How To Remove Office Chair Cylinder? [Follow These Steps]

Replacing a chair’s cylinder is not a tough job and can be done easily by a newbie as well. But first, a thorough test should always be conducted before replacing your gas cylinder. In order to avoid throwing away good gas cylinders, this step is vital.

1. Check your Cylinder

When you sit, the cylinder will sink all the way to the bottom if you haven’t adjusted the lever. Occasionally, a lever can be too tight to the point that it presses down on the lock even if no finger is placed on it.

The screws on your gas cylinder may need to be tightened if it’s not the case. In a cylinder with loose screws, the pressure will not be able to last long.

It is likely that the lever is not working properly if the cylinder is not sinking down when you press the lever. Additionally, you should check that your cylinder head’s lock is functioning.

You can proceed to remove and replace office chair gas cylinder if it still causes you problems after testing it.

2. Removing Your Cylinder

In just a few minutes, you can remove cylinder from office chair.

To get started, remove the casters, or wheels, from your chair’s base. This is achieved by pulling each one out individually. Tap gently on the bottom of the bottles until they come off with the rubber mallet if they are stuck.

Gas cylinders do not have to be removed by removing the casters, however, it is safer to do so.

After this, you must unscrew the four bolts which you will find at the top that is attached to the mechanism below.

For a better angle with your wrench, you can flip the chair upside down. This should be done on a smooth surface to ensure you won’t scratch the cushions of the chair.

As with removing the base, the procedure of removing the mechanism from the cylinder is similar.

Turn the cylinder upside down this time, and hold it with one hand. To release the mechanism, tap your rubber mallet on it using your free hand. Make sure that you tap it very gently.

Mechanisms are generally more difficult to remove from cylinders than their bases. Applying a little heat before tapping with a rubber mallet may help loosen a mechanism if it gets stuck.

If the mechanism still won’t come out then you may take help from a special removal tool. These tools generally come with your replacement cylinder.

3. Replace Your Chair Cylinder

Let the mechanism fasten up by sitting in your hair. This will take some time to work properly. The chair will be now in working order. It is now your choice as to how you want to adjust the seat.
