The Honda 16555-ZM0-000 Governor Rod is a genuine OEM replacement built for GCV160 and GCV190 vertical shaft engines and a wide range of Honda walk-behind lawn mowers, including the HRB216, HRB217, HRC216, HRR216, HRS216, HRT216, HRX217, and HRZ216. Sourced directly from Honda, this part matches the original specification exactly, so there is no guesswork on fit or function. Because Honda supersedes parts at serial breaks, verify your unit's serial number against the fitment table before ordering to confirm this is the correct rod for your machine.
Key Features
- Genuine Honda OEM — supplied by Honda to the same specification as the part that came out of the engine, ensuring the governor linkage operates exactly as designed
- Broad Fitment — covers GCV160 and GCV190 vertical shaft engines along with multiple HRB, HRC, HRR, HRS, HRT, HRX, and HRZ lawn mower models; see the fitment table to confirm your unit
- Serial Number Matters — Honda updates parts at production breaks, so cross-check your machine's serial number with the compatibility table to ensure part number 16555-ZM0-000 is the right match
- Engine Speed Stability — a correctly functioning governor rod keeps engine speed steady under changing load; a bent, worn, or missing rod allows the engine to surge, hunt, or run at uncontrolled speed
The Governor Rod is a mechanical link within the governor system that connects the governor arm to the throttle shaft. As engine load changes, the governor mechanism moves through this rod to adjust throttle position and hold the engine at a consistent operating speed. When the rod is bent, worn at its connection points, or broken, the governor loses its ability to modulate throttle response accurately — resulting in speed surging, hunting, or an engine that cannot hold a steady RPM under load.
