Description
Overview:
This Mechanical Governor Yoke is a genuine Villiers component designed for horizontal lightweight engines to control and stabilise engine speed under varying load. Made from durable pressed steel, it forms part of the governor linkage that adjusts throttle position to keep the engine running at a steady RPM. It is suitable for Villiers 125CC and 150CC engines, including models such as 512H and 515H. Supplied as unused new old stock (NOS), it may show light tarnish from storage, but remains fully serviceable. As an OEM part, it offers the correct geometry and fit to restore proper governor function, reduce speed hunting, and protect the engine from overspeed. Ideal for maintenance and period-correct restorations where reliability and compatibility matter.
Key Features:
- Genuine Villiers part for assured fit and compatibility (OEM 25891)
- Pressed steel construction for strength and long service life
- Restores smooth, consistent engine speed under load
- Direct replacement for worn, bent, or corroded yokes
- Suits horizontal lightweight engines in the 125CC and 150CC range
- Compatible with vintage models including 512H and 515H
- Unused NOS item; functionally sound with possible cosmetic ageing
- Simple to fit with standard hand tools; no modifications normally required
Typical Applications:
Used on Villiers horizontal engines powering equipment such as small generators, pumps, rotavators, compact mowers, and light construction machinery. Replaces a damaged or worn governor yoke to improve idle stability, maintain set operating speed, and prevent overspeed during load changes in workshop, site, or garden machinery.
