NOTE: The aftertreatment diesel particulate filter relies on gas flow through the walls to collect soot. To accomplish
gas flow through the walls of the aftertreatment diesel particulate filter, every other cell on the face of the
aftertreatment diesel particulate filter is plugged with a ceramic material. Therefore, it is not possible to see light
straight through the holes in the aftertreatment diesel particulate filter.
NOTE: lf the aftertreatment diesel particulate filter is being replaced due to progressive damage from engine oil or
fuel, clean the tailpipe from the turbocharger outlet to the aftertreatment diesel oxidation catalyst. Refer to
Procedure 011-048 in Section 11.
Remove any residual gasket material from the flanges on the aftertreatment diesel particulate filter with a scraping
tool.
NOTE: Avoid dropping fragments of gasket material into the aftertreatment diesel particulate filter.
It is not possible to inspect the outlet of the aftertreatment diesel oxidation catalyst or inlet of the aftertreatment
diesel particulate filter on aftertreatment systems with a joined aftertreatment diesel oxidation catalyst aftertreatment diesel particulate filter.
If the filter is believed to be damaged and/or plugged, the entire assembly must be replaced.
If the aftertreatment diesel particulate filter has shifted, moved, or is loose inside the canister, replace the
aftertreatment diesel particulate filter.
If the aftertreatment diesel particulate filter canister is cracked or otherwise damaged, replace the aftertreatment
diesel particulate filter.
Return the aftertreatment diesel particulate filter section to a Cumminsยฎ Authorized Repair Location for cleaning,
replacement, or exchange.
Inspect the V-band clamps and mounting straps for signs of over-extension. The band must not be bent or
damaged.
Inspect the V-band clamp and mounting strap threads for damage.
Replace the V-band clamp or strap if damage is found.
