Loader leaking down.

[bigbull338]

loaders with bad seals dont always bleed off slowly.an i sure wont walk under any loader thats raised.

In the scenario of unplugging hoses to see if the loader settles, the loader could leak down if the seals on the piston(s) are bad, and leak no oil out. The oil simply leaks from one side of the piston to the other. (Air will make up for the difference in volume) I wouldn't do this test. Unplugging hoses under load is not a good idea and you will have to take the load off or somehow bleed the pressure off to get the hoses plugged back in. There are some quick couples that can be coupled under pressure, but not likely found on a tractor loader.

You could take the piston completely off the shaft, stuff the shaft back into the oil filled cylinder and it still wont leak down (as long as the shaft seal isn't leaking). This is Correct

There is less volume on the side of the cylinder with the rod. Even it the seals on the piston are completely remove as Willl suggested, it still wouldn't leak down, because in order to do so, you are shoving more rod into the cylinder body. That will have to displace fluid somewhere. If the hoses dont leak, and the rod seals dont leak, the fluid has nowhere to go, so it wont leak down.

Right you are.
