Want to fix your leaking floor jack? If so, you’ve landed at the right place.
A floor jack is an essential tool for mechanics and car enthusiasts. It is a hydraulic device used to lift vehicles for maintenance or repair. However, a floor jack that leaks down can be a safety hazard and render it useless.
In this article, we will guide you on how to fix a floor jack that leaks down in 7 easy steps.
How to Fix a Floor Jack that Leaks Down
Step 1: Identify the Problem
Before you start repairing your floor jack, you need to identify the problem. A floor jack that leaks down can be caused by a damaged piston seal, worn-out O-rings, or low hydraulic fluid levels. Check the hydraulic fluid level by locating the oil filler plug and unscrewing it. If the oil level is low, fill it up with hydraulic jack oil to the recommended level.
Step 2: Release the Pressure
To fix a floor jack that leaks down, you need to release the pressure. To do this, raise the jack saddle to its highest point and turn the release valve counterclockwise until the saddle lowers to the floor.
Step 3: Remove the Oil Filler Plug
Using a flathead screwdriver, remove the oil filler plug on the side of the hydraulic jack. Drain any remaining hydraulic fluid into a container.
Step 4: Remove the Plunger
To remove the plunger, loosen the bolts holding it in place using a wrench. Be careful not to damage the plunger or the cylinder while removing it.
Step 5: Replace the Piston Seal and O-rings
Inspect the piston seal and O-rings for wear and tear. If they are damaged, replace them with new ones. You can buy replacement parts from your local auto parts store or online. Install the new piston seal and O-rings by sliding them onto the plunger.
Step 6: Reassemble the Hydraulic Jack
Reassemble the hydraulic jack by inserting the plunger back into the cylinder and tightening the bolts using a wrench. Fill up the hydraulic jack with fresh hydraulic jack oil until it reaches the recommended level.
Step 7: Test the Hydraulic Jack
After reassembling the hydraulic jack, test it by raising and lowering the saddle. If it no longer leaks down, you have successfully fixed your floor jack. However, if it still leaks down, you may need to repeat the process or seek the help of a professional mechanic.
