When you’re rebuilding that International Harvester engine and the cylinders need to be bored out, you’ll need these .020 oversize piston rings to get things back to factory compression. Whether it’s blow-by, oil consumption, or just time for a refresh after years of hard work, this ring set gets your single cylinder sealed up tight and ready for another season.
What You’re Getting
- Complete ring set for one cylinder with .020 inch oversize dimensions
- Cast iron construction that seats properly and maintains compression
- Includes compression rings and oil control ring for complete sealing
- Precision-manufactured to restore proper cylinder seal after reboring
Built for Real Farm Work
This ring set is designed for International Harvester 4-cylinder engines that have been rebored to .020 oversize. These are the same rings you’ll find in complete piston and ring kits used in engine rebuilds on tractors that have seen years of field work, hay making, and heavy pulling.
Made to Last
TISCO builds these rings to handle the heat, pressure, and constant wear that comes with farm engine operation. The materials and tolerances are engineered to provide proper sealing while allowing for the thermal expansion that happens when engines get up to operating temperature under load.
Installation Notes
These rings are sized for cylinders that have been professionally rebored to .020 oversize – they won’t fit standard bore cylinders. Make sure your machine shop has honed the cylinders to proper finish and verified the bore size before installation. Take your time gapping the rings according to your engine manual for best results.
