The Honda 31217-ZF5-L31 Armature is a genuine OEM component designed for GXV340 and GXV390 vertical shaft engines. As a direct Honda OEM part, it is manufactured to the same specification as the original, ensuring a proper fit with no guesswork. This armature is the correct replacement for both the GXV340 and GXV390 — confirm your engine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks. Sourcing part number 31217-ZF5-L31 directly through an authorized Honda parts dealer means you get the exact component your engine calls for.
Key Features
- Genuine OEM Winding Integrity — wound and assembled to Honda's original specification, so electrical output and starter engagement characteristics match what the engine was built around
- Correct Fit for GXV340 and GXV390 Engines — engineered specifically for these vertical shaft engines, dropping in without modification
- Serial Number Verification Recommended — Honda updates part supersessions at defined serial breaks; check your engine's serial number against the fitment table to confirm part number 31217-ZF5-L31 is correct for your unit
- Restores Starter System Function — a failed armature prevents the starter motor from generating the torque needed to crank the engine; replacing it returns the system to full operation
The armature is the rotating core of the starter motor, made up of wound copper coils and an iron core mounted on the motor shaft. When the starter is engaged, current flows through the armature windings, generating the electromagnetic force that spins the shaft and turns the engine over. As the armature wears or fails — through worn commutator segments, shorted windings, or bearing wear — the starter motor loses cranking power or stops working entirely, leaving the engine unable to start. Replacing a worn armature with a genuine Honda part restores the starter motor's full output and ensures dependable engine starts on GXV340 and GXV390 vertical shaft engines.
