The Honda 16546-ZG5-L00 Governor Arm Shaft Collar is a genuine OEM component designed for EB12 generators and H6522 compact tractors.

Key Features
- Genuine Honda OEM — manufactured to Honda's original specification, ensuring the collar seats and retains the governor arm shaft exactly as the engine was built to require.
- Governor System Integrity — a correctly fitted collar keeps the governor arm shaft properly positioned, maintaining consistent throttle response and engine speed control under load.
- Broad Equipment Coverage — fits EB12 generators and H6522 compact tractors; check your serial number against the fitment table to confirm applicability to your specific unit.
The governor arm shaft collar is a small but essential retention component in the mechanical governor assembly. It locates the governor arm shaft axially, keeping the arm in the correct position so the governor can accurately sense engine speed and adjust the throttle to maintain steady power output. When this collar is worn, missing, or damaged, the governor arm can shift out of position, leading to erratic engine speed, hunting, or an inability to hold a set RPM under varying loads.
