The Honda 16551-Z0G-000 Governor Arm is a genuine OEM replacement designed for F220 tillers and GXV50 and GXV57 vertical shaft engines. As a direct Honda OEM component, this part is manufactured to the same specifications as the original, ensuring a correct fit without modification. Confirm your machine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and multiple production runs may apply. This Governor Arm is the dependable choice when restoring proper engine speed control to your equipment.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this arm meets the exact dimensional and functional requirements of the original governor linkage, ensuring the governor system operates as intended.
- Correct Throttle Response — the governor arm is the mechanical link that translates governor shaft movement into throttle adjustments; a worn or bent arm produces erratic engine speed and poor load response.
- Broad Fitment — fits F220 tillers and GXV50 and GXV57 vertical shaft engines; verify your serial number against the fitment table to confirm the correct production range.
- Drop-In Replacement — matches the original mounting geometry, so this part installs directly onto the governor shaft without reworking the linkage.
The governor arm is a critical link in the mechanical governor system. It connects to the governor shaft and translates the shaft's rotational movement into linear movement at the throttle, automatically adjusting engine speed to maintain a steady rpm under changing loads. When the governor arm is bent, cracked, or worn at its connection points, the governor loses the ability to regulate throttle precisely — the result is hunting, surging, or an engine that runs at an uncontrolled speed. Replacing a damaged arm restores stable, responsive speed control and protects the engine from over-revving under light load conditions.
