Built for Real Farm Work
This kit is designed for the International Harvester tractors that built the backbone of American agriculture—the 544, 574, 664, 674, and 684 series machines. These workhorses handled everything from cultivating corn to baling hay, and many are still earning their keep on farms today. Whether your tractor’s running a brush hog, pulling a grain drill, or handling loader work around the farmyard, this overhaul will get it back to reliable daily operation.
Made to Last
The Tru-Power components in this kit are built to handle the constant vibration, heat cycles, and heavy loads that farm engines endure. The cylinder sleeves provide a fresh bore surface while the complete gasket set ensures proper sealing between all mating surfaces. These aren’t cheap rebuild parts—they’re quality components designed to give you years of dependable service.
Installation Notes
This is a major engine rebuild that requires splitting the tractor and removing the engine from the frame. You’ll want to have your rod and main bearings checked by a machine shop while you’re at it, since they’re not included in this basic kit. Most folks have this work done by an experienced mechanic who can properly torque everything and ensure the timing is set correctly.
