How To Remove the Gas Lift from an Office Chair?

There are a few occasions in which you will need to remove the gas cylinder from your office chair. If the gas lift no longer holds your weight, or it doesn’t function as it should anymore, you will need to replace it.

Before replacing your gas cylinder, it is good to thoroughly test it first. This is to ensure that you won’t be throwing away a good gas cylinder.

Testing Your Gas Cylinder

If your gas cylinder sinks all the way to the bottom when you sit, try adjusting your lever. It is possible that the lever is too tight that it presses on the lock even when you are not touching it.

If that is not the case, try tightening the screws on your gas cylinder. Loose screws will not allow enough pressure to stay inside the cylinder.

If your problem is that the cylinder won’t sink down when you press the lever, you may want to check if the lever is working properly. You will also want to check the lock on your cylinder head to make sure it’s functioning.

If you’re still experiencing problems after testing your gas cylinder, you can then proceed to remove and replace it.

Removing Your Gas Cylinder

Removing the gas cylinder from your office chair is a simple task that can be done using just a handful of tools.

The tools you will need are an adjustable wrench  to remove the four bolts, a screwdriver  to remove additional locks, and a rubber mallet .

The first step is to remove the casters, or wheels, from the base of your chair. To do this, you simply need to pull each one out by hand. If they are stuck, you can use the rubber mallet to gently tap them downward until they come off.

Removing the casters is not required to remove your gas cylinder but it makes the process safer.

The next step is to unscrew the four bolts that connect the top of the chair to the mechanism under it.

You can turn the chair upside down to get a better angle with your wrench. Make sure you do this on a smooth surface so you won’t scratch up your chair’s cushions.

Once all four bolts are unscrewed, take the top part of the chair and set it aside.

The next step will remove the base of the chair from the cylinder.

Take the cylinder with one hand and hold it upright. Using your other hand, gently tap the base downward with your rubber mallet. Go around the entire base tapping it as close to the cylinder as possible.

When the base comes off, you can then proceed to remove the mechanism from the cylinder.

The process is similar to removing the base. Take the cylinder with one hand and hold it upside down this time. Then, using your free hand, gently tap the mechanism downward with your rubber mallet.

Removing the mechanism from the cylinder is usually more difficult than removing the base. If the mechanism seems stuck, you can try applying some heat before continuing to tap it with your rubber mallet.

Use a torch or hold it over a stove top. Be very careful when applying heat to the mechanism.

If you’re still having trouble removing the mechanism. You can use a removal tool that usually comes with replacement gas cylinders. Check out this replacement gas cylinder that comes with a special removal tool.
