This is easy to install (it just screws in like a plug ) and it also makes a great hydraulic trouble shooting tool. Try this before you replace the pump. A new pump will only put out the pressure that the relief valve will allow. These valves sell for well over $250.00 from CNH. Email if you need help diagnosing your hydraulic problems.
