- This is a rare beast. A very expensive and specialized hydraulic actuator. It looks like a regular cylinder but it's hiding an interesting surprise. And not the kind of surprise you got when your Uncle Grandad first asked you to pull his finger.

This must be what those guys at quick lube shops use for tightening oil filters.
+hydrogen18 lost it at this. XD
+hydrogen18 Most of that is just not lubing the o-ring. I'd tighten the hell out of them, but I'd lube the o-ring, which resulted in me being the only one who could get them off, and after getting called into the pits whenever we had one of my cars come back to get the filter off, I ended up just staying down there forever. One of the tough-guy managers even chewed me out because a filter I put on was "stuck", but I could get it off by hand, but he wouldn't lube his.
Well drill two holes and stick your Chineseum-mild Steel facewrench in it.
Meh, these days I just throw a strip of sandpaper inside the strap wrench if I am unfortunate enough to have to use one of those things. I will go out of my way to get a proper socket for the filter if I can though.
As we idotic Germans are, we started putting fucking extra boxes for oilfilters, that can be opened with fucking normal wrenches or nuts and are tightened to spec with a torque wrench but not with the fucking note on the cap to oil the seal before putting it back together.
most useful thing about your videos: comments about what not to do and how to tell if you're in the middle of doing it: spitting out fluid? stop; find out where the pressure is. does not free up when unscrewing? stop; might be pre loaded. think how many fingers you have saved your viewers
betabenja Precisely. Thanks to uncle bumblefuck I still have both mine left
Yupp! Almost made the mistake of trying to open an relief valve for a 3in high pressure line. Half way through unscrewing a plate that surely had a beefy preloaded spring behind I remembered hearing "if it doesn't loosen up when unscrewing it might be preloaded" and realized my stupidity. En la basura!
Spot on. Captured large springs scare me more than high voltage, and as a maintenance machinist I encounter both regularly. You can put a meter on a line and check for voltage, you don't have a meter to tell you how much tension or compression is on a captured spring!
"if youre handed a wrench, that doesn't mean your qualified" Starts bashing it with said wrench while under 1500psi of pressure. Thats my guy
I liked it when the wrench slipped off and he then said it had reached the correct torque. Lol. I call adjustable wrenches 'nut f*^kers' for a reason!
You my friend have no idea
To be fair, he was smacking the 1 1/2" thick plate on the end that bolts to something. Not the thinnest part that holds pressure, like the walls.
10:35 Oh, how I love the "I lack the required tool. That means I'll make one" attitude. Engineers are unstoppable.
Nick Nirus * people who make their own. This guy ain't necessarily an engineer, and lots of engineers don't really think that way. People who think that way do, whatever their trade.
GunFun ZS Fair enough.
Nick Nirus I know engineers who work out of catalogues an CAD libraries. i.e. Aerospace guys for instance. They have to be able to document the failure rate of anything they work on, so "I made it work" will never fly. They buy something proven or don't make a move.
You'll find lots of welders, fabricators, mechanics, handymen, etc. Who make the tools they need.
Actually a lot of people get burned out as enginers because they like to create, go to school and never get to create. Their day job is to "draw out the thing we have been making for 100 years, but this time, do the math to see if we can get away with substituting this cheaper bolt..." or "put in all the locations for fasteners on this thing your boss got to create"
Small business owners are really the guys who tend to be in the magic Venn overlap of "identify need" "design it" "build it", "improve it". If they are good at that, they tend to suck at letting other people have autonomy though, and they usually also suck at running the office. The rare guy who is good at inventing a thing, making it, and marketing it, but lets someone else be good at ordering supplies and accounting, / customer support is the guy who has a good live.
***** Where is your video, showing your genius at work?
GunFun ZS exactly.. lots of engineers will "Design" a tool to work but lack any fabrication skills.. I fab the "odd" tools i need for work.. easier than sourcing them and quicker for the most part...
Awesome teardown never seen anything like that. "We going to have to 1/2 ass it because the 1/4 ass an't working" best quote I've heard all week. Thanks man, and well done.
Yeah, I was surprised he was using Imperial units for that measurement, too!
It was even funnier when that didn't work either and then had to try the standard way
You know if you paint it flat black with some nice neon green flames you'll get another 2,500~ torque out of it.
naw at least another 5000
Give her a small speaker to play a sound bite saying “click” to achieve proper torque.
Nah...chrome it and you'll pick up 5,000 ez
Yeah, and red ones go faster, blue ones are good luck and yellow ones have a higher explosive yield and if you'll know what I am talking about you win a million points

Funniest thing I have heard this year I think. I laughed for 5min!
I wouldn't b able to get nothing done working with him.. I'd b laughing to much
You and me both!
"Ça fit comme le gant d'O.J Simpson!" :D lol
This thing needs to be installed in the Juicero *immediately!*
Hey, I work in the factory that makes these! Never thought I would see one here.
Ryan Kane Well tell us how it works
I would like to know all the various applications this would hold in the industry.
Man. I study engineering but i am impressed with your handy skills. there are things you do not learn looking into books. love your channel and your attitude
Interesting point on the safety issue. I've had to produce my electrical licence several times but I've never seen anyone working on hydraulics asked for their millwright's ticket.
Good video at any rate!
Im from the Seattle area and assembled a bunch of theses back in the day. Great company and amazing product
Air and any fluid can kill. We had 3 Contractor Plumbers killed in mid 90s, while putting in a 16" water meter. They did not bleed air slowly. It was a 16" 150 psi water main, but it was coming off a 72" transmission main. And they were in vault because north of Detroit it gets cold. Pay attention to his safety advice.
Stephen Paraski
I do find it a bit odd that most people seem to think that static hydraulic pressure is somehow more dangerous than air though. I've probably burst over a hundred tubes and cylinders between 1500 and 12000psi and its more of a cumshot than an explosion due to incompressability. 3000psi air or even 300 though can easily kill.
They were 9' underground with 2-36" manholes as acess to a 10'x18' vault. When the hammer broke that 16" line the volume of water negated any chance of escaping. They did not have any "Retreval Device", after which became mandatory for entrance but are useless as line becomes entangled in enviroment.

Good to see NFG means the same this side of the pond
Not Fkin Good?
@@thombaz Yep
Not fit for grade.
NFG? Not Functioning Generally.
I learned that as an apprentice from an old guy who told me to get my mind out of the gutter!! Didn’t do me much good. Just sayin!!!!
No Fvcks Given
Pretty sure after spending 4 hours of my life watching you Chooch along then seeing this BEAUT; I've become a believer. Constantly blown away by how friggin' knowledgeable you are and catching all the quips is funny as all hell. You've earned another Patron, my friend. Keep on choochin'!
We used these on ships to power the winches (No, not that kind, matey.) for hoisting nets and whatever we needed to retrieve. There were larger radial hydraulic motors as well, high volume, low psi.
That had to be spendy to ship. Looks like it has a lotta gravity in it.
For anyone who has worked on camera lenses, those helicals are bringing up some bad memories!
your fucking awesome dude, you can take anything that would be boring as fuck to watch and make it entertaining, every school in Canada needs a teacher like you
If it's worth tightening, it's definitely worth over-tightening.
Hi guys, OK I'm a chick, and a grandma (albeit a young one) but I weld, and love to take stuff apart & fix, or repurpose, so when I stumbled onto your channel I was a happy girl! Although I am not "classically" trained, and I don't know the names of a lot of stuff, I do understand (I think for some of us it is instinct, my family calls me MacGyver) I wanted to comment on how this piece looks a bit like what I took out of my old washing machine, not the 3 parts, but 2:-) SO anyway, thanks again!
The ask you should be questioning yourself.
Love it!
I gotta say man one of the things I enjoy about your videos is that we never know exactly what you're going to upload. I love all things mechanical and electronic, awesome channel.
I am a diesel and hydraulic mechanic and we work on JLG man lifts and the basket rotator is damn near identical to the one your working on. They are a pain to rebuild and they usually start leaking around the seams from all the dirt and trash around it.its cool to see some one else with one doing the same.
Yeah, I was translating an MSDS for aircraft hydraulic fluid (which I think is about the only time anyone reads the damn thing) and the horrors I had to translate into my native language about hydraulic injection and high pressure systems potential to maim, the effects of the hydraulic oil on skin, eyes and your health in general... Geeez
I was thinking about that when he got the oil on his hands.
Hydraulic injection! For me that's the most frightening part of hydraulic systems. A friend of my father's ran his finger down a backhoe line that was leaking, pinhole shot it down his middle finger into the palm. Had to have half the hand cut out because of necrotic tissue.
I lost it at 11:53 "Ça fit comme le gant d'OJ Simpson" LOL
thereby increasing the chooch factor to the necessary point five
There are good odds that I'd pay for your voice in GPS-Navigation form.
That should make a Hell of a Lemon squeezer.

I have to replace a L30-17K at work (from a Sellick forklift steering). My boss asked if I could rebuild it, told him I'd rather replace it this time then I'll try to rebuild the old one when its not time sensitive.
I'm quite glad i'm not the only one that smacks things with the nearest implement of bashing if they ain't moving and they should :'D
(This applies to everything)
I really like the way you mention how things can go wrong, cause nobody can think of everything, keep the vids coming.
Fuking hell man, I cannot wrap my head around the functioning of that device.
Also, "Release the schmoo!" should get it's own T-shirt.
Jaroslav Malec The larger helical gearset moves up and down inside the cylinder, engaging with the stator gearset on the outer casing, that forces it to rotate as it moves upward. Inside that, that smaller shaft's gearset engages with the inner teeth on the larger gearset, causing it to rotate.
Basically, imagine a hydraulic cylinder pushing on a rack that rotates a pinion and you've got the basic idea. It's a pretty efficient and compact way to translate linear motion into rotational motion.
Teth47 Right, so it cannot rotate indefinitely, it has limits.
Jaroslav Malec Yes, One full rotation if I were to guess.
***** Woot! I've got the explanation of its operation right as well, correct? I didn't look it up, because I like to play it fast and loose
@@Teth47 Agreed. It's really just a gear set that's built in a concentric or coaxial manner rather than side-by-side. At least that's how I'm seeing it.

Even as a 2004 International Fluid Power Society Certified Fluid Power Hydraulic Specialist I have never even seen one of these, Thank you!! I know you use funny terms frequently but instead of Sticktivity the reality is often stranger than fiction, the term is 'Stiction'. Thanks for the awesome entertaining videos.
Hey! Thank you! The PSA on not screwing with high pressure that doesn't make sense is priceless!
The Best / Easiest to use, thread sealant i've found!
LOCTITE 545 (High Temp)
LOCTITE 565 (Fast Cure)
I like it because it allows you to clock your fittings however you want/need cause its sets up where you leave it. No more adding or removing tape to get the fitting not to leak and pointed in the direction you want!
P.S. I also hate pipe dope...
I resealed one of those. We called it a tilt-a-whirl. It was for an articulated bucket on an excavator. Ancient John Deere backhoes used them for the swing before using regular cylinders. Good video.
It didn't occur to me until today. I work with a smaller version of this on a fairly regular basis depending on the truck I'm driving. The regular piston type hydraulics used to do the same job as this one break a lot more frequently and are more sensitive to abuse. These rotary types are damn near bulletproof. Nice to see how they work turning linear motion into rotation. Sweet.
These are bombproof because all moving parts are contained inside the cylinder. Linear rams extend and retract, and that is what makes them less robust.
This is the most informative channel ever, from funny quotes to drama and action in a single episode.👍🏻
Noticed that you use a Crescent Hammer quite frequently. :)
I live in the small town where this magnificent beast was made! I actually know one of the engineers who designs them.
This comment gets no love?
Come on!
Either ask this guy some questions or call him a fraud but don't ignore him
Love the grass growing out of the top.
Thanks
John
You've acquired yourself a new subscriber, sir. Thank you for sharing that with us. I have messed with these before and understood the concept just fine. However seeing inside of it was amazing and enlightening. You gave me that, "Ahhhhhhhh." moment and I thank you.
"10,000 PSI in the wrong spot will turn you into... dead."
HAHAHA
"release the schmooo .... yaaaay"
Mind blown. Absolutely love those gears.
I learn new things every time I watch a video ! Love the one liners !!!
Give or take 10% he says.....LMFAO
Helloooooooo binge watching some AvE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I can provide a solid argument to that with money, Ferraris and scantily clad busty blondes....back to my binge watching!!
+Chris Buccos bud i fucking love this guy, how hes got any dislikes is beyond me
Just haters doing what they do LOL
same reason that liberalism is a mental disorder is same reason that anyone would dislike this video...not even worth your time wondering why just know they are lost already
@will pugh - Certainty bothers people. He knows what he's talking about and that makes people who THINK they know, mad.
Soooo, what does "NFG" stand for? No Fucking Good?
You guessed it
In late but it meant non functioning
This guy's turns of phrase are phenomenal.
This was such a cool piece of gear! ⚙️ i love that the repair was so simple. Would love to see you use this on a project
that BLEW MY FUCKING MIND!!!
Awesome!! Never seen one of those before. What's it primary use? Is it linear and rotary at same time when pressurized?
Always gotta love your one liners man. Enjoyed!!
Adam
Rotary only Adam, we make them where I work. They are used on excavator mounts or garbage trucks that pick up wheelie bins. Can also be used where space is limited to use a traditional cylinder
banana5616 Thanks. I was guessing something like a tool holder on the end of an arm that only needs to rotate so many degrees and then return.
***** "banana..." said it was used on dumpster trucks and excavators. Any idea what they used it for on excavators? the best guess I could make was to drive the thumb on a compact excavator. They have little ones that will even fit on pickup trucks, for getting into tight spaces without smashing stuff up. It could work for that kind of application.
GunFun ZS We have a back hoe at work with a clam shell digging bucket it has 2 of these on it to open and close it . Its useful for picking up pieces of debris to put in the dump truck.
fatboyfester Here is a photo of the type it is www.bing.com/images/search?q=clam+shell+backhoe+bucket&view=detailv2&&&id=30CE37115F1B96A21A8883A9C3709D3C6FDFF52C&selectedIndex=96&
Man, i am a contractor and a half ass home shop maker. My guilty pleasure is buying tools and equipment i dont need for work... so i am always looking at tool and equipment review sights and while looking at something function before buying is ok, of coarse am always disappointed at the constant overt pandering to the source of the free equipment by reviewer.
I stumbled on a few of these vids 3 months ago and have become completely addicted. This guy knows the real deal on everything, and though the occasional relevant tool review & teardown got me subscribed, the brilliant lessons in real world mechanics, equipment manufacturing & design has literally turned this into my houses most watched form of media, bar nothing. My 10 yr old son and i have actually found words like skoocom in our father son vocab, as well as now using the occasional thickly accented Canadian slang phrase when we run into generally preventable fuckery in something that should be better done,
Thanks for what is obviously a huge effort put into actual dynamite content!
"You need to be super careful around these types of pressures - they can kill you dead." **Proceeds to beat on everything with a wrench**

And I subscribed. ..!!!!!
AvE, being the electronic guy i am, i TOTALLY popped a monster chubby over this machining masterpiece. Thanks loads for showing it off!
Worked at helac in Enumclaw Wa. for a year, great company! Most commonly seen use of this kind of part is the basket twisty bit on a giraffe style man lift what makes the basket go left and right without moving the body. More of a neck shake than a twist of her hips! On a much larger scale, it's older more robustly devastating brother is mounted on the backhoe bucket of an excavator and allows the bucket to dig left or right instead of just back to front. Only the lady's should be using the back to front technique! SKOOKUM AS FRIG! We built them that way. MURICA!
Greatest video of all time. I work on forklifts for a living and this guy a freaking hydraulic comedian. This is great. Really cool actuator too. Just great. So happy I found this video.
"She's got a little gravity in'er."
I once asked a guy if something was heavy. His response was, "It's all there." Now I have two funny ways to say something is heavy.
turns linear motion into rotary motion. a piston moves in one direction with a spiral gear on the end, and engauges another spiral gear. piston moves, the end turns, piston moves back, then end turns the other way. simple.
Not gears , they're multi star acme threads.
These are pretty sweet actuators because they integrate both rotary actuation and a pivot shaft (as it runs on two tapered roller bearings) unlike most motors which are only good for powering another piece (thick of a motor and a slewing bearing. I have used these in a foot-mounted configuration on a few different designs of underground mining equipment (I'm a design engineer).
I know that I am late to the party.....frickin amazing brother. I’ve seen one of those contraptions many many moons ago. All I remember about it was some clip board goon was yappin about how important it was for the filtration of the fluid to be monitored very closely. That brought back memories
What does BOLTR stand for? Live this unique hydraulic rotary thing!
John Resciniti Bored of Lame Tool Reviews?
Thank you! Duh on my end!
Son of a diddly!!! Well that was a let down.
Gotta be a beatch to bleed that if you do not have it prefilled during fixing, getting that last bit of air out so it will not hop around if the fittings are below the piston will be a lot of cycles. Even simple linear actuators mutter about that, especially if you want to have a repeatable step with varying loading or are using feedback.. At least the bar tending robot will be able to serve a drink even if there is an inconvenient body in the way of it slewing, though said body might be somewhat inconvenienced by the motion.
I lost it at 13:39 - 14:02 it was the absolute perfect summary of every tool and tech tear down in my life. Looking cool, calm, and collected while taking it apart to "fix" 'er, but in my head...
I love the friggin variety of tech stuff, machines, hydros, electronics ect..Love this channel. This is so much more intersting than the "Reality" shows on cable...TV's dead long live "AvE"!!
Oh, man. Yes, tell me. I was set to work on a hydraulic system that had NPT 1/2" fitting in and among the assembly. The hydraulic pump had to be rebuilt. But I was putting the hammer down until I found that little nugget. Yea, nugget of el crapola. Could have sliced me clean into multiple pieces, I know you know what I mean. It was a ten thousand pound test on cast/machined fuel pump housings. Production line. I had zero drawings, nothing. Just cold death waiting for me. I should have run screaming from that place the moment I reported for duty. Long story short. That machine I fixed and brought up to "code." What nailed me down the road; a machine with no drawings, cycled on me while I had a screwdriver and my hand/fingers. Flywheel system released, shattered the screwdriver, shot metal up into my face, thru my upper lip, along my teeth and skull bones and stopped just under my left eye. Also broke my right index finger into seven pieces. Was a little story of caution for you. They were pissed that I had to go to the emergency room, but bled all over the shop before I was taken to the Doc. Some people. Heh? My wife about spewed and fainted when they brought me home.
NFG? No Fucking Good?
Aaron16 Officially Not For Go. Or at least that's what you tell anyone who looks offended when they ask.
Thats how they write "Does Not Chooch" in Azerbaijani.
This term is used in on set film/tv production as well. Some people use the sanitized "NG" version
Aaron16 Very close to "FNG".
Aaron16 "Not Found Good" ?
Hilarious! Great fun and super interesting. I hope your viewers appreciate how much good advice you give them! I've taken apart lots and lots of stuff but never seen one of them! I will subscribe!
I am glad I found this video again, I am about to rebuild 2 basket rotators at work. Seals kit is about $100-200 and a new rotator is over $1g. To put it lightly, my bosses are stocked that these can be rebuilt.
So, am I right when I say this thing cant turn endlessly because the linear motion inside is limited? Otherwise I dont get it...
1hdsquad Maybe it would just be used as a short throw high torque actuator. To move something on/off that is very hard to turn.
***** are you sure? because i figured that since there are two gear meshes this thing might turn continuosly but that the piston will do some linear movement, maybe proportional to the output torque, or to help it get up to speed? anyway, if you know more about it i'd really like to hear it
+1hdsquad It rotates 360 degrees
31,000 ft/lbs of torque! That's pretty massive. Yep, hydraulic actuators are only limited by the crankshaft that drives the pump and the amount of pressure that the lines can handle. They use hydraulic pressure to test air compressor tanks, scuba tanks, etc. If the tank fails/pops it only cracks open, no explosion.
WAVETUBE84 The you're looking for (or more likely, already know), is hydro-testing. They use water not hydraulic oil.
prairie wanderer I used the word "hydraulic" : that means any fluid. Yes, they do not use petroleum oil for testing those tanks. Water is what is used and it works perfectly. Plus no need to use additional petroleum solvents to clean the tank. Just blow it dry with some warm air. And any petroleum vapor mixed with oxygen/atmosphere and pressurized in an enclosed container past 234PSI will EXPLODE!!!!!!!! Diesel engine ring a bell.
WAVETUBE84
I was pretty certain from reading your post you knew all about it. My words were for the benefit of those less-informed. I've heard a story or two of someone lubricating the threads on an O2 cylinder before mounting the regulator. Not a happy outcome.
prairie wanderer Put a drop of oil on a tiny (.177") cotton wad. Put that into a pellet rifle, after a pellet, and see what happens. Poof, bang, crack! Nothing dangerous, but you will have a small diesel detonation. Don't know if you get any additional velocity out it though.
WAVETUBE84
I might have to try that later. Might also have to try some rudimentary penetration tests to see if it boosts the velocity.
You make me so happy with your mannerisms. My new favorite youtube engineer.

***** Very interesting: Here is a huge difference between our channels. Though Americans are my largest audience they only comprise 21% of the total viewership. India, Germany, The UK, Australia and Canada combined make up another 30 percent. The rest of it is very equally spread over the entire globe.

BANANA FOR SCALE! hi from imgur!!!
I've done these spinny cylinder things. On JLG lifty things. Pretty simple as long as u get it back together right or else it kinda turns too much to one side and not enough on the other. LOVE THE SHOW!
Their amazing pieces of work. We use them at work on our drills to replace cylinders. Ours are quite a bit bigger though
This is the coolest fucking channel on YT. I've learned so much in the few weeks I've just been binging this stuff on my downtime. I hope you keep at it, Sir.

We make these at my work they are used on excavator mounts or garbage trucks that pick up wheelie bins. Can also be an advantage where space is limited for mounting a traditional cylinder
