Key Features

• Genuine OEM Precision — Manufactured to Multiquip's exact tolerances for the governor arm, ensuring correct throttle response and engine speed regulation on AR13 series rollers.
• Direct Drop-In Installation — Matches the original mounting points and linkage geometry of the AR13HA/HAR, AR13H, and AR13HC, connecting directly to the existing governor linkage without alteration.
• Confirmed AR13 Series Fitment — Verified for AR13HA/HAR, AR13H, and AR13HC asphalt ride-on roller models.
• Consistent Engine Speed Control — A correctly functioning governor arm maintains stable engine RPM under varying load conditions, which is critical for smooth, even compaction passes on asphalt surfaces.
• Fuel System Integrity — A worn or failed governor arm can cause engine surging, hunting, or over-revving; replacing it promptly protects the engine from irregular fuel delivery and excessive wear.

The governor arm is a key mechanical link in the engine's speed-regulating system. It connects the governor shaft to the carburetor throttle, translating changes in engine load into throttle adjustments that hold RPM steady. When the governor arm wears, bends, or loses its connection, the engine loses the ability to self-regulate — resulting in surging, stalling, or runaway RPM that can damage internal engine components and compromise compaction quality. Keeping this component in good condition is essential to consistent, controlled roller operation.
