How a hydraulic jack works

How a hydraulic jack works
The hydraulic jack is a very useful device for lifting even heavy cars or other loads with the least effort. It is an amplified version of the lever. Here I explain with animations how it works inside.

You don't have to use the temp gun just did it so YOU can see how much heat is put into the hub. Tried this a couple of times, I really like it vs cutting and hammering on the wheel bearing

    The demo is good, but the reason why so many people disliked it is the voice in the beginning is shocking. Other than that, the demo is great.

    This explanation is half a bubble off. The only lever effect is to push the small piston down by leveraging against the mechanical link above C. The lever provides a "mechanical" advantage of about four between your hand and the small piston only.
    Now, the surface area of the large piston is about thirty times larger than that of the small piston. This where "hydraulic" advantage is obtained. So, the total advantage is 30 x 4, or 120. Lifting a 2,000 pound car requires 17 pounds. If a bottle jack was just a mechanical lever, no fluid would be needed.

    Thanks much for an excellent video clip. It gives the best explanation for how a hydraulic jack works.
    I have two such jacks that have failed.
    Can you advise what is the most common cause of failure of hydraulic jacks and if they are easy to repair.
    Thanks again for any advice.
