a dust bag to capture soot removed from the DOC.
