In this video I am disassembling a hydraulic car jack that I bought for 15 euro. I wanted to see how it works and in which quality the parts are. I didn`t disassemble all of the parts. The pipe in the middle, the safety valve , and the ball valves are still in place, because I have no reason to do it. Everything is visible in the photos and the function also became clear. I have plans for an alternative use of the hydraulic jack, I will post about it once I have tested it.
