The Multiquip 8982861764 is a genuine OEM Urea Water Tank designed for the DCA400SSI4F series super-silent generators, including the DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, and DCA400SSI4F3PD. As a factory-original component, it meets the exact specifications required to keep the DEF (Diesel Exhaust Fluid) system operating correctly on these Tier 4 Isuzu-powered units. Sourced directly through Multiquip's OEM supply chain, this part is a direct replacement for the original tank installed at the factory. Confirm your model code against the fitment list before ordering to ensure a correct match.
Key Features
- OEM-Grade DEF Compatibility — Manufactured to resist DEF (urea solution) corrosion, ensuring the tank does not degrade or contaminate the fluid over time.
- Direct-Fit Replacement — Engineered to the original mounting dimensions and port locations for the DCA400SSI4F series, allowing installation without modification to brackets or fittings.
- Broad DCA400SSI4F Series Coverage — Fits DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, and DCA400SSI4F3PD super-silent and Tier 4 diesel generator variants.
- Emissions System Integrity — A properly functioning urea tank is essential to the SCR (Selective Catalytic Reduction) system; a failed or leaking tank can trigger fault codes and take the generator offline.
- Tier 4 Compliance Support — Replacing a damaged tank with a genuine OEM unit helps maintain the emissions compliance required for Tier 4 final engine operation on regulated job sites.
The urea water tank stores the DEF solution — a mixture of purified water and automotive-grade urea — used by the generator's Selective Catalytic Reduction system to reduce nitrogen oxide (NOx) emissions in line with Tier 4 final regulations. The SCR system injects this fluid into the exhaust stream, where it converts harmful NOx gases into harmless nitrogen and water vapor. If the tank cracks, leaks, or becomes contaminated, the SCR system cannot dose correctly, which can result in fault codes, automatic derating, or a generator shutdown — making prompt replacement with the correct OEM part critical to uninterrupted operation.
