Description
Overview:
This Piston Ring Set +030 is a genuine Villiers component for the C12 engine, supplied under part number C12RS30. It replaces worn rings to restore cylinder sealing, improve compression, and control oil, helping the engine start reliably and run smoothly. The set is intended for engines that have been rebored to accept a +0.030 inch oversize piston (approximately +0.76 mm). Manufactured to the correct profiles for the C12, the rings are made from durable ring-grade iron to withstand heat, pressure, and bore wear in classic small engines. Suitable for vintage Villiers-powered machinery found in garden and light construction equipment, this unused old stock item may show minor storage marks but remains fit for service in C12 rebuilds and maintenance.
Key Features:
- Genuine Villiers part for assured compatibility with C12 engines
- Correct +0.030 inch oversize specification (approx. +0.76 mm) for rebored cylinders
- Restores compression and reduces blow-by for improved running and starting
- Oil control and sealing performance to help minimise smoke and oil consumption
- Durable ring-grade iron construction for heat and wear resistance
- Supplied as a matched set for one piston to maintain proper ring pack balance
- Straightforward fit for competent home mechanics or workshops with standard tools
- Suitable for use after a light hone; check ring end gap and groove clearance during install
- Unused old stock; may show light tarnish or shelf wear that does not affect function
- OEM reference C12RS30 for easy identification and parts matching
Typical Applications:
Used during overhaul or routine refresh of Villiers C12 engines in classic lawn mowers, rotavators, compact generators, small pumps, and light construction equipment. Ideal where the cylinder has been rebored to +0.030 inch (+0.76 mm) and a new oversize piston is fitted, to restore engine performance and service life.
