Description
Overview:
These Valve Cotter Pins are genuine Villiers components designed for the Villiers BSA 65 cc Industrial Engine. Manufactured from hardened steel for strength and wear resistance, they lock into the groove on the valve stem and clamp within the spring retainer to hold the valve spring securely under load. By keeping the spring and valve correctly seated, they support smooth valve operation, reliable timing, and overall engine longevity in tough industrial use. Supplied as unused old stock, they may show superficial tarnishing or storage marks, but performance is unaffected. Marked to OEM reference 87 40, they offer a dependable, direct-fit solution for routine servicing or full top-end rebuilds on vintage Villiers/BSA industrial engines where correct fitment and material quality are essential.
