Description

When you’re noticing your International Harvester losing compression, burning oil, or running rough, chances are it’s time for some valve work. A worn cylinder head with leaky valves can turn a dependable workhorse into a frustrating machine that struggles to pull its weight. This comprehensive service kit gives you everything you need to get that head breathing right again and restore your tractor’s full power.

What You’re Getting

Complete valve train components including intake and exhaust valves that seal properly under compression
Quality valve guides that keep everything aligned and prevent oil from seeping into the combustion chambers
Heavy-duty valve springs engineered to handle the demanding cycles of farm work
Professional-grade valve keys and retainers for secure assembly that stays put
All the small parts you need so you don’t have to hunt down individual components

Built for Real Farm Work

This service kit is designed for International Harvester tractors that put in long days pulling implements, running PTOs, and handling heavy loads. Whether you’re running a utility tractor for loader work or a row-crop machine for field operations, proper valve sealing is what keeps your engine developing full power when you need it most.

Made to Last

These aren’t bargain basement parts—they’re built to handle the heat, pressure, and constant cycling that farm engines endure. The valves are manufactured to original specifications with materials that resist warping and wear, while the springs maintain proper tension season after season.

Installation Notes

This is a job for someone with machine shop experience or a good relationship with their local engine rebuilder. Valve work requires precision measuring, proper machining, and the right tools to get everything seated correctly. Take your time and do it right—a properly rebuilt head will give you years of reliable service.
