Piston Ring Set for John Deere 20, 30, 35, and 40 Series Diesel Tractors

Description

When your John Deere diesel is burning oil, blowing blue smoke, or just not pulling like it used to, worn piston rings are often the culprit. When your diesel tractor is losing compression, burning oil, or just not running with the power it used to, worn piston rings are often the culprit. This single cylinder piston ring set gets your engine back to sealing properly, restoring that crisp compression and clean operation you need for a full day’s work.

What You’re Getting

• Complete ring set for one cylinder – compression rings and oil control rings included
• Precision-machined rings that restore proper cylinder sealing
• TISCO builds their piston rings to handle the harsh conditions inside diesel engines – high compression ratios, constant heat cycling, and the contaminants that come with farm work. These rings are manufactured to maintain proper tension and sealing through thousands of operating hours.
• Direct replacement – no machine work required on standard bore engines

Built for Real Farm Work

These John Deere 20 and 30 series tractors were the backbone of American farming, and the 40 and 50 series continued that tradition of reliable power for everything from cultivating corn to baling hay. Whether you’re running a 2020 on smaller jobs, working fields with a 4020, or pushing a big 4850 through harvest season, keeping an eye on engine temperature is critical when you’re working these machines hard. This ring set is designed for diesel tractor engines that power the equipment you depend on every day. Whether you’re running tillage tools, hay equipment, or loader attachments, proper compression is what gives your tractor the pulling power to handle tough jobs without strain.

Made to Last

These rings are built to handle the punishment that comes with diesel farm engines – high compression ratios, constant temperature cycling, and the dust and debris that’s part of field work. The materials and manufacturing process ensure proper ring tension and cylinder wall contact for reliable sealing that lasts.

Good to Know

This is a single-cylinder set, so order the quantity you need for your engine rebuild. Most engines will need some honing or boring work unless you’re catching the wear early. If you’re doing a full rebuild, now’s the time to check your pistons, cylinders, and bearings while everything’s apart.
