Description
When your old International Harvester starts getting hard to start or loses power under load, worn intake valves are often the culprit. These valves control the fuel-air mixture flowing into each cylinder, and when they don’t seal properly, you’ll notice rough idling, poor performance, and higher fuel consumption. Getting the right replacement valve gets your tractor breathing properly again.
What You’re Getting
- Precision-made intake valve designed to original specifications for proper sealing
- Quality steel construction that handles the heat and stress of engine operation
- Correct valve stem diameter and length for proper timing and clearances
- Direct replacement that works with your existing valve guides and springs
Built for Real Farm Work
This intake valve fits International Harvester 100 series, 200 series, Super A-1 series (prior to serial number 310300), Super AV-1 series (prior to serial number 310300), and Super C series tractors. These are the utility and row-crop tractors that handled everything from cultivating corn and beans to running hay equipment and loader work around the farmstead.
Made to Last
Farm engines work hard, especially during planting and harvest seasons when you’re running long hours. This valve is built from quality steel that resists warping and wear, maintaining proper compression and valve timing even after thousands of hours of operation.
Installation Notes
This valve has the correct 4-57/64 inch length and will work with your existing valve guides and springs. Since you need four intake valves per engine, it’s smart to replace all of them at once if you’re doing a valve job to ensure even performance across all cylinders.
