When you’re rebuilding that trusty C123 gas engine in your IH tractor, you need every gasket and seal to be right the first time. There’s nothing worse than getting everything buttoned up only to find a leak that means tearing it all apart again. This complete gasket set gives you everything you need for a proper rebuild—head gasket, intake and exhaust manifold gaskets, oil pan gasket, valve cover gasket, and all the crankshaft seals and sleeves your engine requires.
What You’re Getting
- Complete gasket set covers every sealing surface in your C123 engine
- Includes crankshaft seals and sleeves to prevent oil leaks at rotating parts
- Quality construction that handles the heat and pressure of a hardworking gas engine
- Everything comes in one kit so you don’t have to hunt down individual gaskets
- Made by TISCO, a trusted name in aftermarket tractor parts
Built for Real Farm Work
This gasket set is designed for the C123 4-cylinder gas engine that powered plenty of International Harvester utility tractors back in the day. These engines went into tractors like the 130, 140, and 230, plus some balers including the 56T, 56W, 57T, and 57W models. Whether your tractor’s been running cultivators, mowing, or doing loader work, these are the same sealing surfaces that keep compression in and oil where it belongs.
Made to Last
Farm engines work hard and get hot, so these gaskets are built to handle the punishment. The materials are chosen to resist the acids and moisture that can form in a gas engine, plus they maintain their seal even when things heat up during a long day in the field. Quality construction means you can trust this rebuild to keep running season after season.
Good to Know
This is a complete rebuild gasket set, so make sure you’re ready to do the whole job—it’s not economical to use just part of the kit. Clean all sealing surfaces thoroughly with a scraper and solvent before installing new gaskets. A little gasket sealer on metal-to-metal joints helps ensure a good seal, but don’t overdo it or you’ll have squeeze-out to clean up later.
