Description
When you’re doing valve work on your International Harvester engine, these little valve keys might seem insignificant, but they’re what keep your intake and exhaust valves properly seated in the cylinder head. Without them doing their job, you’ll have compression leaks, poor engine performance, and eventually valve damage that’ll cost you a lot more than a few small parts.
What You’re Getting
- Precision-machined keys that lock valves securely in position
- Quality steel construction that won’t crack or break under spring pressure
- Exact fit for International Harvester engines—no grinding or modification needed
- Multiple keys per engine required, so having spares saves you downtime
Built for Real Farm Work
These valve keys are designed for the workhorse International Harvester engines found in countless tractors across farm country. Whether you’re rebuilding a vintage Super C or maintaining a 400 series tractor, proper valve keys are essential for keeping compression where it should be and your engine running strong through long days in the field.
Made to Last
Engine valve keys take tremendous stress from valve springs that can exert hundreds of pounds of force. These keys are manufactured from quality steel that’s heat-treated to handle that constant pressure without deforming or breaking. They’re built to last as long as your engine rebuild.
Good to Know
Valve keys work in pairs—two keys per valve—and each engine uses multiple sets for all the intake and exhaust valves. When doing valve work, it’s smart to replace all the keys at once since they’re inexpensive insurance against future problems. A valve spring compressor makes installation much easier and safer.
