Description

When your old IH tractor starts burning oil or you notice blue smoke on startup, it’s time to rebuild that trusty engine. Worn piston rings let combustion pressure and oil get where they shouldn’t be, robbing power and making you add oil every few hours of work. This complete ring set gives you everything you need to restore proper compression and get your tractor running like it should.

What You’re Getting

Complete set with 3 compression rings and 1 oil ring per cylinder
3/32 inch compression rings that seal combustion pressure tight
1/4 inch oil ring that controls lubrication without burning it
Precise 3-5/8 inch overbore sizing for rebuilt cylinders
Quality TISCO construction that meets OEM specifications

Built for Real Farm Work

This ring set is designed for International Harvester tractors that have been overbored during engine rebuilding. Whether you’re restoring a classic Farmall for the field or rebuilding a work tractor that’s been earning its keep for decades, these rings handle the heat, pressure, and constant operation that farm engines face every day.

Made to Last

TISCO builds these rings to handle the demanding conditions of agricultural work. The compression rings maintain proper sealing under high cylinder pressures while the oil ring controls lubrication without excessive consumption. Quality materials and precise manufacturing ensure these rings will give you years of reliable service.

Good to Know

This is an overbore ring set, so make sure your cylinders have been bored to 3-5/8 inches before ordering. Most machine shops can verify bore size and ring gap specifications. When installing, follow proper ring gap procedures and use a quality ring compressor to avoid breaking rings during piston installation. Each set does one complete engine.
