I've had a leak down issue with my FEL since I added a few a grapple a few months ago. There were/are no leaks, but with the tractor running, the FEL lift and curl leak down slowly. I've posted about this before and someone suggested replacing the poppets in the control valve which I did. The problem stopped and I thought it was fixed, but it came back.
Reading another post, someone mentioned that a common mistake is not cleaning debris out of new hydro hoses before installing them. I'm guilty of that and I'm beginning to believe that's the problem. One big reason for this is that the problem seems to get worse the longer the tractor runs which I think indicates it gets worse once the trash gets stirred up.
The only other thing I think it might be is something new I read here last night. Someone said something about air being smaller than hydro fluid and just because there's no hydro leak doesn't mean there's no air leak. I'm probably going redo all the fittings I added just make sure.
My question is how do I make sure I get all the trash out of the hydro system? I did my 50 hour service shortly after installing the grapple and I did replace the hydro fluid and filter and the HST filter. I didn't go to any trouble to make sure all the oil was out of the cylinders and hoses.
