Wacker Neuson 5100034926 Catalyst

The Wacker Neuson Catalyst is a genuine OEM component designed for the RC110 and RC110P series ride-on compactors, including US Rops and US CAB configurations. As a direct OEM replacement, this part is manufactured to the same standards as the original, ensuring it integrates correctly with your machine's exhaust or emissions system without guesswork. Fitment covers the RC110, RC110P, RC110 US Rops, RC110P US Rops, RC110 US CAB, and RC110P US CAB models, making it the right call for operators running any variant in this compactor family. Source your with confidence — this is the same part your machine left the factory with.

Key Features

• OEM Emissions Compliance: — Manufactured to meet the original exhaust aftertreatment specification for the RC110 series, ensuring the machine continues to operate within its designed emissions parameters.
• Direct Drop-In Replacement: — Engineered to match the original mounting configuration and connection points, slotting in exactly where the factory catalyst was installed.
• Broad RC110 Series Coverage: — Fits RC110 and RC110P variants across standard, US Rops, and US CAB configurations — one part number covers the full lineup.
• Restored Exhaust System Efficiency: — A worn or degraded catalyst can cause increased exhaust emissions and potential engine performance issues; replacing it with a genuine OEM unit restores proper exhaust flow and aftertreatment function.
• Emissions System Integrity: — Correct catalyst specification is critical to maintaining regulatory compliance on worksites with emissions requirements — a genuine OEM part ensures the system performs as originally certified.

The catalyst is a core component of the machine's exhaust aftertreatment system. Its job is to chemically convert harmful exhaust gases — such as carbon monoxide and unburned hydrocarbons — into less harmful emissions before they exit the exhaust. On compact equipment like the RC110 series, a functioning catalyst helps the machine meet emissions standards and keeps exhaust output within acceptable limits for enclosed or regulated work environments. When a catalyst degrades or fails, exhaust quality drops, the machine may trigger fault codes, and continued operation can put the equipment out of compliance with emissions regulations.
