Key Features
- Genuine OEM Precision: — Cast and machined to exact OEM tolerances, ensuring the governor arm engages the throttle linkage correctly on GX100-powered rammers.
- Direct Swap Installation: — Mounts to the original pivot point on the GX100 engine without modification, matching the factory hole pattern and arm geometry.
- Confirmed Rammer Fitment: — Verified for MTX70HF, MTX60HF, and MTR40HF Multiquip rammers equipped with the Honda GX100 float-carburetor engine.
- Consistent Engine Speed Control: — A correctly functioning governor arm keeps the GX100 running at stable RPM under load; a worn or bent arm causes erratic engine speed and poor compaction output.
- Authentic Multiquip Part Number: — Part number 16550Z0DV21 matches Multiquip's official parts catalog, so you can cross-reference with your machine's documentation before purchasing.
The governor arm is a mechanical linkage component that connects the engine's centrifugal governor assembly to the carburetor throttle. As engine load increases or decreases during operation, the governor detects the change in speed and moves the arm to open or close the throttle accordingly, keeping the engine running at a consistent target RPM. When the governor arm is bent, worn at its pivot, or broken, the engine loses the ability to self-regulate — resulting in hunting, stalling under load, or uncontrolled over-revving that can cause further engine damage.
