When your John Deere's engine starts burning oil or you're seeing white smoke on startup, it's usually time to dig into the cylinders. Whether it's blow-by from worn rings or a scored liner from running a little low on coolant, this complete cylinder kit gets your turbo engine back to spec with everything you need in one package. What You're Getting Complete piston assembly engineered for turbocharged operation and higher pressures Precision-machined cylinder liner that restores proper bore dimensions and surface finish Full ring set including compression rings and oil control rings for proper sealing All components matched and tested together - no mixing and matching different brands Built for Real Farm Work These kits are designed for the workhorses of many farm operations - those reliable John Deere tractors that handle everything from heavy tillage to long days on the combine. The 4239T and 4039T engines power mid-size tractors perfect for general farm work, while the 6359T was found in larger machines built for serious acreage. Made to Last Turbocharged engines run hotter and see higher pressures than naturally aspirated versions, so the components have to be up to the task. This kit uses materials and manufacturing processes designed to handle the extra stress. The piston features reinforced ring lands and the proper crown design for turbocharged combustion. Installation Notes This is a professional-level rebuild job that requires engine teardown and proper measuring tools. Check your cylinder bore dimensions and crankshaft condition before ordering - a machine shop can verify everything's within spec. Having the cylinders honed to match the new liners ensures the best ring seal and longest life.
