Replacing the hydraulic valve body on a kubota front loader. This set up is wrong! This is the way it was set up and the way I put it back together but a viewer has pointed out to me it was and the reason it failed.
In this video the output is feed into the input of the next valve body but that does not offer a escape for the building pressure after the pressure release valve is opened. The power beyond port must be used to feed the input of the next valve an the out put port MUST directly feed to the oil reserve tank to adequately regulate high pressure spikes after the pressure release is opened.
