[QUOTE="jmatt20, post: 8406, member: 186"] yes it is possible ,the seal works one way and dosen't seat right in the other dirrection ..same seal for each direction . if you can remove and reseal your controll valve you should have no problem realsealing a cylinder. pul the cylinder out of the machine ,put it in a vice ,remove the head and pull the rod out. a big nut holds the piston on the end ,remove it and slide the head off and your ready to remove and replace the seals. the book shows a couple of special tools to install the seals but the job can be done without them. the fiber seal on the piston is the one to be most carefull with, soak it in oil for a while and then flex it in your hand for a while to take a little of the stiffness out of it ,then start one side of it in the groove and slowly work it around the piston. when it goes on it will seem lose ,like youv'e streched it out but the end of the tube is tapered and it compresses into the groove when reassembled. the rod seal is a bear also but it is rubber so as long as you don't cut it you can manhandle it all you want ,just make sure that when you're done it's seated like the one you took out. if you have time you can source the seals from a hydraulic shop for less than bobcat. you can also get the kit from bobcat and then take the old seals to the hydraulic shop and make up some kits for the next time you have to reseal.
