Description
Overview:
The Piston Ring Set (3 Rings) 040 for Villiers F17 169CC engines is a genuine Villiers replacement designed to restore compression and oil control in classic single-cylinder petrol engines. Manufactured from quality cast iron and precision-ground for accurate seating, the set comprises the top compression ring, second ring and oil-control ring for a complete refresh of the piston sealing system. Sized for a 70 mm bore (approximately 2.76 in), this set is the 040 oversize specification, meaning it suits cylinders that have been rebored by +0.040 in (+1.02 mm). It is ideal for maintaining or rebuilding Villiers F17 and F17 169CC engines used in vintage machinery, ensuring reliable starting, steadier idle, and consistent power output.

Typical Applications:
