Turning up the hydraulics

[tarbaby]

the pressure relief valve is shimed at the end of the spring, the addition of another shim at the same thickness of the shim that is used will adjust the pressure up that amount of the thickness { 0.0050in shim should bring the pressure up increased 50psi } from the wsm manual, you need a pressure gauge, hook up and check the pressure now then shim and recheck pressure,Caution is used with any hydraulic unit.
