## Description

desertcart.com: Office Chair Gas Lift Cylinder Replacement, Class 4 Hydraulic Piston | 4.7" Lift Universal Fit Pneumatic Chair Lift Replacement for Desk Chairs, Gaming Chairs, Executive Office Chairs : Industrial & Scientific

Review: WORKS FOR NOW - I received my office chair cylinder replacement quickly. I'm usually impressed by the fast delivery by desertcart and its vendors. I was cautiously optimistic regarding taking the old cylinder apart from the chair after reading reviews by peoples experiences. I' a good sized cro-magnum 6'3" 230 lbs and the chair had worked well 5 or more years so the cylinder was well seated into the chair frame and base. I had necessary tools pipe wrench, rubber mallet, WD-40 etc... watch a few videos before attempting to remove the defective cylinder, it will help and set some expectations. Put an old blanket or large piece of cardboard down so the WD-40 doesn't get on your floor or carpet or better do it in the garage. After spraying the chair base where the cylinder goes in to it, I firmly tapped each leg of the chair to start loosening things, then turned the chair over and beat it quite hard 8-10 times and the base of the chair came free. Don't be shy about banging on that base. Some videos suggested using a hammer to separate the cylinder from the chair back? not easy to do and a small surface to get at with a hammer. The disks provided with your new cylinder were a great idea. Start by getting some WD-40 around the cylinder. I put one of the round rings around the cylinder as close the the chair bottom as possible, using the longer screws provided, you use the allen wrench to tighten the screw till you feel it's quite snug, then do the same with the other longer screw. It is a slow process but each time you tighten the screw it is slowly pulling the cylinder away from the chair bottom. Be patient and just keep turning the screws in a little on each side. I was not able to use that process to remove the cylinder completely, but I got enough of it away from the chair bottom to use the pipe wrench to twist it enough to remove the cylinder. Don't worry about scaring the old cylinder up get the pipe wrench on it good and if you can't move it with one hand you can hit the wrench with a hammer or get another person to hold the chair bottom so you can use two hands and keep using the WD-40. Once the old cylinder is removed the rest the process is very easy. Put the chair base on the floor with the casters or wheels on the floor. Put the new cylinder in make sure the clip on the cylinder is pointed at the floor. On the other end (MAKE SURE YOU REMOVE THE BLUE PLASTIC CAP) on the top of the cylinder before putting the chair on top of the new cylinder very important. Once you've done that you should be good to go. As others have mentioned and in my situation, this after market cylinder is longer than original cylinder in my chair, it works fine but at its lowest point it is where my original chair would be at the highest point. Just depends how much leg room you have under a desk. One other tip I read was every week or two, raise and lower your chair to move the cylinder up and down, that will keep the cylinder and seals lubricated. Trust me I'm not an engineer, but that makes sense that leaving your chair in the same position for years the seals could dry out, you get a crack and lose pressure in the cylinder. OK Mates... sorry for the long review best of luck. In all it took me maybe 40 minutes to do this
Review: Worked Perfectly, Needed Stubby Hex Keys - During the pandemic, safer at home days, I started to notice that my posture was a little off and my lower back was starting to hurt. I then noticed that the chair wasn't in the proper position any longer and I was not able to raise it any higher. I knew immediately that I needed a new chair or the back pain would progressively start getting worse. However, knowing that desertcart sells everything, I decided to see if they sold just the cylinder replacement since a new chair would cost me about $200 (and my current chair was in really good condition other than the cylinder height). I opted to purchase this item due to it being a full kit as well as offering a coupon discount. When the kit arrived, my initial install try failed miserably. First, I was not able to remove the chair as I couldn't slip the hex key between the bottom collar and the stock plastic sleeve that covers the "unsightly" cylinder. I know I could've cut the sleeves off, giving me the clearance. But, I wanted to maintain the original look of the chair as much as possible. Second, no matter how hard I hammered at the bottom of the cylinder with the rubber mallet, it refused to budge and I couldn't get it to detach from the base. I even soaked the seam with WD-40 and let it sit overnight. Still, no movement at all. Try number two. I turned back to desertcart to see if they sold stubby hex keys, which I immediately ordered. Day number two, the stubbies were delivered and voila, fit perfectly between the collars and the plastic sleeves. Next thing you know, the chair was detached. I then turned my attention back to the base... I took the base and placed it on top of a five-gallon bucket and again, soaked the seam with WD-40. After an hour, I hammered the cylinder again with the mallet and to no avail. I finally turned to a metal hammer and used the side of the hammer to equally disperse the energy to the edge of the cylinder base. After a couple of strong strikes, the cylinder popped right out. Excitedly, I cleaned off the WD-40 from the base, installed the new cylinder on the base, removed the plastic button cap, and installed the chair. The cylinder worked perfectly and at its highest height, I couldn't even place my feet flat on the ground (and I'm 6'1"). This cylinder replacement, even with the stubby hex key set purchase, saved me about $140. For those who prefer a tl;dr version/tips: 1.) Buy a stubby hex key kit if the included hex key will not work between the bottom collar and plastic cylinder sleeves 2.) Remove the chair using the included collars 3.) Place chair base and cylinder upside down into a five-gallon bucket 4.) Hammer the cylinder through using the flat side of the hammer (or use a block of wood between the cylinder and hammer) 4a.) A rubber mallet was not strong enough

### ⭐⭐⭐⭐ Second revised review. Height adjustment problem corrected. MY BAD.
*by O***R on December 2, 2020*

1- The piston itself works great, is large and sturdy. An inch or two longer than the one that came with the original chair so if you are using your chair's lowest setting this may not work well for you. 2- The replacement tool works well enough and is not difficult to use if the piston you're removing is fully expanded. The chair I was fixing was several years old the old piston firmly embedded in the seat's mounting plate. I have an electric heat gun and with a little heating of the seat's mounting plate the old piston slid right out. 3- The instructions for the removal tool are terrible. Assemble the first collar right against the seat's mounting bracket. DO NOT tighten it to clamp onto the piston, it has to slide and rotate freely. Clamp the second collar directly below the first but DO NOT line up the holes between the two collars. Make sure they are offset and clamp the second tightly to the old piston shaft. Now when you tighten the long hex bolts through the second clamp it will press against the first and force the piston out of the seat's mounting plate. If you line them up you will only fasten the two clamps to each other. 4- The first time I used this product I found that the height adjustment did not work. I thought it was because the chair's adjustment rod would not press the adjustment button on the top of the piston. THAT WAS NOT CORRECT. It turns out that the piston is shipped with a small safety cap covering the height adjustment button at the end of the piston. It keeps the button from accidently being depressed and expanding the piston during shipping. You kind of need to take that off BEFORE you assemble the seat onto the new piston. When properly assembled the product works great but only gets a 4 star review. The product gets 5 stars, the instructions get -1.
