The Honda 31106-ZA7-003 Brush Assembly is a genuine OEM component designed for the EX800 generator. Sourced directly from Honda, this assembly matches the original specification exactly, ensuring a direct, hassle-free installation. If your EX800 is showing reduced or erratic electrical output, a worn brush assembly is a common cause — and this is the correct OEM replacement to restore it.
Key Features
- Genuine OEM Electrical Contact — Honda-sourced carbon brushes maintain consistent contact pressure against the slip rings, which is essential for steady voltage output from the EX800 alternator.
- Direct OEM Replacement — This assembly installs in place of the original without alteration, using Honda part number 31106-ZA7-003 for confirmed fitment on the EX800 generator.
- Restores Proper Output — Worn or shortened brushes cause voltage drop and unstable power delivery; replacing this assembly brings the generator back to its rated electrical performance.
- Verify Serial Number Before Ordering — Honda updates parts at production serial breaks, so confirm your EX800 serial number against the fitment table to ensure this is the correct assembly for your unit.
The brush assembly carries electrical current from the stationary wiring to the rotating components of the generator's alternator via spring-loaded carbon brushes that ride against slip rings on the rotor. As the brushes wear down through normal use, contact becomes inconsistent, leading to fluctuating voltage, reduced output, or a complete loss of power generation. Replacing a worn brush assembly is one of the most straightforward generator service tasks and is essential to keeping the EX800 producing clean, stable electrical output.
