Description
Overview:
These cylinder base studs are genuine Villiers fasteners for securing the cylinder barrel to the crankcase on classic small engines, notably the Villiers MK20 and MK25. Manufactured in durable steel for strength and stability, they hold the cylinder base square and maintain correct clamping force around the base gasket, helping to prevent leaks and loss of compression. Supplied as vintage stock, the surface may show age-related tarnish or storage marks, but performance is unaffected. They are suited to restoration, routine maintenance, and full rebuilds of vintage Villiers-powered garden and construction machinery where reliability matters. Marked to OEM reference EM238, these studs provide the correct fit and alignment for the intended engines, supporting consistent torqueing and dependable service life when installed to the workshop manual.
Key Features:
- Genuine Villiers part for assured compatibility and quality (OEM EM238)
- Steel construction for strong, reliable clamping of the cylinder base
- Correct form and length for precise seating and gasket integrity on MK20/MK25
- Stable joint under heat and vibration typical of small air-cooled engines
- Suitable for rebuilds, gasket replacement, or routine top-end servicing
- Vintage stock: finish may be tarnished; functionality remains sound
- Helps maintain compression and reduces risk of base gasket weep
- Straightforward installation using standard workshop methods and tooling
Typical Applications:
Used during engine overhauls, cylinder removal and refitting, base gasket changes, and restoration of vintage Villiers engines in equipment such as mowers, rotavators, generators, light construction machinery, and pumps. Ideal where the original studs are missing, stretched, damaged, or corroded, ensuring the cylinder is secured evenly to maintain reliable running.
