Cummins ISX11.9 CM2250 – Service Manual 011-050   Aftertreatment System

NOTE: Use the following procedures to install the aftertreatment system by system.

Make sure the aftertreatment system is oriented so that the aftertreatment diesel particulate filter differential pressure sensor is installed in the same orientation noted during disassembly.

The aftertreatment system must be installed so that the aftertreatment diesel particulate filter differential pressure sensor tubes slope downward to drain condensation away from the differential pressure sensor.

Make sure the differential pressure sensor tubes are not making contact with each other or any other vehicle components prior to tightening the clamps.

Install the straps or bolts that secure the aftertreatment system to the vehicle chassis. Refer to the OEM service manual.
