Description
When your old gas engine starts blowing smoke past the rings or just doesn’t have the compression it used to, fresh piston rings can bring it back to life. This complete set gives you everything needed for one cylinder of your 135 cubic inch 3-cylinder gas engine, getting each piston sealed up tight so you can get back to reliable operation.
What You’re Getting
- Complete ring set designed specifically for 3.86″ bore cylinders
- Two compression rings at 3/32″ thickness for proper sealing
- One oil control ring at .196″ to manage lubrication
- Quality construction that handles the heat and pressure of gas engine operation
Built for Real Farm Work
This ring set fits the reliable 135 CID 3-cylinder gas engines that powered countless John Deere tractors through their early years. These were the workhorses before diesel became king, handling everything from cultivating to hay work with dependable performance when properly maintained.
Made to Last
Gas engines run different than diesels, with higher RPMs and different combustion characteristics that demand rings engineered for the job. These rings are built to handle the thermal cycling and cylinder pressures that come with gas engine operation, maintaining proper seal for years of reliable service.
Good to Know
When you’re doing rings, it’s the perfect time to check cylinder bore condition and piston clearances. If you’re rebuilding multiple cylinders, order enough sets to do them all at once. Check your serial number against s/n 162078 to confirm this is the right set for your engine – later engines used a different configuration.
