Description

When your IH tractor starts burning oil or you notice white smoke on startup, chances are it’s time for a piston ring replacement. Worn rings let combustion pressure slip past the pistons and allow oil to sneak into the combustion chamber—problems that’ll only get worse if you put off the fix. This .040″ oversize ring set gives your engine the tight seal it needs to run clean and strong again.

What You’re Getting

Complete set of precision-made rings sized .040″ over standard bore
Top compression ring, second compression ring, and oil control ring for each cylinder
Quality construction that meets or exceeds original specifications
Proper ring gap and tension for reliable sealing and long service life

Built for Real Farm Work

This ring set is designed for International Harvester tractors that have had their cylinders bored .040″ oversize during an engine rebuild. Whether you’re overhauling the engine in your utility tractor or bringing a classic Farmall back to life, these rings are built to handle the demands of farm work—from PTO operations to heavy field work.

Made to Last

TISCO builds these rings to strict tolerances using quality materials that can handle the heat and pressure inside your engine. The proper metallurgy and surface treatments ensure good cylinder wall sealing while resisting wear from dirt and debris that finds its way into farm tractor engines.

Installation Notes

These rings require cylinders that have been professionally bored and honed to .040″ oversize. Make sure you have the right ring compressor tool and check your ring end gaps before installation. A good machine shop can verify your bore size and finish if you’re not sure about the cylinder preparation.
