The Multiquip DZ103065 DEF Tank is a genuine OEM component designed for DCA70SSJU4F super-silent diesel generators. As a direct OEM replacement, this tank is sourced to the same specifications as the original unit installed at the factory, ensuring a correct, hassle-free installation. Confirmed fitment includes the DCA70SSJU4F series, covering both the standard and 60Hz diesel-powered generator configurations sold under the Multiquip super-silent lineup.
Key Features
- Genuine OEM Construction — Manufactured to the same material and capacity standards as the original DEF tank, ensuring proper fluid containment and resistance to DEF-related corrosion.
- Direct-Fit Installation — Designed to mount using the original bracket points and fluid line connections on the DCA70SSJU4F, keeping replacement straightforward for service technicians.
- Confirmed Fitment — Compatible with DCA70SSJU4F super-silent generators, including 60Hz diesel-powered variants in the Multiquip DCA series.
- Emissions System Integrity — A properly functioning DEF tank keeps the Selective Catalytic Reduction (SCR) system supplied, allowing the generator to meet Tier 4 Final emissions requirements without fault codes or derate conditions.
- Fuel and Fluid Compatibility — Built to hold diesel exhaust fluid (DEF/AdBlue) without degradation, maintaining tank integrity over extended service intervals.
The DEF tank stores diesel exhaust fluid used by the generator's Selective Catalytic Reduction system to reduce nitrogen oxide emissions in Tier 4 Final-compliant engines. The SCR system injects DEF into the exhaust stream, triggering a chemical reaction that converts harmful NOx emissions into harmless nitrogen and water vapor. When the DEF tank cracks, leaks, or fails, the generator's emissions control system is disrupted — often triggering fault codes, automatic power derating, or a full machine shutdown until the issue is resolved.
