Apply a coat of anti-seize compound on the threads of the v-band clamps and Torca® clamps.
The aftertreatment outlet section contains a differential pressure sensor tube boss. Align the differential pressure
sensor tube boss with the differential pressure sensor tube nut prior to tightening the v-band clamp or the Torca®
clamp.
NOTE: If the Torca® clamp is replaced during service, be sure to replace it with another Torca® clamp. Do not use
au-bolt as a replacement clamp. U-bolt clamps can crush the tailpipe and make it difficult to remove the aftertreatment system for future service.
NOTE: Install a new gasket between the exhaust pipe and aftertreatment inlet if a gasket was present during removal.
Tighten the Torca® clamps or v-band clamps used to secure the inlet and outlet of the aftertreatment to the
exhaust pipe.
Install a new gasket between the v-band clamp joints that have been disconnected.
Install the v-band clamp used to connect the outlet to the aftertreatment diesel particulate filter, if necessary.
Install the v-band clamp use to connect the inlet to the aftertreatment diesel oxidation catalyst, if necessary.
Tighten the v-band clamps.
