    140 hydraulic site tube

    Site tube was so discolored I couldn't tell if there was any fluid in it. I tried to wipe it, and it snapped like a cracker. The entire tube just fell off. Got new tube, but I didn't replace the little filter looking thing in the line. And, no fluid shows in the tube even though it won't accept any more fluid. Just what is that little filter looking thing and what is it's function?

    Sgt, The filter is simply a vent. Your hydro is a sealed unit and the filter "vents" the site tube allowing oil to flow into the site tube. Remove filter and examine closely. You should find a small (1/16" ??) hole on one end of the outside. Make sure this hole is open and reinstall filter with hole facing upward. Bob

    thanks a ton, RW. I saw the little hole when I was putting it back together. When nothing would come into the tube, and I couldn't get any fluid into the reservoir, I started to wonder about that little hole.
