The Multiquip 16541Z4M000 is a genuine OEM Governor Arm Shaft designed for GX160UT2QMX2-equipped Multiquip equipment, including the GA2.5HR, GAC2.5HR, MVC88VTH, MVC88VTHW, MVC82VH, MVC82VHW, and MVH128GH. Sourced directly from Multiquip, this part meets the exact engineering specifications of the original component it replaces. If your governor system is showing signs of erratic engine speed, hunting, or loss of throttle control, this shaft is a critical part of the repair.
Key Features
- Genuine OEM Precision: — Manufactured to the exact dimensional tolerances required for correct governor arm travel and engine speed regulation on GX160UT2QMX2-powered machines.
- Direct Installation Fit: — Replaces the original shaft position-for-position within the governor arm assembly, connecting without modification to existing linkage components.
- Broad Model Coverage: — Confirmed fitment across GA2.5HR, GAC2.5HR, MVC88VTH, MVC88VTHW, MVC82VH, MVC82VHW, and MVH128GH.
- Consistent Engine Speed Control: — A correctly functioning governor arm shaft keeps the engine running at a stable, load-responsive RPM — a worn or bent shaft causes speed fluctuation that affects compaction force output and generator voltage stability.
- Fuel System Safety Relevance: — Because the governor directly controls fuel delivery rate under load, using the correct OEM shaft ensures the throttle response stays within designed operating limits and prevents over-speed conditions.
The governor arm shaft is a core mechanical link in the engine's speed-governing system. It transmits movement from the governor flyweights to the carburetor throttle, automatically adjusting fuel delivery to maintain a consistent engine RPM as load conditions change. When this shaft is worn, bent, or damaged, the governor loses its ability to make accurate corrections — resulting in engine hunting, surging, or runaway RPM that can damage the engine and reduce equipment output.
