Description
When your engine starts running rough or you’re losing compression, a worn exhaust valve seat could be the culprit. This precision-machined valve seat ensures your John Deere’s exhaust valves seal tight against the cylinder head, keeping your engine running at peak performance and preventing costly compression loss.
What You’re Getting
- OEM-quality valve seat designed specifically for John Deere 4239T, 4239D, 6359T, and 6359D engines
- Precision-machined sealing surface that creates proper valve-to-seat contact for maximum compression
- Heat-treated construction that withstands extreme engine temperatures and combustion pressures
- Exact replacement that installs without modification or special tooling
Built for Real Farm Work
This exhaust valve seat fits a wide range of John Deere tractors from the reliable 2130 utility tractor all the way up to the powerful 4050 row-crop machine. These tractors handle everything from loader work and hay operations to heavy tillage and planting, so the engine components need to be built to last through long hours and demanding conditions.
Made to Last
Farm engines work hard, and exhaust valve seats take a real beating from hot combustion gases and constant valve impact. This seat is manufactured to OEM specifications with heat-resistant materials that maintain their sealing properties even under extreme operating conditions. The precise machining ensures proper valve contact for years of reliable service.
Installation Notes
This valve seat requires professional installation with specialized tools to press it into the cylinder head. Most machine shops can handle the installation, and it’s often done as part of a complete valve job. If you’re rebuilding the top end of your engine, now’s the time to replace these seats along with the valves and guides.
