The Honda 31215-ZA1-013 Brush is a genuine OEM replacement designed for a wide range of Honda engines, generators, tillers, riding mowers, and lawn tractors. This is a direct Honda OEM component, manufactured to the same specification as the original, ensuring consistent electrical contact and output across every application it covers. This brush is confirmed for use on G300, G400, and GX360 horizontal shaft engines; GXV270, GXV340, and GXV390 vertical shaft engines; EMS4000, EMS4500, ES4500, ES6500, EV4000, and EX5500 generators; the FR700 tiller; and H1011, H2013, H3011, H3013, H4013, H4514, HT3810, HT3813, and HT4213 riding mowers and lawn tractors. Because Honda supersedes parts at production breaks, confirm your unit's serial number against the fitment table before ordering.
Key Features
- Genuine OEM Electrical Contact — manufactured by Honda to maintain consistent brush-to-commutator or brush-to-slip-ring contact, ensuring stable current transfer rather than the intermittent output a worn brush produces
- Broad Cross-Application Fit — a single part number covering generators, horizontal and vertical shaft engines, a tiller, riding mowers, and lawn tractors; verify part number 31215-ZA1-013 against your model and serial number before installation
- Serial Number Verification Recommended — Honda updates part numbers at production breaks, so always cross-check your machine's serial number against the compatibility table to confirm this is the correct brush for your unit
- Restored Charging and Output Performance — a worn or degraded brush causes voltage drop, erratic output, or complete charging failure; replacing it with this OEM brush restores proper electrical performance to the machine
A brush is a small carbon or carbon-composite block that maintains sliding electrical contact with a rotating commutator or slip ring inside a starter motor, charging circuit, or alternator. As the rotor spins, the brush transfers current between the stationary and rotating parts of the assembly. Over time, brushes wear down through normal friction, eventually losing consistent contact and causing symptoms such as hard starting, weak charging output, or complete electrical failure. Replacing a worn brush with a correct OEM component restores full electrical contact and returns the machine to normal operation.
