Description

When your diesel tractor starts blowing blue smoke, burning oil, or just doesn’t have the pulling power it used to, worn piston rings are usually the culprit. This complete ring set gets your 4-cylinder engine breathing right again, sealing combustion pressure where it belongs and stopping oil from sneaking past into the combustion chamber. You’ll notice the difference right away—cleaner exhaust, better fuel economy, and that solid compression feeling when the engine fires up cold.

What You’re Getting

Complete 3-ring set per cylinder with keystone top ring for superior sealing under high compression
Precision-engineered ring gaps and tension designed specifically for 4.02-inch bore applications
Quality steel construction that handles the heat cycling and pressure of diesel operation
Direct replacement for 219 cubic inch 4-cylinder engines—no modifications needed

Built for Real Farm Work

This ring set is designed for the smaller 4-cylinder diesel engines that power compact and utility tractors used for hay operations, livestock work, and general farm duties. These engines see steady use in applications like brush hogging, loader work, and pulling smaller implements where reliable power matters more than raw horsepower.

Made to Last

Diesel engines run hot and work hard, and these rings are built to handle both. The keystone design of the top compression ring provides better sealing under pressure, while the oil control rings keep lubrication where it should be. Quality materials and proper heat treatment mean these rings maintain their tension and sealing properties through thousands of operating hours.

Good to Know

Ring installation requires complete engine disassembly and proper measuring tools—this isn’t a weekend driveway job. Check your cylinder bores for wear or scoring before installing new rings, as worn cylinders may need honing for proper ring seating. Take time to measure ring gaps properly and follow torque specifications during assembly. It’s also a good opportunity to check bearings, gaskets, and other wear items while you’re in there.
