Description
When your diesel tractor is losing power, burning oil, or just not pulling like it used to, worn piston rings are often the culprit. Maybe you’ve noticed blue smoke on startup or your engine’s using more oil than usual—classic signs that it’s time for a rebuild. This piston and ring kit gets your engine back to sealing properly, restoring that crisp compression and smooth operation you need for long days in the field.
What You’re Getting
- Complete 4.4-inch standard bore pistons and rings for a proper rebuild
- 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
- Standard bore components that fit properly without machine work
- Quality parts built to handle thousands of operating hours
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 4.4-inch bore size fits a variety of diesel engines across different tractor brands and models.
Made to Last
The liner materials are designed to handle the thermal cycling and high pressures of diesel operation without wearing out prematurely. Quality construction means you won’t be tearing the engine down again in a year or two. These components are built to the same standards as the originals that came in your tractor from the factory.
Installation Notes
Ring installation requires engine disassembly and proper measuring tools to ensure correct fit. Check your cylinder bore for wear or scoring before installing new rings – sometimes cylinders need honing for proper ring seating. This is typically a winter shop project when you can take your time and do the job right.
