Description
When your John Deere starts smoking, losing power, or burning more oil than you'd like, it's time to give that hard-working 4039 engine the rebuild it deserves. This complete basic engine kit gets you everything needed to bring your tractor back to strong, reliable performance without breaking the bank on individual parts. Whether you're tackling the rebuild yourself or having your mechanic handle it, having all the right parts in one package makes the job go smoother.

Built for Real Farm Work
The 4039 engine powers a wide range of John Deere tractors from compact utility models through mid-size field tractors. Whether you're running a 3400 around the farmyard, using a 5500 for hay operations, or operating one of the 6000 series tractors for row-crop work, this engine has proven itself reliable in agricultural applications where consistent power matters.
Made to Last
Tru-Power components are engineered to meet or exceed OEM specifications, giving you the durability and performance your operation demands. The pistons handle the compression loads, the rings seal properly for good power and fuel economy, and the gaskets keep everything where it belongs. These aren't budget parts that'll have you doing this job again in a few seasons.
Good to Know
This is a basic kit, so you'll need to source bearings separately based on your specific crankshaft measurements. Have your machinist check clearances and recommend the right bearing sizes before starting assembly. Take time to clean everything thoroughly—old carbon and debris can ruin new parts fast. A proper engine rebuild is an investment in years of reliable service ahead.
