The Honda 16541-ZA0-700 Governor Arm Shaft is a genuine OEM component designed for GX360 horizontal shaft engines, EV4010, EV6010, and EVD4010 RV generators, and H4514, HT3813, and HT4213 lawn tractors. As a direct OEM replacement, this shaft restores the mechanical governor linkage to Honda's original specification, keeping engine speed controlled and stable under load. Confirm your model and serial number against the fitment table before ordering — Honda supersedes parts at serial breaks, and this shaft must match your unit's build exactly.
Key Features
- Genuine OEM Governor Linkage Precision — sourced directly from Honda, this shaft carries the exact diameter, length, and pivot geometry the governor arm depends on for accurate throttle response and consistent speed control
- Direct OEM Replacement — fits the original mounting points with no alteration required, restoring the mechanical governor linkage to as-built condition
- Broad Fitment Across Honda Equipment — covers GX360 horizontal shaft engines, EV4010, EV6010, and EVD4010 RV generators, and H4514, HT3813, and HT4213 lawn tractors, including a range of serial breaks within each model
- Verify Your Serial Number — Honda updates part supersessions at production breaks; cross-check your machine's serial number against the compatibility table to confirm this is the correct shaft for your unit
- Restores Speed Stability — a worn or damaged governor arm shaft allows slop in the linkage, causing engine speed to hunt, surge, or fail to hold under changing load conditions; replacing it returns steady governed operation
The governor arm shaft is the pivot pin at the heart of Honda's mechanical governor system. It anchors the governor arm to the engine or equipment housing, translating the flyweight assembly's movement into throttle correction — opening or closing the carburetor to hold a steady rpm as load changes. When this shaft wears, bends, or develops play, the linkage loses its reference point: the engine begins to hunt for its set speed, surges under load, or runs away when load drops. Replacing the shaft with a genuine Honda part restores the tight pivot geometry the governor system relies on for smooth, stable speed regulation.
