The Multiquip 8983247100 DOC and SCR (DCA400SSI4F3/F3PB) is a genuine OEM emissions control assembly designed for DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, DCA400SSI4F3PD, and DCA400SSI4F3B series Super-Silent and diesel powered generators. As a direct OEM component, this assembly meets the exact emissions and performance specifications Multiquip engineers to these Tier 4 Final ultra-silent generator platforms. Sourced directly from Multiquip, part number 8983247100 ensures compatibility and regulatory compliance without substitution or guesswork. DHS Equipment stocks genuine Multiquip OEM parts to keep your generator operating within specification and in full legal compliance.
Key Features
- Genuine OEM Emissions Assembly — Manufactured to the exact catalytic conversion and reduction specifications required by Multiquip for Tier 4 Final compliant generator operation.
- Direct-Fit Replacement — Engineered to connect and mount to the exhaust aftertreatment system on DCA400SSI4F series generators exactly as the original unit, with no adaptation required.
- Broad DCA400SSI4F Series Coverage — Confirmed fitment across DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, DCA400SSI4F3PD, and DCA400SSI4F3B platforms including Sunbelt-spec units.
- Emissions Compliance Integrity — A failed or degraded DOC/SCR assembly will cause the generator to fall out of Tier 4 Final emissions compliance; this OEM assembly restores the system to its certified operating condition.
- Regulatory and Operational Critical — Proper function of the DOC and SCR system is required for legal operation of Tier 4 Final equipment on regulated worksites — this is not an optional service item.
The Diesel Oxidation Catalyst (DOC) and Selective Catalytic Reduction (SCR) system is the core exhaust aftertreatment assembly responsible for reducing harmful emissions from diesel-powered equipment to meet EPA Tier 4 Final standards. The DOC oxidizes carbon monoxide and unburned hydrocarbons in the exhaust stream, while the SCR uses a diesel exhaust fluid (DEF) reaction to convert nitrogen oxides into harmless nitrogen and water vapor. When this assembly degrades or fails, the generator will produce out-of-compliance exhaust emissions and may trigger fault codes, derate engine output, or shut down entirely — making prompt replacement with a correct OEM part essential.
