Multiquip 16551 Governor Arm

The Multiquip 16551 Governor Arm is a genuine OEM component designed for a wide range of Multiquip, Whiteman, and Essick equipment including plate compactors, generators, mixers, saws, rollers, pumps, and walk-behind trowels. As a direct OEM replacement sourced through authorized channels, part 16551 is built to the exact specifications of the original, ensuring proper governor linkage operation across compatible models such as GAC2.2HZ, MVH158GH, MVC82VHW, SP1G, WM70S/P, and AR13H series equipment. DHS Equipment stocks genuine Multiquip parts so you can get the right component the first time without guesswork.

Key Features

• Genuine OEM Construction: — Manufactured to the original design tolerances, ensuring the governor arm delivers consistent throttle linkage travel and accurate engine speed control across all compatible machines.
• Drop-In Replacement: — Mounts to the existing governor linkage points using the original hardware, making it a straightforward swap without reworking surrounding components.
• Broad Equipment Compatibility: — Fits a wide range of Multiquip equipment families including plate compactors (MVH, MVC, MVB series), generators (GAC series), walk-behind rollers, concrete and mortar mixers, masonry saws, trash and centrifugal pumps, and walk-behind trowels.
• Engine Speed Stability: — A correctly functioning governor arm maintains steady RPM under varying load conditions, protecting the engine from over-revving and ensuring the machine delivers consistent output power.
• Fuel System Safety Relevance: — Because the governor arm directly controls fuel delivery rate, a worn or bent arm can cause uncontrolled engine acceleration or stalling — replacing it with a genuine part restores safe throttle response.

The governor arm is a mechanical linkage component that connects the engine's centrifugal governor to the carburetor throttle, controlling engine speed in response to load changes. When the load on the machine increases, the governor senses the drop in RPM and the arm opens the throttle to compensate; when the load drops, it closes the throttle to prevent over-speeding. A worn, bent, or broken governor arm disrupts this balance, leading to erratic engine speed, excessive fuel consumption, or engine damage — making timely replacement essential to keeping equipment running safely and efficiently.
