Oil & Fuel Priming the hydaulic system???!!!!

[JohnDeere391]

A steel small main line on our 4500 broke and i am going to replace it. Do i just put the line on and move the loader and backhoe control to prime the system or do i have to bleed the air out?

Just put it on and cycle all the hydraulics through their full range of motion about 6 or 8 times, it will be bled. First couple times ya cycle it, it may be a bit jerky, that clears up after a time or two once the air gets out of the lines.
