Description

When you’re rebuilding that reliable 202 cubic inch diesel engine in your vintage John Deere tractor, getting the right piston rings is critical for bringing compression back to spec. If you’ve noticed blue smoke at startup or during work, weak power, or higher oil consumption, worn piston rings are often the culprit. This complete ring set gives you everything needed to seal one cylinder properly and get your engine running strong again.

What You’re Getting

Complete set with two compression rings at 3/32 inch thickness for proper sealing
One oil control ring at .196 inch thickness to manage oil consumption
Standard 3.86 inch bore size—perfect for engines that haven’t been overbored
High-quality construction that meets or exceeds original specifications

Built for Proven John Deere Power

This ring set is specifically designed for the 202 CID 4-cylinder diesel engines found in many classic John Deere tractors. These engines powered a wide range of utility and row-crop tractors that were the workhorses of farms across the country, handling everything from cultivation and planting to hay operations and general farm duties.

Made to Last

These rings are built to handle the heat, pressure, and constant cycling that diesel engines dish out. The compression rings seal combustion pressure while the oil ring controls lubrication, ensuring your rebuilt engine will deliver years of reliable service in demanding farm conditions.

Installation Notes

This is a single-cylinder set, so you’ll need four sets for a complete engine rebuild. Make sure your engine block matches one of the specified numbers: T23406, T24961, or T26933. During installation, use a quality ring compressor and take your time—proper ring gap measurement and careful installation prevents comeback problems down the road.
