Overview – DEVICE, AFTERTREATMENT 3964072 Series
The Cummins DEVICE, AFTERTREATMENT 3964072 fits Cummins aftertreatment system positions as the aftertreatment device; because multiple part numbers interchange, we list the related series so you can match what is on your machine.
Parts Characteristics
An aftertreatment device that carries the exhaust through the emissions-control stage, holding the conversion surface the system depends on to meet spec. It carries hot, corrosive gas under load, so a true, undamaged device keeps the aftertreatment working and the engine out of derate.
Applicable Models & Applications
Used on Cummins aftertreatment routes specifying this device (series configuration). Match the device to the aftertreatment family and the emission level it supports – aftertreatment devices differ by platform and calibration.
Maintenance & Replacement
Inspect the device for a cracked can and a leaking joint at every aftertreatment service. A device that has started to leak passes raw exhaust, and the leak is what trips the fault code.
Replace the device as a matched set where the job calls for it. A new device onto a reused clamp still leaks, and the leak is what defeats the conversion.
Confirm the flow direction and the mounting are correct on fit. A device reversed or loose converts nothing and the system runs cold.
Keep the correct aftertreatment devices for your engine family available. They are load-critical, and an engine stopped on aftertreatment is an engine waiting on a large part.
