Description
When your International Harvester tractor starts losing power or running rough, worn exhaust valves might be the culprit. These valves take a beating from the extreme heat and pressure of combustion gases, and over time they can warp, burn, or develop pits that hurt engine performance. A fresh set of exhaust valves gets your engine breathing properly again and running like it should.
What You’re Getting
- Quality TISCO construction built to handle the heat and stress of diesel combustion
- Precise machining ensures proper fit and sealing in your cylinder head
- Each engine requires 4 exhaust valves for complete replacement
- Direct replacement part that installs just like the original equipment
Built for Real Farm Work
These exhaust valves fit the reliable 4-cylinder engines found in International Harvester 100 Series, 200 Series, and Super A and C Series tractors. Whether you’re pulling a plow, running a cultivator, or powering a hay baler, these are the workhorses that kept American farms running for decades. The 123 cubic inch engine in these tractors was built to last, and proper valve maintenance keeps them going strong.
Made to Last
Farm tractors don’t get babied, and these exhaust valves are engineered to handle whatever you throw at them. The valve face and stem are manufactured to precise tolerances using materials that resist the high temperatures and corrosive exhaust gases that would destroy lesser parts. Quality construction means fewer breakdowns during busy seasons.
Installation Notes
Valve replacement is part of a complete top-end rebuild, so plan on new valve springs, guides, and seals while you’re in there. A valve grinding might be needed depending on the condition of your cylinder head. This is a job for someone comfortable with engine work, but the reward is an engine that runs like new again.
