Please see my other video ( th-cam.com/video/mWD3TvXOU0c/w-d-xo.html ) for an even EASIER way to fix chair cylinders. NO TOOLS! NO COST!
Too mechanically technical for my grasp of 'efficiency', but that's my handicap, not your (generous) gift.
Thank you. The other video doesn't use any tools so it might fit your needs better!
hi, is this you too? th-cam.com/video/K321OKkNPqs/w-d-xo.html
How about about using an old washing machine hose ,slice it up the middle slip on underdhair pipe then tape😮😮,maybe babee❤
This is indeed a family-friendly video from a real man and real dad doing dads stuff.👍👍👍
Thank you!
In a wasteful culture where people just buy things to replace things, your repair videos are a breath of fresh air. I applied your other zero cost simple fix and it worked!
Great! Thanks for the feedback.
I love the subtle humour and efforts to keep this family friendly !
Thank you and thanks for watching!
Why does this feel like those videos they made us watch at school, awesome vids as always David!
Thank you. I wouldn't know about videos; I grew up with film strips. lol
Good work David. Never pass a discarded office chair by the roadside even if it looks trashed the base may have a perfectly functional piston and many office/ gaming chairs share the same 4-bolt configuration under the seat.
That's a great tip! Waste not, want not. Thanks for watching!
Good advice, all my office style chairs are discards, even a $1000 Herman Miller, that only needed a new cylinder 👍
Take the trashed chair off, and you have a great start for an adjustable, rolling work table, just bolt a scrap piece of plywood on top, and Bob's your uncle 🤠
Straight to the point no faffing around explaining the dynamics of the cylinder
Why can't all how to videos be like this??
Thank you. Check out my more recent video (link pinned in the description) for an even easier way to fix the cylinder.
Your "one year later video" works just fine....congrats on doing a great job of evaluating the problem and working for the answer.....again nice going!!!
Thank you so much. Glad it worked!
the video was slow moving , and highly detailed for a small curiosity to fix my darned chair. However, The content it holds is worth every second of watching. I know now if my chair was completely at a loss or if it was repairable. What this brought me was hope. And that, is what the world needs a little more of! thank you.
Thank you for watching and for your kind words. It' can be a little slow. It's always a balancing act to match the video detail to the audience. When I made this one, the videos that were out there all left me wanting more. That's why I got into the weeds. I try to help by adding an index so people can jump to where they are interested.
This video was very informative. But more than that, I loved the early late 80's - early 90's aesthetic of it. The intonation of the narration, the music, and the general instructional video quality of it, absolutely perfect.
Glad you enjoyed it! The mid 80's was when I made my first training video; I guess I haven't changed much since then. LOL. Thanks for watching!
Hahahaha, family friendly! Thanks for posting!
You bet!
@@LifewithDavid1 We need the unedited non family version with Extra Swearing please. Things don't get repaired without a little curse and swear ! haha jk, but thanks for the Vid David!
@@solprovidermusic 🔴 What Is Islam? ⚠️
🔴 Islam is not just another religion.
🔵 It is the same message preached by Moses, Jesus and Abraham.
🔴 Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God.
🔵 It reminds us that since God created us, no one should be worshipped except God alone.
🔴 It also teaches that God is nothing like a human being or like anything that we can imagine.
🌍 The concept of God is summarized in the Quran as:
📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)[4] 📚
🔴 Becoming a Muslim is not turning your back to Jesus.
🔵 Rather it’s going back to the original teachings of Jesus and obeying him.
"I hope you appreciate my attempts to keep this a family friendly video". Something tells me there was a lot of blue air off camera, and understanably so. By the way, best explanation Iv'e seen so far. 👍
Thank you. I don't have a curse jar in the shop so It doesn't cost me anything when I have a little "trouble". lol
Thank you for presenting a repair, and not a replacement or kludge with a pvc pipe. Exelent video.
I hope the repair works. Sometimes the cylinder is so worn out what only replacement or a kludge will work. Thanks for watching!
Here is my elegant kludge fix I made: th-cam.com/video/5fS7NQbLAlA/w-d-xo.html
agreed! there's too many clickbait youtube "repair" videos that end up being "just buy another one"
This is VERY IMPRESSIVE! Great technical quality and content. I've been looking for this info for the past 2 weeks and now understand how this type of chair operates. Great job!!!! Many thanks.
Glad it was helpful! Thanks for watching!
Thanks very much for this video, David!!!! We've got a lot of chairs in our office just ending up in our stockroom and the junkyard, and some of them still have repairable cylinders.
Glad it was helpful!
I wish I'd seen this last week. I searched for how to fix a chair gas cylinder and saw several other videos how about how easy it is to replace a gas cylinder. Even bought a pipe wrench to "give it a little twist". It is not always as easy as they show. My old cylinder is in 2 parts, there are shards of metal all over and I've cut myself 3 times. Turns out all I needed was a little oil in the right place. This video didn't even come until I searched google for "where is the gas in a chair gas cylinder" because I was thinking about cutting it out. So nice to find a straight forward informative video.
I wish TH-cam would get this out to more people. Sorry that it didn't show up right away.
Great job, David! Love videos like this that are instructional AND informative.
Thanks and thanks for watching!
Very nice video, i appreciate the work you have done.
Thank you!
Thanks a lot. That was exactly the video i need right now. No bling-bling, no bla-bla. Plain informative and well put together.
You're welcome. Check out my other video for an even easier fix.
th-cam.com/video/mWD3TvXOU0c/w-d-xo.html
What an excellent video! Very informative and easy to understand - thank you for taking the time to explain this, it helped me fix my sinking office chair!
You're welcome. Thanks for watching.
showing that punch work that way was exactly the advice I needed!
Great instruction. Thank you for the time and effort you took to make this video and share it with us. Greetings from Croatia.
Thank you very much!
Thanks for such a well presented video. It got me thinking that maybe the rubber seals inside the tube dry out and harden over time. If that's the case the addition of a little bit of stop leak like ATP AT 205 mixed with the jack oil may add more time in between servicing. This type of product is used to rejuvenate seals and restore elasticity to seals within engines, transmissions, hydraulic jacks etc...
That's a good idea. The reason I use jack oil is that it does have some seal rejuvenating properties. The additive might help also, however if the seal is that far gone, you might not be able to bring it back. Thanks for watching!
Fair point. I used ATF as I didn't have any specific hydraulic fluid to hand. I've been running ATF in my motorcycle primary for years without any adverse effects on the shaft seals.
Thank you so much it was a well produced video😊...
Keep making...💯💯
So nice of you
I always use a pipe wrench to twist the cylinder out of the chair. Works every time 👍
Thanks for this great video, I always wanted to know how these things worked.
Best wishes for your continued success ☮
I wondered about that. I was concerned about damaging the outer cylinder wall so I tried less aggressive methods (like beating on the end with a hammer is less aggressive lol). Thanks for the suggestion!
i needed this for a uni project and u practically saved me! thanks!
Glad I could help!
I have been looking online for a solution until I gave up, now this is the online video on youtube that fixed my issue! Thanks a lot!
I'm glad it helped. Check out my newer video for an even easier way to fix the chair cylinder.
Thanks for taking the time to share this video. I just moved into an office where ALL the chairs have this problem.
You're welcome! Like I've said a few times, I've found out since this video was posted that sometimes simply flipping the chair upside down and cycling the wheels up and down will do the trick. Although it's a little awkward, it's worth a try.
Finally a useful video. I wanted to replace the cylinder, and here I found a practical guide to how remove both the base and the cylinder. All other videos just show "bash the base with a hammer and unscrew the cylinder with a wrench, and everything comes loose." It did not. This one helped me solve the problem. Thanks!
Glad it helped. Thanks for watching!
I'm just a software developer who doesn't know anything about mechanical parts, trying to fix my chair. This video is really interesting
Try my newer video first, it's even easier.
Best chair repair video on YT. thanks man!
You're welcome! Thanks for watching!
Not only a proper repair video but also an explanation of the mechanism with great CAD drawings.
Will try it this week.
Thank you
Try my easier method first. th-cam.com/video/mWD3TvXOU0c/w-d-xo.html
Thanks for watching!
@@LifewithDavid1 will do :)
Really appreciated this video since my new chair is stuck in the down position. This video taught me how the mechanism works so I can troubleshoot accordingly. Thanks!
Glad it helped. Stuck in the down position is not good; it probably means that the cylinder has lost pressure. I'm afraid the fix is to replace the cylinder. Good luck!
I can't wait to retired.....I can imagine the amazing smell of your garage, the old paint rusted nails...David you are the men !!
Very informative and professional. Thank you sir
So nice of you. You're welcome.
Thanks David, this was indeed very helpful!
Glad to hear it! Thanks for watching!
Nicely Done! Thanks for the helpful tips.
Glad it was helpful!
Great video, honestly. Useful and well made.
Glad you enjoyed it!
Great Video! Helped me understand the workings of a pneumatic cylinder! Thank you sir!
Glad it helped. Thanks for watching!
Good ,practical and easy to understand video. Thanks.
Glad you liked it.
Thanks a lot! It's interesting to understand some of the science behind the problem.
Glad you enjoyed it!
Superb,got two of mine with the sinking feeling so i'll give this a go,many thanks.😁
Check out my more recent video for an even easier way to fix them with no tools. I pinned the link at the top of the comments.
I felt like I was watching my dad make that video, humor and all, including equipment meters etc. Handyman comes Sunday and hoping he can help me. This video will also surely help immensely. Thank you!
Maybe my newer video will make it easier: th-cam.com/video/mWD3TvXOU0c/w-d-xo.html Good luck!
Great explanation as always!
Thank you!
Many thanks for a clear description of how this mechanism works.
Glad it was helpful!
Thank you for an explanation of how the mechanism works and all the tips!
Thanks for watching!
this was very easy to follow thank u, keep up the good work
You're welcome!
This video lifted me up. Thanks 😁
Ha! Thanks for watching!
Always wondered what was up (and slowly sinking), great video!
Glad you enjoyed it!
Great video David !!!
Thank you! Hope it helped.
Learned something new today, I'm new to your channel from Bangladesh.
Thank you very much for sharing your knowledge with us.
So nice of you. Thanks for watching.
This is the video I needed. Thank you so much for the knowledge!
You are so welcome!
Thanks so much for creating this! It was easy to follow, and very informative! I was preparing to purchase a new hydraulic lift for my bar stool, but the black ones cost as much as a new stool. Naturally, stainless steel are half the price since that’s not what I need lol. I’m hopeful that this will be a cheaper fix!
Check out my more recent video for an even easier fix. Thanks for watching! th-cam.com/video/mWD3TvXOU0c/w-d-xo.html
Thanks for sharing your video. It was very helpful. I'm about to replace the cylinder on my desk chair. I'm hoping for joy!
Good luck!
This is awesome! Thanks, I'm going to try this step. Thank you
Hope it helps. Thanks for watching.
great effort, thanks for the video
So nice of you. Thanks for watching!
Excellent video!
Thank you. Hope it helped.
The video was still interesting to watch after the first time I was really able to grasp how the cylinder works, thank you so much for teaching me, currently in the middle of a repair of a gaming/office chair and I didn't get not 1 month of it before it started sinking so I'm really hoping this fix will do the trick so I don't have to sit there and readjust my chair every 2 minutes thanks for the video again and best of luck to you
You're welcome; thanks for watching!
@@LifewithDavid1 ended up doing a double whammy with power steering fluid and wd 40 works like a charm
thanks, it was hard to find information on such a repair
You're welcome Check out my more recent video for an even easier fix. th-cam.com/video/mWD3TvXOU0c/w-d-xo.html
Thanks for the informative video!
Glad it was helpful!
Great video! Fixed my chair! Thanks!
You're welcome. Glad it helped!
Great video, this explains the problem clearly, thank
Glad it helped
@@LifewithDavid1 and it worked! Thank you ☺️
nicely done sir! Thanks!
Glad you liked it! Thanks for watching.
Perfect, look forward to repairing the 3 swivel chairs I've accumulated before selling them to a new owner. Thanks David!
You're welcome. Thanks for watching.
Thanks, my friend! That helped me understand more about what I was doing wrong in removing the cylinder - I was dead-set on using the hammer method.
You're welcome! Thanks for watching.
Very well done video.
Thank you and thanks for watching!
Thank you for this very helpful video
You are welcome!
Having an issue with mine and have to admit i have seen quick 5 mins temp fixes but think this will be my long term fix thanks for the video David
You're welcome. Good luck.
Thank you! You earned a new subscriber!
Awesome, thank you!
Greatly informative thank you
Thanks for watching!
Thanks for a reasonable fix! I found that twisting with a pipe wrench dislodged the cylinder nicely. Took one person holding the chair and the other on the wrench but it worked!
Glad it helped
Twisting with a pipe wrench is in my opinion very bad idea. These was an boom accident and it was scary.
After reading some of your replies, David, I just turned my chair upside-down and cycled the piston a dozen times (to redistribute the original oil as you suggest). It seems to have worked! Thank you! No dismantling at all.
Fantastic! Glad it worked. Thanks for watching.
I found that out the hard way, lol.
Wow this seems to have totally fixed mine. Thanks for the comment.
This worked for me too. Chair would sink completely over 5 minutes of sitting. Cycled 15 times slowly upside down. No more sinking. Thanks.
Such an informative video
Glad it was helpful! Check out my later video for an even easier fix ( th-cam.com/video/mWD3TvXOU0c/w-d-xo.html ).
Super great video. Thumbs UP!
Thank you. Glad you enjoyed it.
I have a chair that I find extremely comfortable but it has a problem of slowly dropping down after several hours of use. In the past, I tried finding a video on how to address this but everything seemed to be on either replacing the cylinder or clamping it so it can't move up or down. I was reluctant to attempt to disassemble it because I was worried about energy stored in the gas. I hate throwing things into the landfill so I was happy to stumble upon this and the newer video. Thanks for the clear instructions.
Hope this will be the solution you need. Thanks for watching! BTW, there isn't much gas in the cylinder. Use common sense and you will be OK if you have to replace the cylinder. I think the biggest issue is if the cylinder leaks (highly unlikely) the gas could hurt your eyes. Eye protection is a must.
One of the best intros ever, well done Sir, just the laugh I need .
Thanks. Laughter IS the best medicine. Thanks for watching!
@@LifewithDavid1 It really is. It was a pleasure
Thanks for explaining how they work so well
Glad you like it!
very helpful! may this vid reach those having problems with their gas lift chairs.
Thank you. I hope it helps lots of people.
It is unbelievable how many "repair" videos I had to sift through before finding someone who _actually repaired the cylinder_. Thank you. TH-cam is truly frustrating.
Thank you very much for your kind words.
Sir David Salute for your efforts. Very goood video.
So nice of you. Thank you!
Nice video!!! Keep up the good work and the chair too. o7
Thanks, will do!
Great work... Thank you....
You're welcome. Thanks for watching!
Great explanation of the mechanism and the fix! You had mentioned you had done this fix previously, is this likely to leak oil over time? Mainly concerned about making a mess of the floor under the chair.
Thank you. I haven't had any leakage during the several years I've been using this chair.. I did clean the rod after I lubricated it.
Excellent!!! Thank you sir!!!!

Thank you, David. This hack is really a genius one. Being able to take a look at the internals, makes all the difference to understand the mechanism.
Check out my newer video; that is even easier. Thanks for watching!
@@LifewithDavid1 Thank you. 👍
My chair hydraulic hasn't degraded to the point of needing this repair but when push comes to shove I got your video to fix it. Thanks a lot sir.
Thanks for the kind words.
great information, really help gretings from Guatemala
Thanks for watching!
there are the videos I miss from when TH-cam was young.
Thanks for watching!
Thank you, I didn't do as much as you and even heard some nut or bolt fall that I never found and it still works perfectly
Glad it helped. Thanks for watching.
Great video. 👍👍👍
