Description
When your old International Harvester starts burning oil, knocking on startup, or just doesn’t have the power it used to, it’s probably time to give that engine a complete rebuild. This comprehensive overhaul kit has everything you need to bring your tractor back to like-new performance without hunting down individual parts or making multiple trips to town.
What You’re Getting
- Complete engine rebuild in one box—sleeves, pistons, rings, valves, gaskets, bearings, and all the hardware
- Tru-Power quality parts that meet or exceed original specifications for reliable performance
- Includes both .010 rod bearings and main bearings for proper clearances
- Stepped-head pistons designed specifically for the 123 CID engines
- Complete valve train components—intake and exhaust valves, springs, guides, and keepers
Built for Real Farm Work
This kit is designed for the 4-cylinder gas engines found in International Harvester’s workhorse tractors including the 100 series, 200 series, Super A-1, Super AV-1, and Super C models. These are the tractors that built America’s farms—reliable, simple machines that can handle everything from cultivating corn to running a hay baler.
Made to Last
Tru-Power has been building quality engine components for decades, and this kit uses the same materials and tolerances as the original factory parts. The cylinder sleeves are precision-machined for proper fit, the pistons are cast from high-grade aluminum, and all gaskets are made from materials that can handle the heat cycles and pressure of hard farm work.
Good to Know
This is a complete overhaul kit, so you’ll want to plan on having the block checked for cracks and the crankshaft inspected before you start. The kit includes standard bore components, but if your cylinders are worn beyond spec, you might need to go with the overbore option. Most experienced mechanics can handle this rebuild with basic shop tools, though you’ll want access to a torque wrench for proper assembly.
