Hello, I have a bobcat 753 and the lift arm cylinder hose is leaking where it connects to the cylinder. It is the cylinder on the left side of the machine when you are sitting in it. It is the inner hose which I believe is the lift hose and not the return. It does not connect to the metal tube. I am wondering how to remove this hose from the cylinder. There is a place for an allen wrench in the square block where the hose connects. Is this the removal point or should I disconnect the outer hose and try to unthread the inner hose? Thank you for your time. This is a great forum and you guys have been very helpful in the past.
