How to prime hydralic pump?

For the guy that has split his tractor, hardly worth taking the pump apart just to add the jelly. Most times when you split the tractor a combination of oil left in pump, oil still in lines, clean screen in touch control and a full reservoir, the pump will self prime very quickly. The full reservoir makes a huge difference, you only have to jack the left rear wheel about 4" and oil will run to pump via graviety, if the air can get out. Fill the system with oil, jack the rear wheel and go to dinner, oil will bypass the air while you dine.

Another item that could be impedeing oil flow is the screen in the touch control unit. Oil flowing to pump must go through that screen, thus the screen must be clean. I always clean that screen if I have a tractor split. It should be done yearly anyhow. Very likely when you had those lines off, you lost all oil in them, now oil must flow to pump by graviety, and anything you can do to enhance that graviety will help.
