Description
When your six-cylinder diesel is smoking, losing compression, or just doesn’t have the pull it once did, worn pistons and rings are usually 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. This complete kit gives you everything needed to restore proper compression and power in your 6-590 diesel engine—pistons, rings, pins, and retainers all engineered to work together.

- 0.5mm oversized pistons designed for engines that have been previously bored
- Complete ring sets with proper tension for lasting compression and oil control
- Precision-fit wrist pins and retainers for smooth, reliable operation
- All components manufactured to meet or exceed original specifications
- Single kit rebuilds the entire 6-cylinder power plant
Built for Real Farm Work
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. The 6-590 engine was built to handle heavy-duty applications, and this rebuild kit restores that dependable performance you need for field work, harvesting, and daily farm operations.
Made to Last
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. The oversized pistons are precision-machined to restore proper bore clearances after machining, ensuring optimal performance and longevity.
Good to Know
This is an oversized kit, so your block will need to be bored 0.5mm over standard before installation. Make sure to have your cylinders professionally honed to the correct finish for proper ring seating. This is a complete teardown job that’s perfect for winter shop time when the tractor’s not needed daily. You’ll want to have the block and head professionally cleaned and checked for cracks before assembly. Take your time with ring installation—proper gap settings are critical for long engine life.
