Description
When your International Harvester tractor’s been running hard for years and compression starts dropping off, it’s time to pull those cylinders and see what’s going on. If you find the cylinder walls are scored or worn beyond the standard spec, don’t write that engine off yet. This .040 oversize rebore kit gives your old IH a fresh start with everything you need to bring compression back to like-new levels.
What You’re Getting
- Complete set for 4 cylinders – pistons, rings, pins and retainers all included
- TISCO quality construction that matches original specifications
- Oversize pistons that work with .040 rebored cylinders
- Ring sets designed specifically for International Harvester engines
Built for Real Farm Work
This kit’s designed for those dependable International Harvester 4-cylinder engines that have been the backbone of farming for decades. Whether you’ve got a utility tractor that’s been loader work or a row-crop machine that’s seen thousands of acres, these engines were built to last. When you rebore the cylinders and drop in this kit, you’re giving that engine another lease on life.
Made to Last
TISCO builds these components to handle the demands of agricultural work – constant temperature changes, dusty conditions, and the kind of steady running that farm tractors see. The pistons are engineered to work with modern oils while maintaining the tolerances your IH engine was designed for.
Good to Know
You’ll need to have your cylinders professionally bored .040 over before installing this kit. Make sure to check cylinder taper and out-of-round before boring – some blocks might need sleeves instead. Take your time with ring gap measurements and follow proper break-in procedures once you get her back together.
