Description
If you’ve noticed your tractor losing power, running rough, or burning oil, worn exhaust valve seats could be the culprit. These precision-machined seats create the critical seal between exhaust valves and cylinder heads, controlling the flow of hot exhaust gases out of your engine. When they’re worn or damaged, you’ll lose compression and power right when you need it most.
What You’re Getting
- Precision-machined sealing surface that creates proper valve-to-seat contact for reliable compression
- Heat-resistant materials built to handle extreme diesel exhaust temperatures and pressures
- Direct replacement part that restores factory performance and fuel efficiency
- Quality construction that handles the constant heat cycling from cold starts to full operating temperature
Built for Real Farm Work
These valve seats serve the reliable diesel engines powering your modern workhorses. Whether you’re running a T5.120 on daily chores, pulling heavy tillage with a T6.175, harvesting with a T7.245, or handling livestock operations with a Case Maxxum 140, these engines deliver dependable power through long seasons – but only when the valve train seals properly.
Made to Last
Farm tractors work hard under varying loads and temperatures, and valve seats take constant abuse from combustion pressures and corrosive exhaust gases. This replacement is built to handle those demanding conditions while maintaining the precise tolerances needed for proper valve sealing season after season.
Good to Know
Valve seat replacement is major engine work that requires proper tools and machining knowledge. The cylinder head usually needs to be removed and sent to a machine shop for seat installation. While you’re doing this work, it’s smart to check valve condition and consider a complete valve job if the engine has high hours.
