Key Features
- Genuine OEM Construction — Manufactured to the same specifications as the original DEF tank body, preserving the structural integrity and sealing performance required for diesel exhaust fluid containment.
- Direct-Fit Replacement — Engineered to mount in the exact position of the original assembly on the DCA400SSI4F3PB, using the same mounting points and connection interfaces.
- Confirmed Fitment — Verified for the DCA400SSI4F3PB ultra-silent Tier 4 generator series; check your model code before ordering.
- Emissions System Integrity — A properly functioning DEF tank body is essential to maintaining the Selective Catalytic Reduction (SCR) system, which keeps the generator compliant with EPA Tier 4 Final emissions regulations.
- Fluid Containment Reliability — Replaces cracked, damaged, or leaking DEF tank bodies that can cause SCR system faults, generator shutdowns, or failed emissions checks.
The DEF tank body assembly serves as the primary storage vessel for diesel exhaust fluid (DEF) within the generator's Selective Catalytic Reduction emissions system. DEF is injected into the exhaust stream to break down harmful nitrogen oxide (NOx) emissions, a requirement for Tier 4 Final compliant equipment. When the tank body cracks, leaks, or becomes damaged, the SCR system can fault out, triggering warning codes and forcing the generator offline until the issue is resolved.
