The Wacker Neuson 5000087838 Brush Complete is a genuine OEM component designed for the GP-family portable generator lineup, including the GPS9700, GPS8500, GS-series, and G-series generators. Sourced directly through Wacker Neuson's authorized parts program, this Brush Complete matches the original specification installed at the factory. It is compatible across a broad range of 50Hz and 60Hz Wacker Neuson portable generator models — including the G3.3A, G3.7A, G4.6A, G5.6A, G5.7A, GS4.6A, GS5.7A, GPS9700, and GPS8500 families — making it a stocking staple for service technicians and fleet operators alike.
Key Features
- Genuine OEM Carbon Grade — manufactured to the exact carbon compound and dimensional spec used in original Wacker Neuson generator production, ensuring correct brush-to-slip-ring contact and consistent voltage output.
- Drop-In Brush Holder Fit — designed to seat directly into the factory brush holder assembly without machining or shimming, keeping brush spring tension within the designed operating range.
- Broad Generator Family Coverage — a single part number covers GPS9700, GPS8500, and the full G3.3A through G5.7A series, including electric-start and standard variants across both 50Hz and 60Hz configurations.
- Protects Alternator Output Quality — worn brushes cause fluctuating or lost AC voltage output; a fresh Brush Complete restores stable excitation current to the rotor and consistent power delivery to connected loads.
- Electrical Safety Compliance — correct brush material and contact pressure prevent arcing and excessive heat buildup at the slip ring, reducing the risk of insulation damage or uncontrolled voltage spikes.
The brush assembly maintains electrical contact between the stationary wiring and the rotating rotor inside the generator's alternator. It carries excitation current to the rotor windings, which creates the magnetic field needed to generate AC power at the output terminals. As brushes wear down from normal friction, contact becomes inconsistent — leading to voltage fluctuations, reduced output, or a complete loss of power generation. Replacing the Brush Complete at the first sign of output irregularity restores proper excitation and protects the alternator from secondary wear on the slip rings.
