Description

When your Farmall starts running rough or you notice blue smoke coming from the exhaust, worn exhaust valves might be the culprit. These valves take a beating from hot combustion gases cycle after cycle, and when they start to leak, your engine loses compression and power. You’ll feel it in the field when your tractor struggles to pull implements that used to be no problem.

What You’re Getting

Precision-manufactured valves designed to handle the heat and pressure of constant farm work
Quality steel construction that resists warping and burning under extreme temperatures
Proper seating surfaces that create tight compression when paired with good valve seats
Direct replacement specification – no modifications needed for installation

Built for Real Farm Work

This exhaust valve fits International Harvester’s reliable 4-cylinder gas engines found in many classic Farmall tractors. Whether you’re running a Super A for cultivating, a Super C for hay work, or one of the 100 or 200 series tractors for general farm duties, these engines were built to last with proper maintenance and quality parts.

Made to Last

Farm engines work hard in dusty conditions with varying loads, from light cultivation to heavy tillage. TISCO builds these valves from quality steel that can handle the constant heat cycling and corrosive exhaust gases without premature failure. The valve stem is machined to proper tolerances for smooth operation in your valve guides.

Good to Know

Remember that exhaust valves work in sets – when one goes bad, it’s smart to replace all four while you’ve got the head off. Check your valve guides and seats while you’re at it, as worn guides will cause new valves to fail prematurely. A valve job is the perfect time to freshen up the whole top end and get your engine running like it should.
