The piston end is probably threaded with a nut to hold the piston. I've found the best way to get one fixed is to take the cylinder off and take it to a good rural machine shop where they have big enough tools to take it apart without doing damage, and to put it together again. Its a standard part of the business at Randall Machine at Randall Iowa. On the other hand there's a place at Elkhart Iowa that will charge 5 times the new price for the cylinder to rebuild it. Their clientell seems to be cities with no knowledge of pricing. Elkhart charged me $25 a cylinder to take them apart and give me that outrageous quote. One place I've found cylinders at decent prices is at Northern, though the one I bought there for my Long backhoe proved to be false economy. It fit the place but had a few inches longer stroke. When pushed all the way the first time I needed to pick the tractor up out of a ditch, I bent the piston rod. My friendly shop straightened it easily with his 50 ton press (and he's not surprised by seeing bent hydraulic cylinders with bent rods), but the next time I did that I not only bent the rod but cracked the end casting. Then I bought the right cylinder from Long and its a better match. Sounds as if the previous owner did a good job of cleaning up the oil spray before he sold the rig. Likely the o-ring has worn out, there probably are some backing rings, and maybe a scraper type seal mostly used for cleaning the piston rod. Baum Iron does show a very wide variety of such parts at quite reasonable prices. Getting the cylinder and rod separated is most of the labor in fixing the leak. Worth the $20 or 25 I pay Stan Svenson at Randall. Gerald J.
