Description

When your engine starts running rough, making noise, or losing power, worn exhaust valves are often the culprit. These valves take a beating from the constant heat and pressure of exhaust gases, and when they’re not sealing properly, you’ll feel it in performance and hear it in the way your engine runs. This TISCO replacement exhaust valve gets your International Harvester tractor back to running smooth and strong.

What You’re Getting

Precision-engineered valve that meets original equipment specifications for proper fit and function
Heat-treated construction designed to handle the extreme temperatures of exhaust gas flow
Proper valve face angle and stem dimensions for tight sealing and smooth operation
Quality materials that resist warping and wear for long-lasting performance

Built for Real Farm Work

This exhaust valve fits 4-cylinder gas engines found in International Harvester’s utility and row-crop tractors from the classic era. These workhorses were built for everything from cultivating corn and beans to running hay equipment and handling loader work around the farmstead. With four valves needed per engine, having reliable replacements on hand keeps your tractor running when the work can’t wait.

Made to Last

TISCO builds these valves to handle the demanding conditions inside your engine. The valve face is precisely machined to seal against the seat, while the stem is sized for proper clearance in the guide. Quality materials resist the corrosion and heat damage that can sideline your engine during busy seasons.

Good to Know

Valve replacement requires some mechanical know-how and the right tools to compress valve springs safely. It’s a good time to check valve guides, springs, and seats while you’ve got things apart. Always replace valves in sets to maintain even compression and performance across all cylinders.
