I am trying to resolve the pressure issue.
I have replace the 12 vanes in the Vickers Vane Pump.
Replace hydraulic oil, remove and clean the suction and pressure tube.
Start the engine and look at the movement in the hydraulic reservoir, lots of Bulbe but no oil coming out of the pressure tube that feeds the lift cover, normally oil should come out a few inches high.
Any idea of what is the problem.
Thank you for your help.
