The Multiquip M3424700104 DEF Tank Cover is a genuine OEM component designed for DCA-series ultra-silent diesel generators, including the DCA150SSJU4F, DCA220SSJU4F, and DCA300SSJU4F. As a direct OEM replacement, it meets the same fit and material standards as the original part that shipped with the machine. Sourced directly through authorized Multiquip supply channels, M3424700104 is verified for compatibility across both 50Hz and 60Hz configurations of these generator models. If you are servicing or restoring a DCA-series unit, this is the correct cover for the DEF tank assembly.
Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional standards as the original, ensuring the cover seats correctly and provides a secure seal over the DEF tank.
- Direct-Fit Replacement — Engineered to drop into the existing DEF tank housing on DCA-series generators without alteration to surrounding components.
- Broad DCA-Series Compatibility — Confirmed fitment for DCA150SSJU4F, DCA220SSJU4F, and DCA300SSJU4F models, covering both 50Hz and 60Hz variants.
- DEF System Integrity — A properly fitted cover keeps the diesel exhaust fluid reservoir protected from contamination and debris, which is critical to consistent Tier 4 emissions system performance.
- Emissions Compliance Support — Protecting the DEF tank from exposure helps maintain the SCR system's ability to meet Tier 4 Final emissions standards — a regulatory requirement on these generator models.
The DEF tank cover shields the diesel exhaust fluid reservoir on Tier 4-compliant generators from dust, moisture, and physical damage. DEF is a precision fluid used by the selective catalytic reduction system to reduce harmful NOx emissions; any contamination introduced through a missing or damaged cover can compromise fluid quality and trigger fault codes that take the generator offline. Keeping this cover intact and properly secured is a straightforward part of maintaining both emissions compliance and uninterrupted generator operation.
