The Multiquip 8981562981 DEF Tank Cover Assembly is a genuine OEM component designed for the DCA125SSIU4F ultra-silent diesel generator. As a direct-sourced OEM part, it meets the exact specifications set during original manufacture, ensuring a proper fit and correct function within the DEF system. This assembly is the confirmed replacement for DCA125SSIU4F units requiring DEF tank cover service or replacement.
Key Features
- OEM-Grade DEF Compatibility — Manufactured to resist the corrosive properties of diesel exhaust fluid, maintaining seal integrity and structural integrity around the DEF tank.
- Direct-Fit Installation — Engineered to align with the existing mounting points and fastener pattern on the DCA125SSIU4F, allowing straightforward removal and reinstallation without modification.
- Confirmed Fitment — Verified for the DCA125SSIU4F ultra-silent diesel generator series.
- Emissions System Protection — Shields the DEF tank from contamination, physical damage, and exposure that can compromise the selective catalytic reduction (SCR) system and trigger fault codes.
- Regulatory Compliance Support — A correctly sealed DEF system is essential for Tier 4 Final emissions compliance; a damaged or missing cover risks SCR system contamination and regulatory non-conformance.
The DEF Tank Cover Assembly protects the diesel exhaust fluid reservoir on Tier 4 Final compliant generators, keeping the tank sealed against moisture, debris, and physical damage. DEF is a precision fluid used in the selective catalytic reduction system to reduce nitrogen oxide emissions, and contamination from a compromised cover can lead to SCR system faults, reduced generator output, or automatic engine derate. Replacing a cracked, broken, or missing cover promptly keeps the DEF system functioning correctly and the generator operating within emissions standards.
