This basic rebuild kit gives you the essential components to bring that 4239T turbocharged diesel back to life without breaking the bank on a complete overhaul. It's the practical choice when you need to get more years out of your investment.

Built for Real Farm Work
The 4239T is a workhorse engine found in many John Deere tractors from the 1980s and 1990s that are still earning their keep on farms today. Whether you're running a utility tractor for loader work or a row-crop machine for planting and cultivation, this turbocharged four-cylinder has the power and torque to handle demanding jobs when it's running right.
Made to Last
Farm engines work hard in dusty conditions with varying loads and long hours. These rebuild components are manufactured to handle the heat and pressure that comes with turbocharging while maintaining proper clearances for long service life. Quality materials and precise machining ensure your rebuilt engine will provide years of reliable operation.
Good to Know
Since this is a basic kit, you'll need to have your block and head work done separately—things like cylinder boring, valve work, and bearing sizing. Make sure to specify your bearing sizes when ordering since they're not returnable once the kit is built. It's worth having a machine shop measure everything before you place the order to avoid delays.
