Ck81 has problem with LS pressure. Main pressure and Ls pressure difference should be ~15-18bar. Now it is 60bar. What I check next? Checked: -filters. (Include ls line hose filters 2pcs) -Oil return valve block. (P10) -Hydraulic pump valve block. -no leaks at Ls hose line.
Good day The LS pressure needs adjusting if it has been measured in the correct way it seems a long way out. Kind regards Uffex
Yes but where to adjust. Standby pressure 30bar (can adjust) then Ls pressure is 0bar. When using boom pressure 200bar and Ls pressure 160bar. Manual doesnt tell where to adjust Ls pressure only tell to check p10 block and its Ok. Pressures are measured correct way.

Good day Nozzz We have looked at the problem unfourtunaly the only helpful pump illustrations is that of the current Linde pump we have made our comments on the attachment hope it helps you. Kind regards Uffex
