Description

When your tractor starts burning oil, losing compression, or just doesn’t have the power it used to, it’s often time to look at those piston rings. These Ford New Holland diesel engines with their 4.4 inch standard bore are workhorses that’ve been pulling implements and running PTOs for decades, but even the toughest engine eventually needs fresh rings to seal things up tight. This .030 overbore ring set gets your engine back to running like it should, with proper compression and oil control that’ll have you back in the field with confidence.

What You’re Getting

Complete ring set with three 3/32 inch compression rings and one 3/16 inch oil control ring per piston
Precision-ground .030 overbore sizing fits cylinders that have been properly bored and honed
Quality construction designed to handle the heat and pressure of diesel operation
Direct replacement rings that restore proper sealing and compression ratios

Built for Real Farm Work

These rings fit the 201 CID three-cylinder and 256 CID four-cylinder diesel engines found in a wide range of Ford tractors from utility models to larger farm tractors. Whether you’re running a 4000 series for loader work, a 5000 for hay operations, or a 6000 series for row crop farming, these engines have powered countless hours of field work, barn chores, and transport duties across farms everywhere.

Made to Last

Diesel engines run hot and work hard, especially when you’re pushing through tough ground or pulling heavy implements. These rings are built with the right materials and tolerances to handle the constant heat cycling, high compression ratios, and demanding service that farm tractors see every day.

Installation Notes

This is a .030 overbore set, so your cylinders need to be properly machined before installation. Most farm shops can handle the boring and honing work, but make sure they’ve got experience with these engines. When installing, take your time with ring gaps and use proper ring compressors—rushing this job usually means doing it twice.
