Description
Overview:
This Piston Ring Set +020 is a genuine Villiers spare for the C12 single‐cylinder engine, used widely in vintage garden and light construction machinery. The rings are manufactured from durable materials to withstand heat, pressure, and friction inside the cylinder. Their job is to seal the combustion chamber, control oil, and maintain correct compression so the engine starts reliably and runs smoothly. The +0.020 inch oversize (+0.50 mm) ring set is intended for use in a cylinder that has been rebored by this amount and must be paired with a matching +0.020 inch (+0.50 mm) oversize piston. Supplied as an unused old stock item, it may show minor tarnish or storage marks that do not affect performance. Suitable for restoration and maintenance of the Villiers C12.
Key Features:
- Genuine Villiers part for correct fit and reliable performance
- +0.020 inch (+0.50 mm) oversize for properly rebored cylinders; use with matching oversize piston
- Restores compression and oil control for easier starting and stable running
- Durable construction to resist wear, heat, and blow‐by
- Precision‐made ring profiles for consistent sealing when installed and gapped correctly
- Helps reduce smoke and oil consumption when the bore and piston are in good condition
- Supplied as a ring set for one piston/cylinder
- Unused old stock; cosmetic ageing does not affect function
Typical Applications:
Engine rebuilds and repairs on Villiers C12 units found in vintage mowers, cultivators/rotavators, small pumps, generators, and light site equipment. Ideal when a cylinder has been rebored to +0.020 inch (+0.50 mm) and a matching oversize piston is fitted, to recover compression, reduce oil burn, and extend service life.
