When your old International Harvester tractor starts blowing a bit of smoke or burning more oil than usual, chances are it’s time for fresh piston rings. This ring set gets your engine breathing properly again, restoring compression and putting the power back where it belongs—turning the wheels instead of creating blue smoke clouds behind you.
What You’re Getting
- Complete 3-ring set for one cylinder with 3-11/16″ standard bore sizing
- Two compression rings at 1/8″ thickness with the top ring featuring a half keystone design for better sealing
- One oil control ring at 1/4″ thickness to keep oil where it should be
- Quality TISCO construction that meets OEM specifications and durability standards
- Precision-manufactured rings that seat properly and last through years of hard work
Built for Real Farm Work
This ring set fits International Harvester tractors equipped with engines using the 3-11/16″ bore configuration. These were common in various IH tractor models that spent their days pulling plows, running balers, and handling the countless jobs that keep a farm operation running. Whether you’re rebuilding an engine or just freshening up the top end, these rings are designed to handle the demands of agricultural work.
Made to Last
TISCO has built a solid reputation making reliable aftermarket parts that hold up to farm conditions. These rings are manufactured to precise tolerances and use materials that can handle the heat, pressure, and constant cycling of a working tractor engine. The half keystone top ring design helps prevent ring flutter at higher RPMs while maintaining a tight seal.
Installation Notes
These are direct replacement rings that install just like the originals. Make sure to check your cylinder bore dimensions and condition before installation—rings can only do so much if the cylinder walls are worn beyond spec. A quick tip: when installing, pay attention to the orientation markings on the rings and stagger the ring gaps around the piston for the best seal.
