Description

When your Ford tractor starts burning oil or losing compression, worn piston rings are usually the culprit. This complete ring set gives you everything needed to restore proper sealing in your 172 CID gas engine’s 3.9-inch cylinders—two compression rings and one oil control ring per cylinder, just like it came from the factory.

What You’re Getting

Chrome-plated top compression rings for long-lasting wear resistance against combustion heat
Second compression rings designed to work perfectly with the chrome tops for optimal sealing
Oil control rings with proper tension to manage oil consumption without causing blow-by
Precision-ground ring gaps that ensure proper compression without binding in the cylinder

Built for Real Farm Work

This ring set fits Ford tractors with the 172 CID, 4-cylinder gas engine using 3.9-inch standard bore cylinders. These engines power a variety of Ford utility and row-crop tractors that handle everything from loader work to hay production. When properly installed, these rings restore the compression and oil control that keeps your tractor running strong through long days in the field.

Made to Last

The chrome top ring coating resists scuffing and wear from combustion heat, while the carefully designed oil control rings manage lubrication without letting oil slip past into the combustion chamber. This combination gives you the durability needed for farm work while maintaining proper compression for good fuel economy and power.

Installation Notes

Make sure to check your cylinder bore condition before installing new rings—worn cylinders might need honing or sleeves for proper sealing. Set the ring gaps according to your service manual, and take your time during installation to avoid breaking these precision parts. A ring compressor tool makes the job much easier and reduces the chance of damage.
