The Multiquip 16551Z4M000 is a genuine OEM Governor Arm designed for GA2.5HR, GAC2.5HR, MVC88VTH, MVC88VTHW, MVC82VH, MVC82VHW, and MVH128GH equipment. As a direct OEM replacement sourced through Multiquip's authorized parts program, this component is built to the exact specification of the original part it replaces. Whether you're servicing a plate compactor or a gasoline-powered generator, this Governor Arm restores precise engine speed control and keeps your equipment performing as intended.
Key Features
- Genuine OEM Construction — Manufactured to the same tolerances as the original Honda GX160UT2 engine component, ensuring correct mechanical engagement with the governor linkage.
- Direct-Fit Replacement — Mounts to the existing governor shaft and linkage points without modification, allowing a straightforward swap during engine servicing.
- Broad Multiquip Fitment — Compatible with GA2.5HR, GAC2.5HR, MVC88VTH, MVC88VTHW, MVC82VH, MVC82VHW, and MVH128GH models, covering both compactor and generator applications.
- Stable Engine Speed Regulation — A correctly functioning governor arm maintains consistent RPM under variable loads; a worn or bent arm causes erratic speed hunting, loss of compaction force, or unstable generator output.
- Verified Part Number — 16551Z4M000 cross-references directly to the Honda GX160UT2 engine family used across multiple Multiquip platforms, eliminating guesswork when ordering.
The governor arm is a mechanical link in the engine's speed-governing system, connecting the governor shaft to the throttle control linkage. Its job is to automatically adjust the throttle in response to changes in engine load, keeping the engine running at a steady, pre-set RPM. When the arm becomes bent, worn, or damaged, the governor loses its ability to modulate throttle position accurately — leading to engine surging, speed instability, or a machine that bogs down under load and fails to recover. Replacing a faulty governor arm promptly restores proper speed control and protects the engine from the stress of unregulated operation.
