How To Repair a Floor Jack That Wont Hold Pressure
If your floor jack won’t hold pressure, it usually indicates an issue with the hydraulic system. Repairing a floor jack that won’t hold pressure can often be tackled with some basic troubleshooting steps. Here’s a guide to help you through the process:
Tools and Materials Needed
- Hydraulic jack oil
- Wrenches or socket set
- Screwdrivers
- O-ring or seal replacement kit (specific to your jack model)
- Cleaning rags
- Drain pan
- Work gloves and safety glasses
Steps to Repair
1. Inspect the Jack
- Check for Leaks: Look for hydraulic fluid leaking around seals, the release valve, or the pump.
- Inspect Components: Look for visible damage or wear on the seals, valves, or pistons.
2. Check Hydraulic Fluid Levels
- Low Fluid Levels: Unscrew the fill plug to check the fluid level. If it’s low, refill with the correct hydraulic jack oil and test again.
- Incorrect Fluid: Drain and replace the fluid with the recommended type if necessary. Using incorrect fluids can cause performance issues.
3. Bleed the Jack
- Why Bleeding Helps: Air trapped in the hydraulic system can prevent proper pressure buildup.
- How to Bleed:
- Open the release valve.
- Pump the jack handle several times to circulate fluid.
- Close the release valve and test.
4. Examine the Release Valve
- Faulty Valve: If the release valve is not sealing properly, the jack will lose pressure. Tighten the valve to ensure it’s fully closed.
- Replace Valve Components: If tightening doesn’t work, disassemble the valve and replace any worn-out seals or O-rings.

The majority of the floor jacks are built with a safety and security overload function. This will certainly stop them from working when the customer attempts to overload them. Attempting to exceed its ability will certainly likewise stress its system, resulting in minimized high quality and also a risk to its customers.
Inspect the weight of the truck as well as contrast it against the floor jack’s lifting capability. Normally, a 2-3 ton-capacity jack can raise traveler lorries as well as light-duty vehicles.
Some floor jack units include an overload or safety valve. This includes protection against accidental use. It quits lifting instantly on the occasion that the flooring jack has currently reached its maximum PSI degree. Nonetheless, some users, particularly newbies are puzzled about the filler port and also the safety valve. When this happens, it is best to describe the customer’s manual to look for aid from flooring jack specialists.
10. Inspect the hydraulic fluid level
Be it a reduced or greater liquid level, both extremes are bound to cause problems, as your training gadget won’t work correctly.
The liquid level should constantly be within the recommended limit, neither much more nor less than what’s needed.
When operating a jack with a higher fluid degree than regular, the greater than recommended stress risk burning out seals, triggering internal leaks, and leading to a jack that will not hold stress.
On the other hand, a jack with a low liquid degree will typically work fine, however, the optimum height will be dramatically reduced. The genuine worry right here is discovering why the fluid level decreased. Hydraulic systems operate in a closed loop, implying that the fluid level ought to never ever decrease. If it does, there’s possibly a leak someplace and also you’ll require to fix it before you can utilize your jack
How to inspect the liquid degree on a jack.
Inspecting the liquid degree on a jack is fairly easy. Just take off the fill plug as well as check the chamber for the oil level.
Different jacks may work in different ways so make certain to inspect the specs in the proprietor’s manual. Naturally, it’s not uncommon for jack owners to have lost or trashed the instructions after acquisition. Thankfully, there are many internet sites using jack repair service guidebooks around.

- Remove the oil fill screw from the training device.
- Return the shutoff to its initial position
Voila! The trapped air ought to have been pushed out of the system, so you can move forward lifting the automobile. If the condition is still the exact same, repeat the procedure a number of times extra.
