The Multiquip M3424700003 DEF Tank Cover is a genuine OEM component designed for DCA150SSJU4F and DCA220SSJU4F super-silent generator models. Sourced directly from Multiquip, this cover is built to the same specifications as the original part installed at the factory, ensuring a proper fit and long-term durability in demanding jobsite environments. Confirmed fitment includes both the DCA150SSJU4F and DCA220SSJU4F series, including the 60Hz variant of the DCA220SSJU4F.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications, delivering the same protective coverage as the part it replaces.
- Secure DEF System Protection — Shields the diesel exhaust fluid tank from contamination, debris, and physical damage that could compromise emissions system integrity.
- Direct-Fit Replacement — Engineered to align with the original mounting points on compatible generator models, allowing straightforward installation without modification.
- Confirmed Fitment — Compatible with DCA150SSJU4F and DCA220SSJU4F super-silent generators, including the 60Hz DCA220SSJU4F configuration.
- Emissions System Compliance — A properly seated DEF tank cover helps maintain the sealed DEF system required for Tier 4 emissions compliance; a damaged or missing cover can expose the DEF supply to contamination and lead to system faults.
The DEF tank cover protects the diesel exhaust fluid reservoir on Tier 4 compliant generators, keeping the DEF supply clean and sealed from dust, moisture, and debris. DEF is highly sensitive to contamination — even small amounts of foreign material can degrade fluid quality and trigger emissions system faults that take the generator offline. A cracked, missing, or improperly fitted cover puts the entire selective catalytic reduction system at risk, making timely replacement of this component essential to uninterrupted operation.
