Description
Overview:
Valve Spring Top Seats are precision steel components that sit at the top of the valve spring to keep it correctly located and loaded during engine operation. This genuine Villiers part is made for classic Villiers single-cylinder engines, including MK20 and MK25, and helps preserve correct valve timing and compression by maintaining spring alignment and tension. Finished in a durable dark protective coating, each top seat is built to cope with the heat, vibration and oil found in small air-cooled engines used on older garden and construction equipment. Supplied as unused old stock, these EM126 seats may show light tarnishing or storage marks, but this does not affect function. OEM reference: EM126. A straightforward replacement for worn or missing originals.
Key Features:
- Genuine Villiers part for assured fit and compatibility (OEM EM126)
- Durable steel construction for long service life in harsh engine environments
- Maintains correct valve spring tension and alignment for stable valve operation
- Helps protect valve train components by reducing spring wander and wear
- Dark protective finish offers basic corrosion resistance from storage and use
- Suitable for restoration and ongoing maintenance of vintage engines
- Direct like-for-like replacement with no modifications required in standard applications
- Supplied as unused old stock; cosmetic ageing only, fully functional
Typical Applications:
Used on Villiers MK20/MK25 stationary engines fitted to classic mowers, rotavators, compact generators, pumps and light construction equipment. Ideal when rebuilding cylinder heads, replacing fatigued valve gear, diagnosing valve noise or inconsistent compression, or completing authentic restorations where original-pattern hardware is preferred.
