My JD450 has developed a crack in the 1' diameter metal hydraulic line that runs from the pump in front all the way back to the main control valve. The crack is right up front where the 1' tube was bent rather sharply 90 degrees, too sharply I believe as the tube is about halfway crimped there creating an oval cross-section which, of course, flexes as the ~2000 psi comes and goes in that line.

Coll O Crimp T400

Well, I've got a TIG welder and I'm pretty good at repairing such things so I tried to remove that line today. Whew! After a hell of a struggle with monster wrenches that ended up involving a come-along to pull on one of the wrenches!, I got it loose at both ends but there's just no way that line can be removed from the crawler without taking a lot of other stuff apart. I even removed the 1.5' diameter return line that runs right along with the 1' supply line and still there isn't enuf room to get that thing out. The problem is that the rear end of the line is also bent up 90 degrees and the bent leg is about 5-6' long and there's just no room for that leg to snake out through the frame.
Plus, in view of the failure mode, I don't think a weld would hold for very long. That oval section of the pipe is never going to stop flexing.
So I'm asking the experts here if replacing that metal line with a hose is a workable idea? I'm hoping I could get some factory-made 90 degree elbow fittings for the hose ends that would keep me from having to bend the hose itself real sharply.
Thanks in advance.
