I replaced a hydraulic line on the front end-loader on a Ford 1710 tractor ater it broke. AFterwards, I checked the hydraulic fluid in the resivour and it was still over full by about 1 to 1.5 inches so I didn't add any new fluid. When I start the tractor and run the front end loader up and down it works fine for about 2 to 4 minutes but then starts surging about 2 times a second. From what I've found online (very little) I may have air in the lines. I've been told that this system is self-bleeding and I should only have to move the bucket up and down and it should bleed itself. My problem is that it still surges and the bucket slows until it won't even move. Any ides? Can I add more fluid which is already about 2 inches above full but about 1 to 1.5 inches from the top of the case? Thanks, JR
