Description
When your old International Harvester tractor starts running rough or losing power, worn intake valves are often the culprit. These valves control the air-fuel mixture entering each cylinder, and when they’re not sealing properly, your engine can’t breathe right. This TISCO replacement intake valve gets your engine back to running smooth and strong, just like it did when it rolled off the factory floor.
What You’re Getting
- Precision-machined valve that meets original IH specifications for proper fit and function
- High-quality steel construction that handles the heat and pressure inside your engine
- Proper valve face angle ensures a tight seal against the valve seat
- 4-57/64 inch length matches factory dimensions exactly
Built for Real Farm Work
This intake valve fits International Harvester 100 series, 200 Series, Super A-1 Series (prior to S/N 310300), Super AV-1 Series (prior to S/N 310300), and Super C Series tractors. These are the workhorses you’ll find cultivating fields, running hay equipment, and handling all kinds of farm chores. The 4-cylinder gas engines in these tractors were built to last, and with proper maintenance they’ll keep running for decades.
Made to Last
Farm engines work hard in dusty, dirty conditions, and intake valves take a beating from constant opening and closing thousands of times per hour. This valve is built from quality steel that resists wear and maintains its sealing surface even after years of operation. TISCO makes these valves to handle the demands of real farm work.
Good to Know
Each 4-cylinder engine uses four intake valves—one per cylinder—so you’ll want to replace them as a complete set for best results. While you’ve got the head off for valve work, it’s a good time to check your valve guides and springs too. A little valve grinding compound helps ensure a perfect seal when installing new valves.
