- 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!
Lisää vaan! 👍
In USA we commonly call that a "Pallet Jack" or sometimes a "Pallet Truck".
Im super curious about the seal replacement on something this size.
Looks like a suitable piston for the clink cooler at my workplace.
@@WoodworkerDonin Finland we call them "Rocla" after the biggest brand.
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!
Same, I love the videos where he's doing, like... Conventional employment-type work using these machines for what they were actually designed to do. As much as I love watching things go squish, it's also really cool to see the machines work.
About three tons in this case.
@@jaakkoiswatching6437 ayyyyy
Me too
I can recommend you the Cutting Edge Engineering channel where guy does such repairs all the time with nice australian accent :)
I love these videos more than the 'destruction' things. Creating and repairing stuff is much harder.
satisfies the engineer mind!
Nothing like watching people doing honest work 😅
To be honest, I also like watching some people doing dishonest work.
what we need more in society!
It is hard work watching someone has to work so hard....
“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
Yeah, I was thinking the same: "So... you are saying that some explosions would be acceptable?"
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.
No polishing of the video is required, we love the content just like this. Please continue these whenever you want. Kiitos!
Timo: "Hey Lauri, have you seen my 5,000,000 mm Cheater Bar?"
Wow the pipe and impact at the same time was completely brilliant.. You are a genius.
I gasped when I saw that, definitely adding that to my arsenal of tricks
I was thinking the same "Why haven't I thought of this?" but then realised soon after that you don't really have situations where the bolt you're dealing with have BOTH the hex head shape AND female hex socket. You don't really see that kind of bolts on cars for sure, with phillips head yeah but not female hex socket. You usually deal with simple hex bolts you simply do away with hex socket or wrench or whatever but never Allen wrench for the inside hex and another wrench for the "outside", if you know what I mean.
@@furionesethese are just normal hex, pipe wrench don't need any flats to work
@@furionese Phillips head are the absolute worst, guaranteed to cam out. That's where an impact driver becomes indispensable. (I don't mean the type of air impact wrench they used here, I mean the hand-held tool where you belt the end of it with a heavy hammer and an internal spiral twists the bit at the same time the impact forces it into the Philips slot). It's also very satisfying that the more you belt the &^%*^%$% out of the sod, the better it works. And some Philips screws that have taken perverse delight in deforming and munging their slots are sufficiently intimidated by it that they come out like a dream as soon as you tap the driver.
Cheater bar with a helper hammering the bolt head is a perfect recipe for stubborn lug bolts so makes sense the combination worked here too
The bolts ARE the stars of the video. Pretty astounding
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
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
I was thinking the same thing. Heating _expands_ metals, so heating the bolts helped to give them the initial movement to break loose, but it also made them want to grip harder.
I have been dealing with many similar situations, and I agree completely.
Thinking that Heating up the Head of the Cap Head Bolt allowed the transition of heat into the bolt which grew, this allowed slight movement as the head which would have been under tension against the flange of that cap...there by that thermal expansion created less tension, allowing the combination of the Stilson plus a piece of box section and Air Hammer/ Driver to do its work....Obviously IF one had an Hydraulic Torque multiplier those suckers would have walk off... Heat may have changed the heat treat treatment already given to those set screws giving an annealing or normalising effect to same... as one would presume, some degree of Tempering or harding by quenching could have been carried out to same to give same the correct 'Grading ' ...
I don't think he got them hot enough, i always have the best luck heating the entire head of the bolt till its red, then work on something else, and come back after it cools down. particularly on steam turbine nozzle blocks
I would have put the torch in the head where the allen socket goes untill in was entirely red not just one side
the size of that cylinder would prevent you from really heating the whole thing like that, and its a lot easier to replace a bunch of bolts than a cylinder
also should have got a hytorc and some kroil
Completely right, shanom
Accidently set the broom on fire 😂
It's a miracle that only the broom was on fire with time swinging that torch :D
This really burns the broom!
One day, in the shop, one of my co-workers was carrying a broom. He saw me watching him, and said "I drove my wife's car, today." 😂
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.
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!
That socket was the real MVP! Nice video.
As an x-machine shop employee, I love to watch "How To" videos of machine shops in action, solving difficult problems with large machines.
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
HEAT.
BEAT.
REPEAT.
Works everytime.
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.
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.
Love seeing some more work from the workshop
"100L of oil on the workshop floor and that not optimal" Quite the talent for understatement
As he said it turned out to be about 40L and only a couple of litres on the floor.
Man, you really needed every trick in the book for this one! LOL
That bit when the music started 🤘. That was badass!
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.
This is the kind of videos I love! Honestly I dont watch the hydraulic press videos anymore
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.
As a mechanic at a blast furnace:
That's a cute cylinder :)
Love the vids btw.
I like the broom catching on fire! Things like that always give a good laugh out of nowhere :D
Timo was a bit careless with that flame.
THIS was cool as hell to watch. I learned a thing or two for when I need to remove some larger bolts.
More of this, please! I used to work for a farm mechanic, and have fond memories, and stuff like this is very nice to watch!
Im glad you filmed this. Bring us more shop videos from time to time.
Brilliant video Lauri. More of these, please!!
Sometimes i have this same situation,and ive had some success by heating the bolt, like you said, the bolt will expand and break the rust loose. So if you heat it extremely hot,then let the bolt cool down, it breaks free. But it does take a long time to get that much mass hot and then cooled back down.
I'm super grateful to see you film this, so people that don't deal with this kind of thing, get to see how large industrial problems, are solved, and the effort that goes into keeping the world moving!
The cooling down is a important part of getting it loose
The was heating the wrong end. They needed to be heating the Part that contained the threads. If you heat the area that has the threaded hole, the hole gets bigger. If you can apply dry ice to the bolt head at the same time the bolt will shrink.
@@garymurt9112 when heating to expand the hole can't be done, hearing to expand the bolt is the alternative! When you expand the bolt (which he eludes to) it breaks whatever corrosion is keeping it from losening. Believe me, I've had to use both techniques. When you can't apply heat to the internal threads of a hole, because of warpage, or distorting the threaded part, heating to expand the bolt is the only other alternative!
@indivisible885 they could of easily heated the area where the threads are.
@@garymurt9112if you heat the casing you heat the bolt too, it's like one part, doesn't matter if you cool the bolt head, the cooling does not really "penetrate" into the bolt. And if it does it cools the casing too again.
Your workshop videos are my favourite!
It takes me back to old days working with my dad on Lokomo and Timberjack machines, doing all this kind of stuff with rams and pumps and motors. Nice video.
Great workshop video! Fight with the stubborn bolts is always epic!
Very inspiring to watch your procedure.
"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.
Thanks Laurie. Brilliant bit of machinery that I often wondered about and many others have gone over the subject in conversation. None of us had a great deal of information about the guts of these large rams. And your co-host also "hello"
I appreciate this because there's a lot of good information on some things like dealing with stuck parts, it's nice to see that it came about without having to cut or burn the bolts out.
The best thing is to heat the area around the bolts to expand the material so the bolts can come out easier. And also hitting the housing with the hammer while your impacting the bolts can help too!
I also would like to add giving the head of the fastener a good whack towards the threads with heat works very well
They are extremely experienced machinists that regularly work on large equipment… I am 100% sure they know both of those things.
It makes sense from a thermal expansion perspective but the bolts are easy to replace while the housing is more or less custom made so you'd like to avoid damages to the housing.
I wouldn't be surprised it the bolts were secured with Loctite Red or something similar extremely strong. Heating the bolts would cause it to break down and allow the bolts to be released.
Recommendation for disassembly of LOCTITE 271 is to heat the material to about 250 degrees C and unscrew while hot. Just because the head is red hot doesn't mean that the thread is at the same temperature, so from that perspective this was probably the best way to go.
@@ehsnilsnope the housing is 10x stronger than the bolt is. I guarantee breaking a bolt off in there or even just stripping it off in there is worse than whacking the housing with a hammer.
@@DMSparky people learn new things every day.
I really enjoy the workshop stuff.
Thansk for sharing this. this is stufff htat regular people do not get to EVER see, and it's really interesting to see the machine itself, but also how you deal with the problems. regular people like me that only do littel projects once is a while have no idea how to solve some of those issues,...
I love the real work videos. Cutting Edge Engineering is a great example of how to cover big work in a shop.
Would definitely enjoy seeing the reassembly of this thing! Well done to you all and glad no one died taking it apart! 💪👍
Love the problem solving! Great work.
I'll be honest with you - I've already seen dozens of explosion videos, and while they are always very interesting, this video is not just an everyday stuff and I'd like to see more of it :)
Same kind of work we do at work. Love it!
More vids like this would be amazing! Sucks that they are so time consuming :(
The workshop videos are great! Keep them coming
I love seeing how different hydraulic cylinders are designed
As i work in a similar field i really enjoyed watching this video, thank you.
Excellent video. These make me miss my CNC Machining adventures.
I'm so glad this fall in my lap. Great video!!
Attualmente i love this video much more than the simple press videos, i think you have found the way to revive the channel!
This was an amazing video that really enjoyed watching. Your narration is great.
Cool! Always appreciate the workshop videos.
Man loved this, would love to see some summary of the work done and the reassembly.
Great video. Thank you. Fully aligned with enjoying the summer while it's with us. Plenty of time for work when the rain comes.
Really good experiment!
Great subject! loved it!
Great video, really enjoy seeing these interesting workshop jobs.
I loved this video! Don't be afraid to do more of these sort of behind-the-scenes of behind the Press of in the shop ugh the Press Channel. These are good
It's nice to watch hard work on a Sunday morning from the sofa at home, with a warm cup of coffee in hand.
I worked 35 years in auto shops and stuff on a much smaller scale i did this kind of stuff too, super long pry bar pipes, hammers, acetylene torchs, heavy duty pullers, nut crackers, super big impacts, a few licks clockwise, then lean in on it until the air compressor can’t keep up. I love working men, we helped and respected each other. You could really no get along with a guy but when it came to a team action everyone got in on it.
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!
Always cool to see a little of your real work on video
Really like this sort of video!
Would be very interesting to see how you fix scratches in the surfaces.
These kind of videos are very good.
Please try to show us more of the work in the shop.
Thanks!
Very interesting ! Thank You !
nice to see the rose bud coming out! most underrated shop tool
Looking forward to the reassembly videos
That hydraulic cylinder is incredible!
Impact tends to jolt the thread interface enough to loosen it, this is why impact drivers work so well in the first place :P
But combining high constant torque and impact (and heat) is usually the solution when you don't want to turn the bolt into a puddle (or dust).
Fun to see what you really do there. Thanks for filming that.
Pretty cool to see. Hell of a thing to try and disassemble.
It’s nice to see the learning curve in practice. And one thing is to take it apart, and another to put it back together…
this is the best video in times saw on your channel! I love this stuff!
Those are the reasons why we all like Timo, he casually sets the broom on fire ... :D
I once had the same problem trying to open a jar of pickles. I used the same equipment that you guys did and finally got it open.
Best bit of this video was Timo setting the broom on fire.
Excellent video. Those were tight bolts. I always enjoy your videos.
I really enjoyed this video. I know that you use your press for more than just smashing things. Myself, I like to see the things that the machine is made for.
This workshop stuff is quite interesting,, and this is a hydraulic ram so very apt!
This was fascinating
I love this content, so interesting and cool.
This was a really interesting video! I definitely want to see the assembly!
I do work like this all the time and appreciate you guy’s! your fun to watch not a lot of guy’s interested in this type of work hopefully videos like yours will inspire the younger crowd …
Yeah, they "inspire" army of retards who comment on how the video technique was "wrong". The "lames and squares" give "advice" to Pros - to just heat up the whole thing and cool the bolt and BS like that...
While heating the bolt elongated it and released most tension (video is 100% correct and practical).
That was super interesting to watch.
For anyone wondering about torque: when they had the pipe on there, 1lb/ft is linear. Two guys at 5ft is probably around 1000ft/lbs. Those bolts were tiiiiiight.
Very interesting. A world I'd never see otherwise.
Excellent video, I hope you do film the repair and reassembly. Always nice to see Timo as well.
This was quite interesting to see, looking forward to the next ep.
i like watching stuff like this. you should film more of your work.
very interesting! love your work!
very interesting, thanks for filming it
Very interesting. My son and I have had stubborn bolts but not to this degree. There is a lot of useful information here.
I enjoyed watching this. I hope there is a part 2 or 3 or 4.
I am from Milwaukee, great to see home town represented. And seriously love the channel. By the way, yours must be the most Finnish accent I've even heard. 😮 I'm impressed. All good things.
