The Honda 31106-ZB4-003 Brush Assembly is a genuine OEM component designed for Honda conventional generators, including the EB3500, EB5000, EB6500, EG3500, EG5000, EM3500, EM5000, EM6000, EN3500, EN5000, ES6500, EX3300, EX4500, EX5500, EZ3500, and EZ5000. As a direct Honda OEM replacement, this Brush Assembly is manufactured to the same specification as the original, ensuring correct contact geometry and electrical conductivity within the alternator. Verify your generator's model and serial number against the fitment table before ordering, as Honda supersedes parts at specific production breaks.
Key Features
- Genuine OEM Alternator Contact — Honda-sourced carbon brush material matched to the contact pressure and conductivity requirements of these generators' alternators, not an approximated aftermarket substitute.
- Direct OEM Replacement — Engineered to the original dimensions and profile, this Brush Assembly drops into place without modification, restoring proper rotor-to-brush contact in the alternator.
- Broad Generator Compatibility — Fits a wide range of Honda conventional generators, including the EB3500, EB5000, EB6500, EG5000, EM5000, EM6000, EN5000, ES6500, EX4500, EX5500, EZ5000, and more.
- Serial Number Verification Recommended — Honda updates part supersessions at defined production points; always confirm your generator's serial number against the fitment table to ensure this is the correct brush for your unit.
- Stable Voltage Output — Worn or degraded brushes cause erratic or failed voltage regulation in a conventional alternator. Replacing this assembly with the correct OEM part restores consistent electrical output to the generator.
The Brush Assembly is a critical component in the alternator of a conventional generator. Carbon brushes maintain continuous electrical contact with the spinning rotor's slip rings, allowing the alternator's automatic voltage regulator to control the rotor's magnetic field and, in turn, stabilize the generator's output voltage. As the brushes wear down through normal use, contact becomes intermittent, leading to fluctuating voltage, loss of power output, or a generator that fails to excite and produce electricity at all. Replacing a worn Brush Assembly with a genuine Honda part restores full alternator function and steady power delivery.
