Description
When your 404 CID diesel starts showing signs of wear—burning oil on startup, losing power under load, or blowing blue smoke when you’re working hard—it’s telling you those cylinders and pistons need attention. This comprehensive sleeve and piston kit gets you back to pulling strong without the expense and downtime of a complete engine rebuild. Everything you need is here in one box to restore that reliable International Harvester power.
What You’re Getting
- Complete set of precision-fit sleeves and 3-ring pistons for all six cylinders
- All piston rings, wrist pins, and retainers needed for proper assembly
- Standard 4-1/4 inch bore components engineered for the 404 CID engine
- Quality components that meet original specifications for reliable performance
Built for Real Farm Work
This kit is designed for International Harvester tractors equipped with the 404 CID six-cylinder diesel engine, typically found in larger utility and row-crop machines from the era when farms needed serious power for heavy field operations. Whether you’re pulling deep tillage equipment, running heavy harvest machinery, or powering large implements, these engines were built to handle the demanding work that keeps farms productive.
Made to Last
The sleeve and piston components in this kit are built to handle the high compression and demanding conditions of diesel operation. The cast iron sleeves provide proper cylinder sealing while the three-ring piston design ensures optimal compression and oil control. These aren’t shortcuts—they’re the same quality components that made these engines legendary for durability.
Installation Notes
This is an in-frame rebuild kit, which means you can do the work with the engine still in the tractor. You’ll need to remove the head and oil pan, but the block stays put. Take time to check cylinder bore condition and measure everything properly before assembly—doing it right the first time saves headaches later. If your crankshaft bearings show wear, you’ll want to order those separately while you’ve got everything apart.
