Repairing GIANT Hydraulic Cylinder | Part: 1

Repairing giant hydraulic cylinder with some leaks and stracthes. In this first video we disassemble the thing and there are some really tight bolts that need giant wrench, bolt gun, really long steel pipe, torq converter and much more of tools

Please don't try the work methods seen on the video at home! We are experts with long experience and know what we are doing, expect when the broom is on fire :D

I had opportunity to document this magnificent effort from our brave team for your viewing pleasure! I didn't have super much time to polish the piece on editing table but it has it's moments thats sure :D Hope that you like it!

I didn't realize how much I was missing these workshop videos until I watched this one. I know it's a ton of work, but I know there are some of out here that really enjoy it!

Nothing like watching people doing honest work 😅

“Something to always think about when heating things that have oil in them: can it explode, and how bad is it going it be?” 😆 thanks Lauri

No polishing of the video is required, we love the content just like this. Please continue these whenever you want. Kiitos!

My late father was an orchardist growing apples, pears, apricots, peaches & cherries in Canada's Okanagan Valley in the late 1940s ~ 1970s. He had a large pipe wrench the same size as the one you were using at 09:30, but its handle was bent ~30 degrees from routine use of a pipe extension about 3 m long just as you did. Buried 3" [76 mm] steel irrigation water pipe vertical risers can be difficult to disassemble when rusty. He & my uncle used heavy chain & a Ford 9N orchard tractor to pull on the pipe that extended the wrench handle. Great fun to watch as a six-year-old boy. Thanks for the video!

I crack up and laugh every time that he uses the phrase "That's not optimal" - it is always preceded by the absolute worst outcome that could possibly happen, however he delivers it in such a dry mater of fact way that it always catches me off guard. Loved the video - great content.

As a millwright, I've run across many different situations where a bolt and nut, or bolt inside a housing gets seized. I've always had better luck heating up the nut to make it expand, or heating up the housing for the same reason. If Locktite is involved, it will melt and break free. The bolt will come loose with much less effort once you allow everything to cool off. If it still gives trouble, just heat up the nut or housing again as quickly as possible, then try and get the bolt loose before the heat transfers to it and makes it expand too much. 95 percent of the time this has worked for me much better. Heating up just the head of the bolt is just asking for trouble

The bolts ARE the stars of the video. Pretty astounding

[PeterPan-mynb]

That socket was the real MVP! Nice video.

If you ever have to do this again it might be worth taking out every other bolt so that you're keeping some pressure evenly clamped around the ring. When you remove them all in a line you could be adding a pinch stress to some of the other fasteners.

Really appreciate these types of videos. This is what we like to see, the working of your shop and crew. Many times I find that I understand what is being said even though I only speak english. I appreciate seeing families working together. Thank You.

Wow, that was super interesting to watch, thank you for filming the process. At least to me it seemed like you had all the right tools you could wish for this job, but the bolts still only barely wanted to come out. This really shows nicely how parts like a hydraulic cylinder become incredibly more difficult to work with the larger they get.

[herbertsusmann]

Very interesting job for sure! Dealing with such big pieces of steel that have been bolted together probably for years and years. Not an easy job.

"and know what we are doing, expect when the broom is on fire"

Relateable :)

Good effort folks, Cutting Edge Austrailia just did something similar - those cylinders are hard work.

[magman]

It's been awhile since I watched your videos and I can definitely say this one is bringing me back I love it and thank you for all the hard work you do

[ChicagoRaisedMe]

I'm a forklift technician from Chicago and this repair is something I do fairly often but not on a cylinder as large as this. It blows my mind that it is the same concept with smaller cylinders to bigger they still have same components. Seals, o-rings wiper seals etc.... Great job gentleman...Cheers from Chicago

[killermonkey]

Thank you for doing this I really enjoy watching these videos when i was younger i use to watch stuff like How it's made and building documentaries this takes me back really
appreciate this.

I LOVE Super Heavy Duty industrial tools and equipment. It's fascinating how much power you need sometimes to just break away a bolt, it's just amazing!
