This isn’t just another band-aid repair—it’s everything you need to bring that 436 cubic inch workhorse back to running like new.

Built for Real Farm Work

This kit is designed for the 436 CID diesel engines found in International Harvester and Case IH tractors from the 1460 through 6388 series. These are the machines that handle the heavy lifting—combining, deep tillage, and long days pulling big implements. The 4.3-inch bore and robust design made these engines the backbone of commercial farming operations for decades.

Made to Last

Farm engines take a beating, and this kit is built to match the original factory specifications that made these powerplants so reliable. The sleeves are precision-machined to handle the thermal stress of diesel combustion, while the bearings are manufactured to withstand the demands of modern farming operations.

Good to Know

You’ll need to specify your bearing sizes when ordering—standard, .010, .020, .030, or .040 oversize depending on your crank’s condition. Take time to have your block and crank properly measured before starting the job. A good machine shop can tell you exactly what bearing sizes you’ll need and ensure everything’s within spec for a successful rebuild.
