The Honda 31200-ZE8-801 Starter Motor Assembly is a genuine OEM component designed for GXV270, GXV340, and GXV390 vertical shaft engines. As a direct Honda OEM replacement, this starter motor assembly is manufactured to the same specification as the original unit, ensuring correct engagement, proper cranking torque, and trouble-free installation. Confirm your engine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and more than one assembly may be listed for these models.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this assembly delivers the correct brush configuration, armature winding, and pinion engagement your engine's starting circuit calls for — not an approximation of it.
- Consistent Cranking Performance — a functioning starter motor assembly spins the engine to firing speed every time the key is turned; a worn or failed unit leaves the engine unable to start, taking equipment out of service entirely.
- Fits GXV270, GXV340, and GXV390 Engines — engineered specifically for Honda's vertical shaft engine series; verify your model and serial number against the compatibility table to confirm the correct assembly for your unit.
- Check Serial Number Before Ordering — Honda issues part supersessions at specific serial breaks within a model range, so matching your serial number to the fitment table is the surest way to get the right assembly the first time.
The starter motor assembly is the electric motor responsible for cranking the engine from rest to a speed at which combustion can begin. When the ignition key is turned to the start position, the assembly draws current from the battery, spins its pinion gear into mesh with the engine's ring gear, and rotates the crankshaft until the engine fires and takes over under its own power. Over time, brushes wear, armature windings degrade, or the pinion mechanism loses its ability to engage cleanly — any of which results in slow cranking, a grinding noise, or a complete failure to turn the engine over. Replacing the assembly with a genuine Honda unit restores the immediate, reliable cranking that GXV270, GXV340, and GXV390 vertical shaft engines depend on.
