Multiquip 8981694080 Cover Kit Pump Assembly DEF DCM Supply

The Multiquip 8981694080 is a genuine OEM Cover Kit Pump Assembly DEF DCM Supply designed for the DCA400SSI4F series super-silent generators, including the DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3B, DCA400SSI4F3PB, and DCA400SSI4F3PD variants. As a direct Multiquip OEM component, part 8981694080 is produced to the same specifications as the original assembly, ensuring correct fitment across the DCA400SSI4F generator family. This cover kit is a critical service component for maintaining the integrity of the DEF diesel exhaust fluid supply system on Tier 4 Final compliant units. Source this part through DHS Equipment for confidence in fitment accuracy and genuine OEM quality.

Key Features

• Genuine OEM Construction — Manufactured to original Multiquip specifications, ensuring the DEF pump assembly cover seats, seals, and mounts exactly as the factory-installed component.
• Tier 4 Final DEF System Compatibility — Engineered specifically for the diesel exhaust fluid supply system on DCA400SSI4F Tier 4 Final super-silent generators, where DEF system integrity is required for emissions compliance.
• Broad DCA400SSI4F Series Fitment — Confirmed compatible with DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3B, DCA400SSI4F3PB, and DCA400SSI4F3PD units, covering the full DCA400SSI Tier 4 generator lineup.
• Protects DEF Pump Components — The cover assembly shields internal DEF pump components from contamination, physical damage, and environmental exposure, preserving consistent DEF dosing accuracy.
• Emissions System Compliance — Correct fitment of this cover kit helps maintain the sealed DEF supply circuit required for Tier 4 Final emissions system operation — a genuine compliance-relevant component on regulated equipment.

The DEF (diesel exhaust fluid) supply pump assembly is part of the selective catalytic reduction (SCR) emissions system found on Tier 4 Final diesel generators such as the DCA400SSI4F series. This system injects a precise quantity of DEF into the exhaust stream to reduce nitrogen oxide emissions to compliant levels. The cover kit protects the DEF pump assembly from dirt, moisture, and mechanical damage — a compromised or missing cover can expose the pump to contamination, leading to dosing faults, emissions system warnings, or pump failure that can take the generator offline.
