Description

When your International Harvester tractor starts showing signs of worn rings—blue smoke at startup, oil consumption, or just not pulling like it used to—you know it’s time for fresh rings. This single cylinder piston ring set gets one cylinder back to proper compression and sealing, so you can tackle the job one cylinder at a time or replace just what needs fixing without doing a complete overhaul.

What You’re Getting

Complete ring set for one cylinder with two compression rings at 3/32 inch and one oil control ring at 3/16 inch
Proper ring spacing and tension designed specifically for 3.25 inch bore International Harvester engines
TISCO quality construction that handles the heat cycles and pressures of farm diesel work
Direct replacement sizing—no modifications needed for standard bore cylinders

Built for Real Farm Work

TISCO builds their piston rings to handle the harsh conditions inside diesel engines – high compression ratios, constant heat cycling, and the contaminants that come with farm work. These rings are manufactured to maintain proper tension and sealing through thousands of operating hours. Whether you’re running hay equipment, pulling implements, or operating a loader, proper ring sealing is what gives your tractor the power to handle tough jobs day after day.

Made to Last

International Harvester engines were built for the long haul, and these replacement rings match that durability. The ring materials resist wear from combustion heat and contamination while maintaining proper oil control and compression sealing. You’ll get the reliable performance your IH tractor was designed to deliver.

Installation Notes

Ring installation requires engine disassembly and proper measuring tools to ensure correct fit. Check your cylinder bore for wear or scoring before installing new rings – sometimes cylinders need honing for proper ring seating. If you’re doing the work yourself, take your time with ring gap measurements and make sure everything’s clean before assembly.
