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

[@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

[@samvandellen3695]

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.

[@Scott00]

[@furionese]

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.

[@cr10001]

@@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.

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.

The bolts ARE the stars of the video. Pretty astounding

[@jrb_sland]

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!

[@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!

[@garymurt9112]

@indivisible885 they could of easily heated the area where the threads are.

[@Frank_inSA]

​@@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.

As an x-machine shop employee, I love to watch "How To" videos of machine shops in action, solving difficult problems with large machines.

[@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.

[@XFourty7]

[@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

[@joshuagibson2520]

Im glad you filmed this. Bring us more shop videos from time to time.

[@NightWolfx03]

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.

[@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).

[@orangedream267]

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.

[@commiellama]

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.

[@alfredm3785]

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!

[@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).

[@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.

[@StevenHess]

Love the job shop machinist stuff. Most people have no idea what it takes to keep industry running. Those are going to be some expensive seals. Getting those giant cap screw loose is going to cost the customer quite a bit.

[@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.

[@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.

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).

[@WookieeOfLand]

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.

[@WookieeOfLand]

@@martin09091989 While the available air pressure is one of the factors causing break away torque drop. This issue is still the case even for electric impacts like the monster Milwaukee they tried to use. There is a lot of information on how impacts behave on the Torque Test Channel if anyone is comparing or thinking of buying an impact.

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.
