The Multiquip 8982984470 DEF Tank is a genuine OEM component designed for DCA125SSIU4F and DCA70SSIU4F super-silent diesel generator models. As a direct OEM replacement, it is manufactured to the same specifications as the original part, ensuring a correct, hassle-free installation. This tank is confirmed to fit both the standard and 60Hz variants of the DCA70SSIU4F, making it the right choice for operators running either configuration. Sourced directly from Multiquip, this part carries the assurance of authentic OEM quality backed by DHS Equipment.
Key Features
- Authentic OEM Construction — Manufactured to the same material grade and dimensional tolerances as the original factory tank, ensuring proper sealing and structural integrity in DEF fluid service.
- Direct-Fit Installation — Engineered to mount directly into the existing bracket and plumbing connections on compatible generator models with no cutting, adapting, or re-routing of lines.
- Confirmed Fitment — Compatible with DCA125SSIU4F and DCA70SSIU4F (including the 60Hz variant) super-silent diesel generators.
- Protects Tier 4 Emissions Compliance — A correctly functioning DEF tank is essential for maintaining the SCR aftertreatment system operation required on Tier 4 final engines; a cracked or leaking tank can trigger fault codes and de-rate engine output.
- Fluid Integrity Maintained — Constructed from materials compatible with diesel exhaust fluid to resist corrosion and prevent contamination that can damage downstream dosing components.
The DEF (Diesel Exhaust Fluid) tank stores the urea-water solution used by the Selective Catalytic Reduction (SCR) system to reduce nitrogen oxide emissions on Tier 4 diesel engines. The tank feeds DEF to a dosing injector, which introduces it into the exhaust stream where it reacts with exhaust gases to convert harmful NOx into harmless nitrogen and water vapor. When the tank cracks, leaks, or becomes contaminated, the SCR system cannot function correctly, which can result in engine de-rating, fault codes, and potential regulatory non-compliance — making prompt replacement critical to keeping the generator operational and compliant.
