Description
If your IH tractor is smoking blue or burning oil like it’s going out of style, worn piston rings are likely the culprit. Crankcase blowby, oil consumption, and that telltale blue smoke on startup are all signs that it’s time to get your engine sealed up properly again. This three-ring set gets one cylinder back to compression specs and stops that oil from sneaking past where it shouldn’t be.
What You’re Getting
- Complete set of three rings per cylinder: one compression ring at 1/8″, one at 3/32″, and one oil ring at 3/16″
- 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
- Precision-manufactured for 3-7/8″ standard bore – no modifications needed
- Direct replacement rings that restore proper cylinder sealing and compression
Built for Farm Work
This ring set fits the classic International Harvester and Farmall tractors that have been the backbone of American farms for decades. Whether you’re running an older Farmall or a utility tractor, these engines were built to work hard day after day. When the rings start wearing out, you lose power, burn oil, and create the kind of smoke clouds that make neighbors wonder what you’re up to.
Made to Last
Farm tractors don’t get babied – they work in dust, dirt, temperature extremes, and get pushed to their limits during busy seasons. These rings are built to handle that kind of abuse while maintaining the seal that keeps your engine running efficiently and cleanly.
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 definitely a winter shop project or something for your mechanic – not a quick field repair.
