The Wacker Neuson is a genuine OEM Brush Assembly designed for the GP3800A, GP5600A, GP6600A, GPS5600A, GPS6600A, GV3800A, GV5600A, GV6600A, and GP4000 series portable generators. As a direct factory replacement, this part is manufactured to the same specifications as the original, ensuring correct contact geometry and brush material grade for consistent electrical transfer in the alternator. This Brush Assembly covers an extensive range of Wacker Neuson GP, GPS, and GV generator configurations, including wheel kit, electric start, CARB, EPA, CSA, and CAN GFI variants.
Key Features
- OEM Carbon Brush Material — Factory-spec brush compound ensures correct conductivity and wear rate against the slip ring, maintaining stable voltage output over the service interval.
- Direct Alternator Drop-In — Engineered to match the original brush holder dimensions and spring tension, allowing the assembly to seat and secure without rework or shimming.
- Broad GP, GPS, and GV Series Coverage — Fits GP3800A, GP5600A, GP6600A, GPS5600A, GPS6600A, GV3800A, GV5600A, GV6600A, and GP4000 portable generators across EPA, CARB, CSA, and CAN GFI configurations.
- Restore Consistent Power Output — Worn brushes cause voltage fluctuation, output drop, or complete loss of AC power; replacing the Brush Assembly with part 5000162490 restores full, stable generator output.
- Electrical Safety Compliance — Correct brush contact pressure and material grade are critical to safe alternator operation; using the genuine OEM assembly maintains the electrical integrity of the generator's output circuit.
The Brush Assembly is a critical wear component inside the generator's alternator. Carbon brushes ride against a rotating slip ring to transfer the excitation current that allows the alternator to produce AC power. As the brushes wear down over time, contact becomes intermittent or is lost entirely, causing the generator to produce unstable voltage, surge, or stop generating power altogether. Replacing the Brush Assembly with a correctly rated OEM part restores full electrical contact and brings the generator back to its rated output.
