Multiquip 8983507160 Filter Kit Pump Assembly DEF DCM Supply

The Multiquip 8983507160 is a genuine OEM Filter Kit Pump Assembly DEF DCM Supply designed for DCA400SSI4F series Super-Silent diesel generators, including the DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, DCA400SSI4F3PD, and DCA400SSI4F3B variants. As a factory-sourced component, this kit delivers the exact fit and specification required to keep the DEF (Diesel Exhaust Fluid) dosing control module supply pump operating correctly in Tier 4 Final emissions-compliant units. Sourcing a genuine OEM kit like part 8983507160 ensures the DEF system continues to function within the emissions parameters these generators are engineered to meet. DHS Equipment supplies this part direct, so you can order with confidence in both authenticity and compatibility.

Key Features

• Genuine OEM DEF System Integrity — Factory-sourced filtration components matched to the DEF pump assembly's flow rate and chemical resistance requirements, ensuring the dosing system operates as designed.
• Direct-Fit for DCA400SSI4F Series — Engineered specifically for DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, DCA400SSI4F3PD, and DCA400SSI4F3B generators — connects and seals to OEM interfaces without adaptation.
• Tier 4 Final Emissions Compliance — Replacing this filter kit on schedule keeps the DEF supply pump delivering the precise fluid volume required to sustain Tier 4 Final NOx reduction performance on these Super-Silent units.
• Protects the DEF Dosing Pump — Clean filtration prevents particulate contamination from reaching the precision metering components of the DCM supply pump assembly, extending pump service life.
• Correct Part for Multi-Configuration Models — Covers multiple DCA400SSI4F build variants, including Sunbelt-spec units, so technicians can order a single verified part number across the generator family.

The DEF (Diesel Exhaust Fluid) pump assembly on Tier 4 Final generators is responsible for drawing fluid from the tank and delivering it to the selective catalytic reduction (SCR) system at a controlled rate to reduce NOx emissions. The DCM (Dosing Control Module) supply circuit depends on clean, unobstructed fluid flow — a clogged or degraded filter within this assembly restricts delivery, triggering fault codes and potentially forcing the generator into a derated or shutdown condition. Replacing the filter kit at the manufacturer's recommended intervals keeps the DEF system primed and accurate, protecting both emissions compliance and uninterrupted power output.
