Pipe wrench worked for me, slick as a whistle. I used a bigger wrench though. I had a harder time hammering the piston out of the chair base - I used a 5 gallon pail with the base inverted, and hammered it with a sledge and a wood block.
I've been struggling with this exact same problem. Using the same replacement cylinder kit and tool. Pipe wrench and PB Blaster has not worked. Maybe I'll try it again. A 25 year old, expensive commercial office chair.
@@richardlelandneal7888 yes, that's exactly what I did. Ended up getting a metal ring that flanges out. Fits perfectly over the cylinder housing and you just wail away on it while pulling up on the cylinder as the chair hangs upside down. Finally after a few bangs in different spots around the flange, it drops out. $16 on Amazon.
@@TheBigfoot567 Could you please link to the tool or maybe you recall what it's called? I've searched amazon and only find the tool that Richard has used here. Thank you.
@@letXeqX I found my purchase info on my Amazon acct, and attempted to pull up the item. Seems it's no longer listed. But I did message the seller and asked if they still had these available.
wow. god bless ya for stickin with it my man. im on hour 4 using that tool. the destructions say to keep both clamps as close together as possible. so far thats not working. i see you had yours gapped apart. im gonna try that next i guess
well, they push on each other but one needs to push against the chair and the other needs to be tight on the cylinder. If they don't move apart then it will not work
@@richardlelandneal7888 5 1/2 hours later.....success. so the instructions are indeed wrong to have close to each other. gapped them about 3/8" and drove the bolts down and it popped.
Thanks for this! I have an Autonomous ErgoChair that has been out of commission for months bc I couldn't get this thing out. Their video makes it look like a little love tap will release it, I've been hulk smashing it and it doesn't budge! Gonna grab one from Amazon. Ty again!
Thank you for your post. I had bought a new cylinder, stand, and wheels. I have watched several videos of replacing cylinder, and yours seemed the less hassle of all, I just ordered the tool, maybe you should require a fee for advertising. Good job
After using all the hints to remove the cylinder, which I’ve decided is welded, because there’s no budge. I’m gonna put the chair back together and use “banding” to hold the seat at the top position. At some point I’ll order a new chair, but it’s not used daily and I think the “hack” might be sufficient.😊
My new favorite reviewer. Love Richard's sense of humor. Love the buildup. The suspense, the feeling of hopelessness only to be flushed with elation as the piston pops off unexpectedly and instantly. I just bought one.
Well, I didn’t have the little ringey tool, but I took off the chair seat and mounted that base in a big vise and ended up putting a 4’ snlpe on a pipe wrench to twist the cylinder which came right out. I didn’t mangle the aluminum base but couldn’t get the other end of the cylinder out by banging on it with an 8# sledge, so I took it to my neighbor and used his 20,000# hydraulic press and it came right out. Re-assembly was a “snap”.
@@TheRazvancristian from what I gather they are, they have different weight capacities and a tool piston will be too tall, but a chair piston will fit in your chair most likely. You could measure it to be sure
