Message: <blockquote data-quote="TriHonu" data-source="post: 15494" data-attributes="member: 897">When both cylinders are pinned at the back end, with all the hoses hooked up *properly*, but both working ends of the cylinders are not yet pinned to the top of the boom, should the rods obey the inputs just as if they were pinned? - YesIf you only disconnected the hoses at the two boom cylinders you should only have 4 hoses disconnected, two on each side.  Is this correct?When you start the loader is there any hydraulic fluid coming out of any of these hoses?  There shouldn't be any fluid under pressure coming out of the lines.  If you do, you probably have a control valve leaking or stuck.Get a helper.  Have them stand to one side and watch the hoses on that side.  You start the loader and operate the boom lift control just enough for fluid to come out of the hose.  That hose should be connected to the cylinder port that supplies the base of the cylinder.  The other line on that side connects to the port that supplies the rod end of the cylinder.  Do the same thing on the other side.There are three ways to hook up the cylinders:1. If you connect one side correct and one side incorrect when you try to raise the boom one side will be trying to push the boom up and the other side will be trying to pull the boom down.2.  If you hook up both sides incorrect and try to raise the boom it will pull down and when you try to lower the boom it will raise up.3.  Both sides hooked up correct it will work properly.</blockquote>
