Help to remove Gas Piston from Gaming Chair

[Dragonfyr]

Hi there,

Anyone have any idea how I remove this gas piston from the under part of the gaming chair? It needs to be a safe way so that I can use the piston on another chair. It's secured to the mechanical part under the chair... the metal part that adjusts height etc.

Chair: Vertagear PL6000

Was going to post images but can't due to this being a new forum account

No idea for that specific chair, don't know if this video is any good :

It's usually a friction fit, so it gets pretty tightly pressed it on a well used chair.

To remove mine, I spray a little WD40, leave it for ten minutes and set the piston through a hole in my workbench so it is suspended only the "spider" and hit it with a hammer. Well, I cover the end of the piston with a bit of scrap wood to protect it before hitting it with a hammer.

The WD40 really worked - without it, I was thumping away for ages, the first time I did one, with no results.

Hi, thanks for replying so quick. This guy uses a hammer to smash the metal part that's causing the problems (like all other videos i've seen)... which i'm hoping isn't the only way to do it.

@ 2:47 ^^ on that video

Your options are press it out, assuming you have access to suitable equipment, or knock it out. If it's the latter, you will need a hammer.

The end of the piston that's fitted to the seat adjustment mechanism will likely be the hardest to release - you'll need a hammer and dolly - I have the bar from an old dumbbell that works just fine as a dolly, but (again) WD40 or some other kind of penetration oil/release agent will do most of the work for you.

I've have done this on my chair a few years ago, its not as easy as what you see on youtube. The tools i used was a pipe wrench, hammer and plusgas (penetrating fluid). What i did was turn the chair upside down, spray loads of plusgas on the piston connected to the chair seat, make a cuppa tea while the fluid penetrates, lay the chair on the side, grip it with the pipe wrench, wrap the pipe wrench handle end with a rag(so you don't get bits of metals flying off it) and hammer it really hard. This will probably take a long time as their maybe rust inbetween it. Have fun!

I drove mine our with a bit of old wood to protect the piston and keep whacking it with a mallet until it came out.

It always seems to be that metal bit just under the seat that fails, and the piston is a git to remove. Good luck
