The Multiquip 8982848861 Dosing Control Unit is a genuine OEM component designed for the DCA400SSI4F ultra-silent diesel generator. As a direct OEM replacement, this part is sourced to the same specifications as the original unit installed at the factory, ensuring correct integration with the DCA400SSI4F emissions and engine management system. If your generator is displaying dosing faults, reduced output, or Tier 4 compliance issues, replacing this unit with the correct Multiquip 8982848861 is the straightforward path to restoring proper operation.
Key Features
- Genuine OEM Emissions Accuracy — Manufactured to the precise calibration required for Tier 4 Final DEF dosing control, ensuring the DCA400SSI4F meets its rated emissions compliance thresholds.
- Direct-Fit Replacement — Engineered to connect directly to the existing wiring harness and mounting points on the DCA400SSI4F, with no adapter modifications needed to the electrical interface.
- DCA400SSI4F Compatibility — Confirmed fitment for the Multiquip DCA400SSI4F ultra-silent Tier 4 diesel generator series.
- Restores Aftertreatment Performance — A correctly functioning dosing control unit regulates DEF injection into the exhaust aftertreatment system; a failed unit can trigger fault codes, derate engine output, or shut the generator down entirely.
- Emissions System Compliance — Critical for maintaining Tier 4 Final regulatory compliance on worksites where emissions standards are enforced; installing the correct OEM unit keeps the aftertreatment system operating within certified parameters.
The dosing control unit manages the precise injection of diesel exhaust fluid (DEF) into the selective catalytic reduction (SCR) aftertreatment system on Tier 4 Final compliant generators like the DCA400SSI4F. It monitors exhaust conditions and signals the DEF dosing pump to inject the correct quantity of fluid to reduce nitrogen oxide (NOx) emissions to within regulatory limits. When this unit fails or falls out of calibration, the generator's engine management system will typically log fault codes, reduce power output as a protective measure, or prevent the unit from starting altogether — making prompt replacement essential for uninterrupted operation.
