Description

When your John Deere diesel starts burning oil, losing power, or blowing blue smoke out the stack, it’s telling you the pistons and sleeves have seen better days. These reliable engines are workhorses that can run for thousands of hours, but eventually everything wears out. This complete kit gives you everything you need to bring that engine back to like-new performance without hunting down dozens of separate parts.

What You’re Getting

Complete sleeve and piston assemblies with 4-1/4 inch bore for proper cylinder sealing
Three-ring pistons that provide excellent compression and oil control in diesel applications

TISCO quality construction built to handle the demands of agricultural work
One kit services either 381 CID or 404 CID six-cylinder diesel engines depending on your block configuration

Built for Real Farm Work

This kit fits those dependable John Deere six-cylinder diesels that power everything from utility tractors to larger row-crop machines. Whether you’re running a loader all day, pulling heavy implements through tough ground, or putting in long hours during harvest, these engines were built to work hard. The 381 and 404 cubic inch displacement engines have been the backbone of many farm operations for decades.

Made to Last

Every component in this kit meets or exceeds original specifications. The TISCO brand has been trusted by farmers for decades, and they understand what it takes to handle the constant vibration and temperature cycles of tractor work. The sleeves are designed to handle the heat and pressure of diesel combustion while the pistons maintain proper ring seal for years of reliable service.

Good to Know

This is a complete teardown job that’s perfect for winter shop time when the tractor’s not needed daily. You’ll want to have the block and head professionally cleaned and checked for cracks before assembly. Make sure to verify your engine block numbers match the kit specifications—some blocks require different configurations even within the same displacement range.
