Description
When your engine starts using oil or losing compression, worn piston rings are usually the culprit. Instead of burning fuel efficiently, you’re burning oil and losing power with every stroke. This complete piston ring set gets your 6-cylinder diesel breathing properly again, restoring the compression and power your tractor needs for heavy field work.
What You’re Getting
- Complete 3-ring set per cylinder with keystone compression ring for maximum sealing
- Precision-fitted 4.19″ bore rings designed specifically for your engine
- Quality materials that handle the heat and pressure of diesel operation
- Direct replacement rings that install without machine shop work
Built for Real Farm Work
This ring set fits both the 359 CID naturally aspirated and 414 CID turbocharged 6-cylinder diesel engines found in John Deere tractors. Whether you’re running a loader tractor around the farmyard or pulling heavy implements in the field, these engines power some of the most versatile machines in agriculture. The turbocharged 414 CID version delivers extra power for the toughest jobs while maintaining the reliability farmers depend on.
Made to Last
Diesel engines run hot and hard, and piston rings take the brunt of that abuse. This set uses materials engineered to handle the extreme temperatures and pressures of modern diesel operation. The keystone design on the top compression ring provides superior sealing while resisting ring flutter at high RPMs.
Good to Know
Ring installation requires removing pistons from the engine, so this is typically part of a major overhaul. If you’re doing the work yourself, use a proper ring compressor and check ring end gaps before installation. Take your time with ring orientation—the keystone ring has a specific up direction that’s critical for proper sealing.
