Description
When your tractor starts burning oil, losing power, or blowing blue smoke out the exhaust, it’s usually telling you the piston rings have had enough. After thousands of hours in the field—plowing, planting, and pushing heavy implements—those rings wear down and can’t seal the cylinders like they should. This complete piston ring set gets your Small Dual Power engine back to running strong and clean.
What You’re Getting
- Complete set includes compression rings and oil control rings for full cylinder restoration
- Cast iron construction handles the heat and pressure of diesel combustion without breaking down
- Pre-gapped design means proper end clearance is already set for thermal expansion
- Heat-treated materials keep their shape under the high pressures of agricultural work
- Surface treatments reduce friction and help the rings last longer between overhauls
Built for Real Farm Work
This ring set fits the Small Dual Power engines found in Ford New Holland 40, TS, TM, and TL series tractors. These are the workhorses you see doing heavy tillage, running big balers, and pulling grain carts during harvest. The Small Dual Power configuration gives you that extra boost when you need it most, and these rings help maintain the compression that makes it all work.
Made to Last
Farm engines work hard—long hours, heavy loads, and dusty conditions that test every component. These rings are built from materials that handle the punishment, with treatments that reduce wear and help them maintain their seal season after season. They’re designed to restore your engine’s compression to factory specs so you get the power and fuel efficiency you’re paying for.
Installation Notes
This is a major engine job that requires pulling the pistons and completely disassembling the top end. Most folks take this opportunity to check cylinder bore condition and hone if needed. While you’re in there, it’s smart to replace gaskets and seals too—saves doing the job twice when something else starts leaking.
