Draw an orientation reference line across each of the V- band clamps, aftertreatment canister sections, and
connection points to the tailpipe. This will aid in linking up sections and V-band clamps to their original orientation
during installation.
Mark the direction of exhaust flow on both the aftertreatment diesel oxidation catalyst section and the aftertreatment diesel particulate filter section to aid in assembly.
NOTE: If necessary, remove additional mounting hardware to remove the aftertreatment diesel oxidation
catalyst from the vehicle.
Remove the V-band clamps from the inlet and outlet of the aftertreatment diesel oxidation catalyst.
Separate the component sections by approximately 25 mm [1 in] to allow removal over the gasket retainer rings.
Remove and discard the gaskets.
