In this video, I show a Rieco Titan hydraulic camper jack that I disassembled (lower jack portion). The jack had began leaking; I replaced an Oring and hopefully solved the problem. This will show you a little more about the workings and simple repair procedures for this jack. (P.S. as of May 8, 2011 the repair is holding, jack's not leaking. An Oring did the trick!
