Description
When your trusty International Harvester starts showing signs of wear—blue smoke out the exhaust, loss of power under load, or oil consumption that’s got you checking the dipstick daily—it’s time for a complete engine rebuild. This comprehensive overhaul kit gives you everything you need to bring that classic IH engine back to life and get years more service out of your tractor.
What You’re Getting
- Complete rebuild kit with high-compression stepped-head pistons for better power and fuel efficiency
- New sleeves and seals that restore proper cylinder bore and prevent oil leaks

- Full gasket set ensures proper sealing throughout the entire engine rebuild

Built for Classic Farm Work
This kit fits the reliable H Series, HV Series, and early O4, OS4, and W4 Series International Harvester tractors that were the backbone of American agriculture for decades. Whether you’re running a classic H for lighter farm duties, or rebuilding an O4 for orchard work, this engine kit restores the dependable power these machines were known for.
Made to Last
Tru-Power components meet or exceed original factory specifications, using materials designed to handle the constant load cycling of farm work. The stepped-head pistons provide the high compression ratio these gas engines need for proper power output, while the complete valve train components ensure smooth operation for seasons to come.
Good to Know
This is a complete teardown and rebuild job that requires proper machine shop work for boring, honing, and valve seat work. Most folks have the machine work done professionally while handling the reassembly themselves. Don’t forget to order your main and rod bearings separately—they’re not included in this kit but are essential for completing the rebuild.
