Description
When you start hearing that telltale knock from under the hood or notice blue smoke puffing out the exhaust stack, worn piston rings are usually the culprit. These rings work harder than just about any part in your engine—sealing combustion pressure, controlling oil, and transferring heat from piston to cylinder wall thousands of times per minute. This three-ring set gets your 219 cubic inch diesel engine back to sealing tight and running clean.
What You’re Getting
- Complete three-ring set for one cylinder with keystone top compression ring that handles high combustion pressures
- Standard 4.02-inch bore size that fits like the original factory rings
- One 1/8-inch keystone compression ring, one 3/32-inch second compression ring, and one oil control ring at .196-inch
- Quality construction designed for the demanding conditions of agricultural diesel engines
- Direct replacement that installs with standard ring installation tools
Built for Real Farm Work
This ring set fits John Deere 20 and 30 series tractors with the 219 CID four-cylinder diesel engine, including models like the 2020, 2030, and 2120 that handle everything from loader work to field operations. These are the reliable workhorses you depend on for daily chores, hay work, and light tillage—tractors that need to start every morning and run all day without fuss.
Made to Last
Diesel engines are hard on rings, especially when you’re working in dusty conditions or pulling heavy loads. The keystone design on the top ring handles the extreme pressures and temperatures of diesel combustion better than straight-sided rings. The multi-piece oil control ring does a better job managing oil consumption, which means less mess and lower operating costs.
Good to Know
Installing rings requires proper ring gap measurement and careful handling—they break easily if you’re not careful. Use a quality ring compressor and check your cylinder bore condition before installation. If you’re doing one cylinder, it’s usually worth checking the others while you’re in there. Keep everything clean during assembly, and don’t forget to check your piston pin clearances while you’ve got things apart.
