The hydraulics have stopped working all of a sudden.On repeated attempts the hydraulics work for a minute or two after intervals.We adjusted pilot pressure heand the hydraulics worked for slightly longer.We have replaced the pilot gear pump but the problem persists.Kindly advise.

The magnet on your safety solenoid has likely failed. Please replace with magnet of high speed travel. This will verify the problem and get you running til parts are available.
If memory serves, it should be the magnet closest to counterweight as you open the pump room door

Just checked. The solenoids arent near the pump room door. They're behind the cabin before control valve ( MCV) and the one closest to door is the safety solenoids.Not sure which of the 3 is to be interchanged??

Doesn't matter which serial break, it's always in the pump room on the floor

Look at the orientation, in the valve. Identify and mark the wiring, measure voltage, to confirm.
High speed travel is almost always at opposite end of valve bank. Good luck, be safe. By the way, there is a manual plunger you can depress with a pick if someone else can pull a function for you to absolutely confirm.
You just need the magnet, no need to open hydraulic system or make adjustments
