Component
• Use the following procedure to install the aftertreatment inlet or outlet sections. Refer to Procedure 011-048 in Section 11.
• Use the following procedure to install the aftertreatment diesel oxidation catalyst. Refer to Procedure 011-049 in Section 11.
• Use the following procedure to install the aftertreatment diesel particulate filter or joined aftertreatment diesel oxidation catalyst-aftertreatment diesel particulate filter. Refer to Procedure 011-041 in Section 11.
NOTE: Make sure the aftertreatment system is oriented so the aftertreatment diesel particulate filter differential
pressure sensor is installed in the same orientation noted during disassembly.
NOTE: The aftertreatment system must be installed so the aftertreatment diesel particulate filter differential
pressure sensor tubes slope downward to drain condensation away from the differential pressure sensor.
NOTE: Make sure the differential pressure sensor tubes are not making contact with each other or any other
vehicle components prior to tightening the Torca”‘ clamps or v-band clamps.
System
• Install the straps or bolts that secure the aftertreatment system to the vehicle chassis. Refer to the OEM service manual.
• Install the inlet and outlet of the aftertreatment on to the exhaust pipe. Refer to Procedure 011-048 in Section 11.
NOTE: If a TorcaTM clamp is replaced during service, be sure to replace it with another Torca”‘ clamp. Do not use
a u-bolt as a replacement clamp. U-bolt clamps can crush the tailpipe and make it difficult to remove the aftertreatment system for future service.
• Apply a coat of anti-seize compound on the threads of the v-band clamps and Torca”‘ clamps.
• Tighten the Torca”‘ clamps used to secure the inlet and outlet of the aftertreatment to the exhaust pipe. Refer
to Procedure 011-048 in Section 11.
• Connect the exhaust temperature sensor to the wiring harness connectors. Use the following procedure in
the Troubleshooting and Repair Manual CM2150 Electronic Control System, ISB, ISC, ISL ISLe ISDe and QSB3.3 Engines, Bulletin 4021570. Refer to Procedure 019-449 in Section 19.
• Connect the aftertreatment diesel particulate filter differential pressure sensor wiring harness connector.
Use the following procedure in the Troubleshooting and Repair Manual CM2150 Electronic Control System, ISB, ISC, ISL ISLe ISDe and QSB3.3 Engines, Bulletin 4021570. Refer to Procedure 019-443 in section 19.
