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!

[@shanomac69]

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_Forge_Master]

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.

[@tracylemme1375]

I have been dealing with many similar situations, and I agree completely.

[@malachy1847]

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 ' ...

[@PHOBOS300]

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

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.

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.

[@indivisible885]

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!

[@GermoV]

The cooling down is a important part of getting it loose

[@garymurt9112]

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.

[@indivisible885]

@@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!

[@marcusfrancois5024]

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!

[@zviper]

I also would like to add giving the head of the fastener a good whack towards the threads with heat works very well

[@DMSparky]

They are extremely experienced machinists that regularly work on large equipment… I am 100% sure they know both of those things.

[@ehsnils]

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.

[@marcusfrancois5024]

@@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.

My first thought was that heating bolts would make them thicker and tighter, but it made sense when you said it made them longer, interesting. The smoke looked very cinematic too 10:46

[@GrandePunto8V]

This shows that most people don't understand how a bolt works (why it "holds" things)! Scandal! Presented method is very basic: heating up the head elongates the bolt, releasing some tension. Good method to save the expensive parts, housings, castings, cylinders, whatever. Cheaper to replace the bolts than fix the cracked, annealed, overheated, warped parts. Plus pounding it with hammer like a monkey.

[@sypernova6969]

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,...

[@jamesMwebber]

Next time you guys have a really stuck bolt and are using heat one way I found that works extremely well is to heat the bolt let it cool and repeat the process again and on the 3rd time let it cool slightly but still good and warm. What this does is helps the heat to penetrate the steel deeper than just one heat cycle. This works well on extremely rusted bolts also. Also helps to save the drive surfaces from becoming marred or misshapen.

[@benwinter2420]

As noted before if not a loctite type situation where heat needed to loosen that grip , but if corrosion only a few cycles as you say of heat & then a cold dousing immediate do loosen the grip too

[@mephInc]

As a mechanic at a blast furnace: That's a cute cylinder :) Love the vids btw.

[@brynyard]

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).

[@JokerInk-CustomBuilds]

Man, you really needed every trick in the book for this one! LOL

[@liberatetheforks]

Isn't it recommended to remove bolts in a star formation not circle? It may have increased the tension as one side opened and the other is stuck.

[@martin09091989]

Doing a star pattern has nothing to do with the tension of the bolts themselv. You do this if you have a fragile or very wide housing with pretension from like a gasket so you don't warp the part, or if you pull in a tight slip or press fit so it dose not pull crooked. In this Szenario, the barrel is very sturdy and ther is no prelode betwen the parts because they are butted against each other and sealed with O- rings. The pretension in the bolts are just so they don't first stretch when you put 400bar of pressure betwen those parts and ruin your day. 😅

[@GrandePunto8V]

If there is a pre-load in parts like covers, manifolds, flanges, the tension will mostly release when you undoing the bolts. Car wheel is the same - when the bolt is hard, try next one and so on (eventually they will all release).

[@bmxscape]

@@GrandePunto8V i think u got it back asswards bud. if theres a tight bolt, removing the bolt right next to it will make it even tighter. its like the spokes on a bicycle wheel. you break one spoke, what do you think happens to the spokes right next to it? they end up with higher tension

[@teeanahera8949]

New seals will cost little compared with a new barrel if they need one. If the barrel is chromed and may not be able to be fixed. Any gouges can’t just be honed out either as the internal diameter would be out of specification.

[@RustyDockLight]

That bit when the music started 🤘. That was badass!

[@Cargohold]

As a product technician of the assembly of hydraulic cylinders I am actually surprised your initial idea was not to heat the bolts up before disassembly. Usually there are hefty amounts of loctite on those threads because you ideally do not want them to loosen once the cylinder is in use. From what I can see, they also did not have a set screw or additional mechanical locking design. Thereby, loctite being even more important and the perhaps only way to disassemble those bolts would be to heat the glue.

[@x808drifter]

You also don't heat the bolt. Metal expands under heat. You want to heat AROUND the bolt not the bolt itself. The fact that he doesn't know this simple fact is both surprising and sad.

[@them0leisback]

​@@x808drifterI think you didn't get it. Bolt is under tension, if you heat it, it expands and reduces its tension. The longitudinal expansion is much higher than the expansion in diameter. Also, there is always some play between inner and outer threads, so as long as there is no rust heating the surrounding is going to make it worse. Most bolts, if not secured by loctite or rust, come right off with bare hands after you manage to snap or drill the head off, in example when the heads are rounded. Its mostly about pretension.

[@PHOBOS300]

@@x808drifter you heat the bolt. bolts are easy to replace, cylinders like that are not.

[@GrandePunto8V]

Dear "technician", you need more experience. Loctite alone will not cause so much trouble. These were old seized bolts (installed dry and rusted). Heating up the part (housing, casting, whatever) is always risky (cracks, warping etc.). It's way safer to heat up the head, to elongate the bolt and release some tension (this is how a bolt works). Heating up the threads area will not help much in this example (plus mentioned risks). Bolts are way cheaper than cylinder like that.

[@nicozenduro9988]

Great workshop video! Fight with the stubborn bolts is always epic!

[@zzota]

It's not the bolts that need heat; they'll just expand and get tighter. If you can't heat the whole flange, a better idea it to heat the bolts and cool very quickly. The shock can loosen them and the heat can burn off any locking agent. Another thing is, once you have removed a bolt, clean it and grease it and put it back. Keeping the flange evenly tightened can reduce the pressure on un-loosened bolts. Once they're all loose, undo evenly and remove.

[@teeanahera8949]

Good advise, same deal when withdrawing the cylinder rod as it didn’t seem on the same plane as the head contraption.

[@Sup3rman1c]

I doubt you've been taking any stuck bolts out. I know in theory you should heat the exterior threads, but in reality just heating the bolt will do, after it heats up just wait for the temperature to settle a bit.

[@GrandePunto8V]

That's getting boring! Another batch of lames. Everything wrong. Heating up the bolt will elongate it, releasing the tension (that's how a bolt works, holds things). The goal here was NOT to upset the piston, housing, flange, whatever, by heating up "everything" and pound with sledge hammer like a monkey. Bolts are cheaper to replace.

[@pokineusz3501]

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 :)

[@Cylopasm]

It's best to actuate the impacts in short bursts. Impacts offer the most breaking torque in the first 3 seconds. Continual driving after that has a significant drop off of breakaway torque.

[@martin09091989]

That is due to the pressure drop in the line, if you have big lines that is not much of an issue. I have a 15mm hose and a 1" ring pipe and the bigger couplers in my shop, if you have a such a stuck bolts you can just hold on to it and stip threads if needed. If I put the wimpy 8mm spiral hose in between that drop of is very noticeable and you just see movement in the beginning like you described.

[@Cylopasm]

@@martin09091989 While the available air pressure is one of the factors causing break away torque drop.

Using the impact gun and a pipe wrench at the same time was a good idea, maximum torque! You both hanging on that pipe reminded me of that time when I was trying to bar over a locomotive diesel engine that hadn't ran for maybe 40 years, and that after a diesel soak for 3 weeks. I was literally deadlifting on that bar which was about the same length as yours and just managed to bend the pipe which was 60mm dia. and 5mm wall thickness, that engine didn't move at all. Later we disassembled it one piston at a time with a lot of effort.

[@cr10001]

Yes, I once tried with a 1600cc car engine that had sat for a while. Pistons were well stuck in the bores. There was absolutely no way it was going to turn over. So after taking it apart and lifting the crankshaft out, the pistons drove out individually with a hammer and wood block relatively easily.

Lol this reminds me of working on the US Pacific Naval fleet in the late 2000's, I was trying to remove some 2" diameter bolts from a giant mooring line stanchion on the USS Shoup (a destroyer) and ended up having to take a rosebud torch to it on top of using a 15 foot long piece of steel scaffolding tube as a cheater bar to break it loose, my 350lb Bulgarian coworker and I had to put all our weight and strength into that bar to crack it loose. We busted a 1" ratchet extension and the handle on a 1" Proto ratchet wrench in the process, I've never seen a bolt so seized up in my life lol. The rosebud was what finally did the trick, heat is the best thing for a seized bolt.

Nice, great to see also the "normal" work in your shop when you're not friction welding hammers or making tools for the press to squeeze playdough 😀 This cylinder seems to be a real sucker. Even better to see that you still conquered it.

Excellent video, I hope you do film the repair and reassembly. Always nice to see Timo as well.
