Built for Real Farm Work
This valve works with the proven 4045T and 6068T Powertech engines that power a huge range of John Deere tractors from compact utility models through heavy-duty workhorses. Whether you’re running a smaller tractor for livestock work or operating a larger machine for row crop farming, these engines see serious use in demanding conditions where reliability matters most.

Installation Notes
Valve replacement is a job best left to experienced mechanics, as it requires cylinder head work and precise valve train assembly. Make sure to check valve guides and seats while you’re in there – this is also a good time to inspect other valvetrain components for wear. Proper torque specifications and valve lash adjustments are critical for reliable operation.
