Looking for a little advice here group...I am trying to find some parts to repair the leaking single acting cylinders on my Freeman manure loader for my JD 420. I tore into one of the cylinders to get an idea of what I may need. Everything looks pretty good, but I clearly need to replace what the parts diagram calls "v leather packings" I did find a few similar products online, but none of the have the same dimensions that I am looking for. I am considering using what is called a Type B rod seal or Type B PolyPak. Anyone have any experience with this? My biggest concern is that I cannot find the exact OD that I need. My cylinder rod has a 2 1/4" ID, which is no problem, but the packing gland where the seals go is about 3.050" and I'm afraid that 3" would be too small and 3 1/8" too big. Any thoughts?
