The Multiquip M3424701004 DEF Tank Cover B is a genuine OEM component designed for the DCA150SSJU4F ultra-silent diesel generator. Sourced directly from Multiquip, this cover is manufactured to the same specification as the original part fitted at the factory, ensuring a correct, trouble-free installation. If your DCA150SSJU4F is showing wear, damage, or a missing cover on its DEF tank, M3424701004 is the verified replacement to restore it.
Key Features
- Genuine OEM Construction — Manufactured to original design tolerances, ensuring the cover seats, seals, and mounts exactly as the factory-fitted unit on the DCA150SSJU4F.
- Direct-Fit Replacement — Matches the original mounting points and profile of the DEF tank assembly, so installation requires no modification to surrounding components.
- Confirmed Fitment — Verified for the Multiquip DCA150SSJU4F ultra-silent diesel generator series.
- DEF System Protection — Shields the diesel exhaust fluid tank from debris, moisture, and physical damage that could compromise the emissions control system or contaminate the DEF supply.
- Emissions Compliance Support — Maintaining an intact DEF tank cover is essential to the correct operation of the Tier 4 selective catalytic reduction (SCR) system; a damaged or absent cover can expose the DEF system to conditions that trigger fault codes or regulatory non-compliance.
The DEF Tank Cover B protects the diesel exhaust fluid reservoir on Tier 4-compliant generators from environmental exposure, physical impact, and contamination. DEF is highly sensitive to impurities, and without a properly fitted cover, the fluid can degrade or become contaminated, causing the SCR emissions system to malfunction and potentially triggering engine derate conditions. Keeping this cover intact and correctly seated is a straightforward but critical part of maintaining both emissions compliance and uninterrupted generator operation.
