Yes, rotate the female spline socket one way to tilt then back the other way to close putting a bar in the pump piece on the right and pumping.
You might find the bar and spline tool under the front bonnet cover if you lift it.
Keep your fingers crossed that when you pump and put the system under pressure that the metal pipes under the cab aren’t corroded and give way.
Also don’t work under it without the cab fully tilted forward it will fall the last bit forward under it’s own steam you should notice meaning it’s safe. Also keep your finger’s crossed it doesn’t pull the ram apart and the whole cab faceplants the yard.
Just use something like a bit of flat bar in some mole grips to twist the spline socket and then any old bar that fits to pump.
