I figured I would just start a thread on this project as it’s going to be on going.
I am going through our new to us 5519 and noticed a couple things. 1 when in neutral it wants to move backwards, 2 when you start it it seems like one side of the hydraulic system has pressure when the controls are in neutral. For example I took the boom extension cylinder out and had to start it. Fluid was pumping out one of the lines which I though was weird. Had to rebuild the slave cylinder and it extended when I started it with one end not pinned. I am guessing they are connected some how, like something is bypassing/ back feeding.
The machine has several issues and trying to work through them one by one. One is the park brake solenoid is burned up, brakes were bypassed and the brake fluid drains out of the tank. So I think the seals are gone in the brakes but haven’t got that far yet, need to drain the oil and see if it’s been thinned out. Just trying to get the major leaks fixed and a service done.
Since threads are better with pictures…
Here it is with the cylinders out for rebuild, the seals were shot and puking out oil.
