The Wacker Neuson 5100046110 Muffler Complete SCR is a genuine OEM exhaust aftertreatment assembly for Wacker Neuson Tier 4 Final diesel-powered equipment. "SCR" denotes selective catalytic reduction — this is not a simple silencer but a complete muffler and catalyst unit that reduces nitrogen oxide (NOx) emissions using diesel exhaust fluid (DEF). It is built to the same specifications as the factory-installed part, restoring correct exhaust flow, back-pressure, catalyst function, and sound attenuation on machines that require an SCR system to remain emissions-compliant.
Key Features
- Genuine OEM SCR Assembly: Complete muffler with integrated selective catalytic reduction catalyst, manufactured to Wacker Neuson's original specifications for flow, heat rating, and catalyst loading.
- Emissions Compliance Restored: Returns the machine's exhaust aftertreatment to factory NOx reduction performance, clearing SCR-related fault codes and derate conditions caused by a damaged or depleted catalyst.
- Direct Replacement Fit: Matches original inlet and outlet connections, DEF injector and sensor ports, and mounting points, so the assembly installs in the factory location without modification.
- Protects Engine Performance: A correctly functioning SCR muffler maintains the back-pressure the engine's fuel mapping is calibrated around, supporting full rated power and normal fuel consumption.
- Complete Unit: Supplied as a full assembly rather than a bare catalyst or shell, reducing labor time and avoiding mismatched components.
On Tier 4 Final diesel equipment, the SCR muffler is the final stage of the exhaust aftertreatment system. Exhaust gases pass through the catalyst, where injected DEF converts NOx into nitrogen and water vapor before exiting the machine. When the catalyst is contaminated, cracked, or thermally degraded, the engine control unit detects out-of-range NOx or temperature readings and will typically log a fault and progressively derate the engine until the system is repaired. Symptoms of a failing SCR muffler include persistent aftertreatment warning lights, reduced power, increased DEF consumption, and audible exhaust leaks. Because internal catalyst damage usually cannot be repaired, replacement with the complete OEM assembly is the standard service procedure.
