The Wacker Neuson DEF Tank Assembly is a genuine OEM component designed for the G150, G180, and G230 series mobile generators, including Standard, Cold Weather, Custom, and 600V Tier 4 Final configurations. As a direct OEM replacement, this tank assembly is built to the exact specifications of the original unit, ensuring correct fluid capacity, connection alignment, and material compatibility with Wacker Neuson's Tier 4 Final emissions systems. Fitment extends across a wide range of G-series generator configurations, including Transport Canada-certified models, making this a versatile service part for mixed fleets. Keep part number on hand to minimize unplanned service delays on your generator equipment.

Key Features

  • OEM-Matched Tank Capacity and Material — Manufactured to hold the correct DEF volume with chemical-resistant construction that prevents fluid degradation and sensor interference.
  • Drop-In Replacement Fit — Mounts directly to original brackets and connects to existing DEF lines and sensors without reworking the surrounding assembly.
  • Broad G-Series Compatibility — Fits G150, G180, and G230 mobile generators across Standard, Cold Weather, Custom, and 600V variants, including Tier 4 Final and Transport Canada-certified units.
  • Supports Continuous Tier 4 Final Compliance — A properly functioning DEF tank ensures uninterrupted DEF supply to the selective catalytic reduction system, keeping emissions output within EPA Tier 4 Final limits.
  • Emissions System Integrity — A failed or cracked DEF tank can trigger fault codes, force generator derate, or cause a full shutdown — replacing with a genuine OEM unit restores correct system operation and avoids regulatory exposure on the jobsite.

The DEF (Diesel Exhaust Fluid) tank stores the urea-water solution used by the generator's selective catalytic reduction (SCR) system to neutralize nitrogen oxide emissions. Without a functioning DEF tank supplying fluid at the correct rate, the SCR system cannot operate, and Tier 4 Final-compliant generators will derate or shut down to remain within emissions regulations. A cracked, leaking, or contaminated tank compromises the entire emissions control circuit and can result in fault codes that take the machine out of service until the issue is resolved.
