How to increase the AHOP oil pressure in F9E


Thread Starter


We have 5nos of F9E machines with Mark VI controls, we normal shutdown the unit for bleed valve replacement activity. then during start up we found that AHOP discharge pressure only 50Bar, and we try to increase the compensator but the result same. we replaced the new AHOP but the result same. O/P pressure only 50Bar. please kindly advise to me how to increase the pressure or how to identify the any leakage in the system
