Description
Overview:
Valve Collars for Villiers C12 Engine (OEM EM515) are Genuine Villiers parts designed to secure the valve stem to the spring retainer, keeping the valve train correctly located under load. Manufactured from durable steel with a precise machined profile, they provide a reliable lock between the valve and spring assembly. These collars suit classic Villiers small petrol engines used in garden and light construction machinery, including the C12 and MK10. As unused old-stock vintage items, they are functional replacements that may show minor tarnishing from age without affecting performance. They are intended for straightforward fitting during a top-end service, helping restore correct valve operation, prevent valve float, and maintain compression and timing stability in everyday use or restoration work.

- Precision seating faces for positive grip on the valve stem

Typical Applications:
Used during cylinder head overhauls, valve replacements, and routine top-end services on Villiers engines powering mowers, cultivators, generators, pumps, and other small plant.
