Restore the powerhouse performance of your late-model John Deere® 4840 or 8440 with this remanufactured 466T crank-drive long block assembly. Designed specifically for tractors equipped with a crankshaft-driven injection pump, this turbocharged 6-cylinder diesel rebuild delivers the torque, reliability, and field-proven performance your machine was built to handle—whether you're running row crop or 4WD articulated equipment.
This remanufactured long block features a fully machined block, reground crankshaft, rebuilt cylinder head, and new pistons, sleeves, connecting rods, camshaft, and timing components.

With the correct fuel timing geometry and reinforced internals, this long block is built for extended service under heavy PTO loads, deep tillage, and high-drawbar applications.
Each unit is carefully inspected and assembled to OEM tolerances, ensuring consistent quality and durability you can trust. Backed by a 1-year warranty and supported by a knowledgeable parts team, this reman 466T long block helps you avoid costly downtime and extends the working life of your equipment—without sacrificing performance.
