Total Newbie here, I had to rebuild both Hydro pumps on my Lazer Z HP this year as they both went up, bearings. I flushed the entire system, cleaned everything and replaced all bearings, seals, and a few other parts in both pumps. I pre-filled the pumps with Mobile 1 15w-50 before putting the tops on to hopefully prevent problems. I have tried everything i can to get it bled, I can not get the wheels to build up any kind of speed or pressure. I have the machine on blocks, If I crack the High Pressure line fitting on the reverse line I can get the wheel motor to start turning, it builds a little speed, but will not build pressure and is not going full speed. As soon as I close the fitting, the wheel stops, It does the same thing on both sides, and it will not run both motors at once. Does anyone have any idea what I need to do or check??? This thing is killing me. Thanks in advance for any help.
