Description

When your tractor’s running rough and burning oil, it’s usually the cylinders telling you they need attention. High-hour engines develop wear that lets oil slip past the pistons, and before you know it, you’re adding oil more than fuel. This complete rebore kit gives your 4.4-inch diesel engine a fresh start with everything you need to restore proper compression and power.

What You’re Getting

Four precision sleeves that restore your cylinders to like-new condition
Four pistons engineered to handle the heat and pressure of diesel combustion
Complete ring set that seals tight and controls oil properly
All components work together as a matched system for reliable performance

Built for Hard-Working Diesel Engines

This kit is designed for 4-cylinder diesel engines with 4.4-inch bore and 256 cubic inch displacement. These are the workhorses found in mid-size Ford tractors that handle everything from loader work to field cultivation. Whether you’re running a hay operation or doing general farm work, this engine size delivers the torque you need without drinking fuel like the bigger motors.

Made to Last

TISCO builds these kits to handle the unique demands of diesel engines. The sleeves are cast iron that expands and contracts properly with temperature changes, while the pistons are designed for the higher compression ratios diesels need. The ring sets provide the right tension to control oil consumption without creating excessive friction that robs power.

Good to Know

This is a complete engine teardown job that requires machine shop work for proper installation. It’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. Take your time with the break-in period—these engines respond well to careful running-in procedures.
