I'm attempting to build a log splitter. I finally got it all assembled and it works great but seems very slow. I have a briggs 5 hp motor, Haldex 11 gpm pump, cross 2500 psi converta valve and a lion 4x24 cylinder. I think the problem is the pump. although it is a 2 stage it starts on the first stage and gets about 2 inches (very fast) and then slows down to second stage (very slow) even under no load pushing and pulling. I placed my filter on the suction side of the pump which I know can be a problem, but I went to tractor supply when I started building this and they all seem to have them on the suction side. Any idea for what wrong?
