Description

When your International Harvester starts burning oil, running rough, or you hear that telltale clicking from the valve train, worn valve guides are often the culprit. These little cylindrical bushings guide your valves as they open and close thousands of times per minute – and when they wear out, your valves can’t seal properly. This replacement valve guide gets your engine back to running smooth and clean.

What You’re Getting

Precise bore dimensions that guide valves straight for proper sealing
Durable cast iron construction that handles the heat and constant motion of engine operation
Machined to exact OEM specifications for perfect fit and function
Quality TISCO manufacture that meets or exceeds original equipment standards

Built for Real Farm Work

This valve guide fits International Harvester tractors from the classic C-Series and A-Series models that built the reputation for reliability IH was known for. These guides work in the 100 series, 200 Series, Super A-1 Series, Super AV-1 Series, and Super C Series tractors – machines that were the workhorses of American farms for decades and are still earning their keep today.

Made to Last

Engine valve guides take a serious beating from constant heat cycling and the repetitive motion of valves opening and closing. This replacement is manufactured from quality materials designed to handle the demanding conditions inside your engine. The precise machining ensures proper clearances that reduce wear while maintaining the tight tolerances needed for good valve sealing.

Installation Notes

Valve guide replacement requires specialized tools and experience – this is typically a machine shop job rather than a field repair. The old guides need to be pressed out and new ones pressed in, often requiring reaming to final size. If you’re rebuilding the whole top end, consider a complete engine overhaul kit that includes valve guides along with springs, valves, and gaskets for a comprehensive refresh.
