Description
When your International Harvester’s 239 diesel starts burning oil, knocking under load, or just doesn’t have the power it used to, it’s likely time for an in-frame rebuild. Instead of pulling the whole engine, this basic kit gives you everything you need to get your tractor back to running strong without the downtime of a complete overhaul.
What You’re Getting
- Complete cylinder sleeve and seal set to restore proper bore dimensions
- Cupped-head pistons with rings, pins and retainers for reliable compression
- Valve-grind gasket set to seal everything up tight when you freshen the head
- Oil pan gasket to prevent those annoying leaks under the tractor
- Quality Tru-Power components engineered to meet original specifications
Built for Real Farm Work
This kit fits the workhorses of many farm operations – the 544, 574, 664, 674, 684, and 2544 series International Harvester tractors. These are the machines that handle everything from cultivating and planting to hay work and loader duty. The 239 cubic inch diesel with its 3-7/8 inch bore was built for dependability, and this kit helps you restore that reliability.
Made to Last
Tru-Power has been rebuilding farm engines for decades, so they know what it takes to handle the demands of agricultural work. The sleeves are precision-machined to restore proper clearances, while the cupped-head pistons are designed to handle the heat cycles and pressures of diesel combustion. Quality materials mean this rebuild will give you years of reliable service.
Good to Know
This is a basic in-frame kit, so you’ll need to source bearings separately if yours need replacing. It’s designed for standard bore engines, and you’ll want to have your cylinders checked for wear before starting. Most farmers tackle this job during winter downtime when the tractor’s not needed in the field.
