When your John Deere's engine starts showing signs of wear—low compression, oil consumption, or reduced power—it's time for a rebuild. This cylinder kit gives you everything needed to restore one cylinder back to factory specifications. Built with the precision these engines deserve, it includes a piston, liner, rings, and even the high ring for complete cylinder restoration. What You're Getting Complete cylinder assembly with piston, liner, and all rings included—no hunting for separate parts High-quality components that match factory specifications for reliable performance 106.5mm bore size and 35mm gudgeon pin for precise fit on 4239D and 6359D engines Standard compression height piston for proper engine balance and power delivery Built for Real Farm Work This kit is designed for the heavy-duty 4239D and 6359D diesel engines found in John Deere's workhorse tractors from the 30s through the 50 series. These engines powered everything from utility tractors to row-crop machines, handling daily chores like cultivation, planting, and hauling. Whether you're running a 2130 on smaller acreage or pushing a 3350 through heavy field work, these engines need quality parts that can handle the demands. Made to Last Each component is manufactured to meet the exacting standards these engines were designed with. The piston rings provide proper seal and oil control, while the cylinder liner is engineered to handle the thermal stress and pressure cycles of diesel operation. You're getting the same quality that made these John Deere engines legendary for their durability. Installation Notes This is a standard rebuild kit that requires proper engine work—cylinder boring, honing, and precise measurements are essential for success. Most experienced mechanics can handle the installation, but having the cylinder professionally bored and fitted is money well spent. Remember to check rod bearings and crankshaft condition while you're in there—it's the perfect time for a complete overhaul.
