How to Fix a Hydraulic Floor Jack

If you own a vehicle, chances are you have a hydraulic floor jack in your garage or trunk. These jacks are essential for lifting your vehicle off the ground for maintenance and repairs. However, if your jack is not working properly, it can be frustrating and even dangerous. In this article, we will walk you through the steps to fix a hydraulic floor jack.

Step 1: Identify the Problem

The first step in fixing your hydraulic floor jack is to identify the problem. Check for leaks in the hydraulic fluid or cracks in the cylinder or pump. Also, make sure the release valve is closed and the jack is properly lubricated. Once you have identified the problem, you can move on to the next step.

Step 2: Drain the Hydraulic Fluid

To fix your hydraulic floor jack, you will need to drain the hydraulic fluid. This can be done by removing the fill plug and the release valve plug. Once the fluid has drained, clean the inside of the jack with a rag or paper towel.

Step 3: Inspect and Replace Parts

Inspect the cylinder, pump, and other parts of your hydraulic floor jack for damage or wear. If any parts are damaged or worn, replace them with new ones. Be sure to purchase parts that are compatible with your specific jack model.

Step 4: Refill with Hydraulic Fluid

Once you have replaced any damaged parts, refill the hydraulic floor jack with the recommended type of hydraulic fluid. Be sure to fill it to the correct level, as indicated in the owner’s manual.

Step 5: Bleed the Air Out

To ensure your hydraulic floor jack is working properly, you will need to bleed the air out of the system. This can be done by pumping the jack handle several times with the release valve open. Once you feel resistance, close the valve and pump the handle a few more times.

Step 6: Test the Jack

After bleeding the air out of the system, test the jack to make sure it is working properly. Place it under your vehicle and lift it off the ground a few inches. If the jack is working properly, it should lift smoothly and hold the weight of the vehicle without any issues.

Tips for Maintaining Your Hydraulic Floor Jack

To prevent future problems with your hydraulic floor jack, it is important to maintain it properly. Here are some tips:

  • Regularly inspect the jack for leaks, cracks, and other damage
  • Keep the jack clean and lubricated
  • Use the recommended type of hydraulic fluid
  • Store the jack in a dry, cool place

Conclusion

If you follow these steps, you should be able to fix your hydraulic floor jack and get back to using it for maintenance and repairs on your vehicle.
