Overview – SECONDARY THREE WAY CATALYST E5511134
For Cummins aftertreatment positions as the secondary three-way catalyst, the Cummins SECONDARY THREE WAY CATALYST E5511134 provides the correct fit and performance expected from a genuine-spec replacement.
Parts Characteristics
A secondary three-way catalyst that carries the exhaust through the reduction and oxidation stage, converting the pollutants to meet spec. It carries hot, reactive gas under load, so a true, undamaged catalyst keeps the emissions stage working and the engine out of derate.
Applicable Models & Applications
Used on Cummins aftertreatment routes specifying this secondary catalyst. Match the catalyst to the aftertreatment family and the emission level it supports – catalysts differ by platform and calibration.
Maintenance & Replacement
Inspect the catalyst for a crushed can and a leaking joint at every aftertreatment service. A catalyst that has begun to leak passes raw exhaust, and the leak is what trips the fault code.
Replace the catalyst as a matched set where the job calls for it. A new catalyst 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 catalyst reversed or loose converts nothing and the system runs cold.
Keep the correct secondary three-way catalysts for your engine family available. They are load-critical, and an engine stopped on aftertreatment is an engine waiting on a large part.
