Description
When your tractor starts blowing blue smoke, losing power, or burning oil faster than you’d like, worn piston rings are usually the culprit. This complete piston ring kit gives you everything needed to restore proper compression and seal those cylinders tight again, so you can get back to the work at hand.
What You’re Getting
- Complete ring set for all four cylinders—compression rings and oil control rings included
- Proper ring gap specifications designed for the Perkins T4.236 engine’s bore size
- Quality materials that handle the heat and pressure of diesel operation
- Direct replacement rings that fit without machine work in most cases
Built for Real Farm Work
This kit fits Massey Ferguson tractors across multiple series including the 300 series (390T, 398), 600 series (698T), and 3000 series (3065, 3070). These are solid workhorses you’ll find pulling implements, running loaders, and handling the daily chores that keep a farm running. The Perkins T4.236 is a proven four-cylinder diesel that’s been powering farm equipment for decades.
Made to Last
Piston rings take a beating from combustion pressure, heat cycles, and constant movement. These rings are built to handle those conditions with proper materials and heat treatment. They’ll restore compression, reduce oil consumption, and give you the power you remember when that tractor was newer.
Good to Know
Ring installation requires removing the pistons, so this is an engine-out job or at least a major teardown. Check your cylinder bore condition before installing new rings—if the cylinders are worn or scored, you’ll need machine work first. Take your time with ring gap measurements and follow proper installation procedures to get the best results.
