The Multiquip 8982984473 DEF Tank Assembly is a genuine OEM component designed for the DCA70SSIU4F ultra-silent diesel generator. As a direct OEM replacement sourced through Multiquip's authorized parts network, it meets the exact specifications required for proper DEF system operation on the DCA70SSIU4F. DHS Equipment supplies this part to keep your generator running in full emissions compliance without the guesswork of fitment verification.
Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional tolerances as the original tank, ensuring correct fluid capacity and secure mounting for the DEF system.
- Direct Assembly Replacement — Supplied as a complete DEF tank assembly, allowing straightforward swap-out with existing mounting hardware and DEF lines on the DCA70SSIU4F.
- Confirmed Fitment for DCA70SSIU4F — Engineered specifically for the DCA70SSIU4F ultra-silent generator series; no cross-referencing or adaptation required.
- Emissions System Integrity — A properly functioning DEF tank is critical for Tier 4 Final emissions compliance; a cracked, leaking, or failed tank can trigger fault codes and force the generator into derate or shutdown mode.
- Regulatory Compliance — Restores the DEF delivery system to its correct operating condition, keeping the DCA70SSIU4F in compliance with EPA Tier 4 Final emissions standards on regulated worksites.
The DEF (Diesel Exhaust Fluid) tank stores the urea solution used by the Selective Catalytic Reduction (SCR) system to reduce harmful nitrogen oxide emissions in Tier 4 Final diesel engines. On the DCA70SSIU4F, the tank feeds DEF to the SCR dosing system at a controlled rate to meet emissions targets during operation. When the tank is damaged, leaking, or contaminated, the SCR system cannot function correctly, which can trigger engine derate warnings, force a shutdown, and cause the unit to fail emissions compliance checks.
