Wacker Neuson 5100034931 Catalyst

The Wacker Neuson Catalyst is a genuine OEM component designed for the RC110 and RC110P series remote-controlled compactors, including ROPS and CAB-configured models. As a direct factory replacement, this part meets the exact specifications set by Wacker Neuson for emissions and exhaust aftertreatment on these machines. Sourcing the correct OEM catalyst ensures the exhaust system continues to operate as intended without requiring modifications or adaptations to the surrounding components. If your RC110 or RC110P is showing exhaust-related fault codes or reduced performance, replacing the catalyst with part number is the correct factory-specified repair path.

Key Features

• OEM Emissions Compliance: — Manufactured to Wacker Neuson's exact exhaust aftertreatment specification, ensuring the correct substrate composition and flow characteristics for this engine application.
• Drop-In Fitment: — Engineered to match the original mounting configuration, inlet and outlet dimensions, and connection points on the RC110 and RC110P exhaust system for a straightforward swap.
• Broad RC110 Series Coverage: — Confirmed fitment across RC110, RC110P, RC110 US ROPS, RC110P US ROPS, RC110 US CAB, and RC110P US CAB machine configurations.
• Restored Exhaust Performance: — A functioning catalyst maintains proper exhaust gas conversion; a degraded or failed unit can trigger fault codes, derate engine output, or cause the machine to shut down entirely.
• Emissions System Integrity: — Replacing a worn catalyst with the correct OEM part keeps the exhaust aftertreatment system operating within required emissions parameters, which is directly relevant to regulatory compliance on regulated job sites.

A catalyst is a core component of the exhaust aftertreatment system, responsible for converting harmful exhaust gases into less harmful byproducts before they exit the machine. In remote-controlled compactors like the RC110 series, the catalyst works in tandem with the engine management system to meet emissions standards and maintain smooth operation. When the catalyst degrades, becomes clogged, or fails, the engine control unit will typically detect abnormal exhaust conditions, leading to fault codes, reduced power output, or automatic shutdown — making timely replacement critical to keeping the machine productive.
