I fail to see where he says anything about loader function, good or bad. I always want to start with the basic things first. My day is full of guys that want to buy hydraulic pumps before filters and injection pumps before fuel filters and lift pumps. It is nuts. There is a logical path to troubleshooting, or should be.If thats true then there wouldnt be any point in checking the filter/suction and possibly the relief.
Tested the pressure at the boom and getting 2150 with the michine idling. So now Im at a loss lol
