the first time i learnt how a differential works was from a video made in the 1950s, now i know how power steering works. these videos are awesome
1wsx10 I couldn't agree with you more. :D
Exactly
+1wsx10 they are so well made!!!!
+1wsx10 these are the basics to the old systems. Modern systems are a lot more complex.
Y10Q
fuck.. really? i thought todays technology was so much more efficient because of the auras
Everyone says how clear and simple these videos are, you have to remember recording equipment was very expensive, film was expensive, all the drawings are done by hand so you had to pay attention to everything to the point where you had to be very good at what you were doing, and when you are that good, it usually means you have learned to break up problems into their components and are able to think about them / present them accordingly. This is the gold standard right here
One of these videos showing how a differential worked was brilliant in its simplicity. The only complaint I have about this video, and admittedly it is a petty one, is that when they are talking about a pressure differential they actually mean a pressure difference.
Today this would be done by using CAD instead. Those are essentially free to produce but it takes a lot of time and effort to design and sometimes animate the components.
very good point
Excellently put.
Agreed, explaining an advanced concept in a simple, easy to understand way is much more difficult than just understanding said concept.
I'm glad the people who invented things like this were so proud of their inventions that they wished to share it with the world.
Prob military training vids. I was in the Marines in 81, motor transport. This film, and the trucks in it, look " very familiar".😂
When cable tv first became popular back in the early 80s channels like Discovery and Learning Channel (TLC) had shows like this. How refrigerators worked. How clocks worked. I was fascinated by these programs. But for some reason they're all gone now. Replaced by some of the stupidest programming imaginable.
Which is why I dumped cable tv and went back to an antenna on the roof. Thank God for TH-cam!
molson12oz grow a Jinggler and figure it out quit bitching
TH-cam has replaced Chilton and Clymer manuals! And yes, HGTV, discovery channels are dumbed wayyyyyyyy down. It's a shame.
WTF man? You don't like american pickers and ancient aliens?
Closest you'll get now is How Its Made
A good teacher is one who can take a complex subject and make it look simple and orderly to students who have never been previously exposed to the subject.
***** Grow up.

***** who are you calling a fool? John Fraser, Abdy Leibrook or Albert Einstein?
***** i did not say anything though
You're a stupid fuck Adam.
And all of this great explanation and illustration before any CGI, or fancy filming techniques. All done by hand with film, and it is so amazingly clear.
+morsteen
Everything can be presented clearly if you really understand it. We have so many engineers and technicians today that never leave their desk. And it starts to show.
Strangely the average understanding of mechanical systems goes down in western countries. I guess we are not producing much anymore, so the know how follows the factories to Asia.
Not judging here, just an observation.
And a very good observation too!!!
morsteen Not to mention that instructional videos nowadays have such loud NOISE, called (music) that makes it hard to understand what the narrator is saying.
Noise...music? Yes, it seems Americans are addicted to 'stimulation'.....
True, but complexity of systems has increased as well, to the point where simple explanations are difficult to make.
As I watch this, my 6 year old son comes up and starts watching over my shoulder, so I scoot over and make him some room and we are both watching. So awesome something like this can be so engaging and informative and be from the mid 50s. I've learned more of the basics from old material like this than any other modern references, and apparently so does my 6 year old son.
I wish we could move back in time to get some decent teachers and profs from the 1950s....
"Decent teacher" that takes 15min to explain an stupid hydraulic steering. If you need a 15min video to understand what normal people would with just an schematic picture, it's because you are stupid.
Then why did YOU watch the video?
....? Normal, I.E. Average people have absolutely no idea how this works. A "normal" person doesn't just look at a schematic without explanations and go "Oh, that's how this 22 part item functions." If that's how shit worked, teachers wouldn't have ever been a thing.
+Anderson
It's all about presentation. This video is an excellent step-by-step visualization of the process. It's one of the best learning tools that there is.
That's why the military uses it.
Luckily, through the power of film video, and internet, we (kinda) can (go back, etc).
I wish manufacturers still made videos like this
+Matt Vega the chinese don't allow that
did the manufacturer make it? if it was the manufacturer then it appears to have been funded by a military(many of these old videos appear to have been intended for military training)
@David Ortiz Death to china
*These instructional films were carefully thought out and well scripted. TH-cam Instructional Videos by amateurs are the worst in digital history. They do not speak well English, speak too fast, not articulate enough, have poor graphic skills. etc.*
@@leegenix and they destroy them with disgusting musuc!
FFS...why can't they make vids like these anymore? Now all I see is some guy ranting about why their product is better than the competitors by neither saying how his product or their competitors work!
Corporations want to keep their design a secret because of competition. This was a patented system so there's no need to keep it a secret. I'm pretty sure the patent has expired by now though.
@@PunakiviAddikti That patent was already expired when this film was made back in 56
I found a channel that goes over the basic components of a smartphone or modern electronic kinds of videos like this one but made in modern times
There are actually many "explanation" videos like these made over the years, but it didn't have the conciseness and genuine vintage feel which i preferred.
It's Idiocracy man
These old films are pure gold. No advertising, no bullshit, just facts.
Nothing like a rousing march tune to get ya ready for a lesson on power steering...
Oilsmoke Jones hahahahahahahaha....a rousing regimental march before cold showers & a sound spanking from matron....oh....no hold on - I was thinking of my school-days...!!!
Hahahahaha that’s crazy true 😂😂😂😂😂
I was so excited!
Sometimes I want to put a unlit cigar in my mouth and chew on it a bit before lighting up for one of these - until i remember I don"t smoke. Other times I want to drive my Granddad's 61 Eldorado Biarritz Convertible and enjoy driving some Detroit American steel.
Its a Mexican march, Zacatecas, composed by Genero Codina.
To anyone wondering why such an old video seems so much better than modern instructions, consider the survivor bias at work here. The old instructional videos that were confusing or poorly done were quickly forgotten about, while videos like this are so good they hold up to this day.
Good point.
Ahhhhhh, like all the mst3k shorts? Mr. B Sharp didn't teach me anything!
Not that I don't agree but to prove this point you need to show us a modern alternative to this video which is as good as this.(well this one wasn't as good as the differential video. |-OPTIONAL- try finding an alternative as good as that|)
Burak Baggins engineeringexplained is a fair comparison. used to be atleast havent watched in awhile
He has a point. The video that came with my D-43 Swedish Suck Machine was the nuts. Every detail laid out in clear detail again and again.
Training films like this one are absolute gold. While I'm certain that this particular system has been improved over the years, some of the components are still exactly as shown. I now understand steering far better than I ever did. Thanks for sharing this with us!
These videos are freaking great! I had my dad and grandpa to teach me all this stuff but I am so glad this is available for people less fortunate.
Help I'm stuck in an endless loop of watching these old programs about automobiles even though I know how everything works already
@SMTFITNESS not quite EVERYTHING but I know enough to where if anything breaks I can fix it fairly easily
@SMTFITNESS saying everything was a bit of an exaggeration
This amazing video was made in 1956, and Brazil still makes some cars without this technology...
It's not like they don't know about it. It's like Ford not making every single one of their cars electric. They don't do that becuase that would make the car less reliable and more expensive.
I'm certain that the car you are talking about is very cheap to buy. To reduce cost, manufacturers need to find places where to cut expenses. They thought hydraulic steering wasn't vital. And you can still drive a car without it, it's just a bit tougher. May I know the car you were talking about?
What is better a Brasilian car or a 60 year old car?
depends on the brazilian and the 60 year old car, my mom has a 72 volkswagen beetle and that car is just wonderfull, 3,35 millions volkwagen beetle were made just in brazil, the isnt such thing as brazilian car, there is not that much national manufacters
você tem ideia do valor que um brasileiro que recebe um salario minimo ganha por mês? são menos de 300 dólares, se não cortar custo de produção, as classes mais baixas são condenadas a serem levadas para a cova de ônibus
Esse é o modo totalmente errado de enxergar, o americano "pobre" anda de Corolla 0KM, aqui ele é chamado de "sedã médio" e custa mais de 90k, já nos EUA custa menos de 20k (e não faça a "conversão burra", americano recebe em dólar e compra em dólar, brasileiro recebe em real, e compra em real, não tem que converter nada)
Aqui o brasileiro burro compra caro porque quer mostrar pros outros o seu "poder aquisitivo", já no mercado mais amadurecido como o americano, se o produto tem um preço alto, o consumidor simplesmente não compra e o produto sai do mercado ou baixa o preço , simples assim.
Não existe essa "justiça social" que você propôs no seu comentário, somos explorados porque somos burros.
I love how clear and concise these informational films are. Such a valuable resource! I remember seeing similar films back in my school days, and they really aid in understanding the concepts behind the systems. These were made at a time when manufacturers wanted the consumer to know how their own vehicle worked. It's interesting to look at owners manuals from decades ago and see just how much useful information was in there, unlike today where most of them just say "See your dealer" for anything.
Back when a lady might have to jiggle a stuck choke to get it open, I feel like everyone back in this time had to know a little bit about machinery or you'd be left behind.
Films like this were shown to high school students taking shop courses back in the 60's. Sadly, many schools eliminated shop, or industrial arts as it's sometimes called, because they thought all students should go to college and study computers. Now I love computers, and my ability to understand them partially stems from having taken electrical shop in high school in my senior year. I also studied science, history, math and art as well, but my favorite subject was wood shop! I also took mechanical drawing for a month before the school cancelled the class due to there only being five students. The school also cancelled the auto shop course after my first year, because they needed the space to park buses in winter. Total shame!
if they changed the name of the course from Shop class to Life Hacks, kids would sign up in droves.
*I too, liked these videos in school. The only course I hated was Metal Shop because the teacher was a jerk. I loved Mechanical Drawing and Electronics. The teacher was also my boss when I worked in his shop after I graduated. He also gave me his old US Navy books.*
no.. many schools didnt "eliminate shop" lmfao. hundreds of thousands of trade schools in canada
I had shop and auto in school too. They are by far the most expensive classes for the schools so the easiest to do away with. Our auto shop rivaled any actual automobile repair shop I've ever seen. It was huge and had six lifts, big tool carts and a big tool room full of everything you'd ever need. All the carts and tools were Snap-on too, I can't imagine how much it must have costed to make and stock that shop with everything. I remember I was fifteen and had gotten my first car when I took that class and thinking that it should be a requirement for all car owners because of the invaluable information and skills I learned.
I remember watching these kind of videos while in the navy.. the teacher was always watching who was sleeping during the video. when someone was caught napping, we would all have to run a mile or two around the base!!! trust me, you don't want to be the guy who was caught sleeping!----lol
But videos like these are so interesting. The sleepyheads deserve the run.
Just like in Soviet Army :)
millennials be out here watching this for fun.
if you sleep watching this a mile probably isn’t enough
Alot of respect for the engineers/science to design working, reliable, cost effective system during any era and to build upon prior knowlege with innovation.
"A lot" not "Alot". "Alot" is a town in India. Or are you talking about engineers in India?
this youtube channel has officially teached me more about cars than mechanic school. great stuff!
I work in garage and it always was a mystery box for me. If doesn't work- replace.
This design is simply genius. A completely mechanical powered steering assist which only requires the engine to run in order to function.
This old videos explain better than newer ones.
1950s, when cheap things were of better quality than expensive things today. Good old days, and I'm from the 80s.
1950’s you were lucky if a Detroit junker didn’t rust out from under you in under 10 years! I’m 69, and remember how bad those cars were built. Never drive a domestic piece of crap again!
Notice the timing. Information is presented in a logical sequence, slowly, clearly, goving it time to sink in. Brilliant.
Very true, Rick. Many youtube-ers seem to speak as rapidly as possible with little regard for timing and the fact that the viewer must assimilate the information. IMO, the first rule of teaching is . . . slow down!
These videos are so good that we watched every single one of these old videos when I was in trade school for heavy equipment tech
im in school to get my degree in wind energy technology and these videos are really help full. We are studying gearboxes (with planetary gear reduction) ac generators, and hydraulic pitching and braking systems. thanks for the posts!!!
In the 1960's and 70's my father would bring home films like this and would play them on our projector. Sometimes the film would break and he taught us how to splice it. Several companies had large libraries of these films, mostly to be shown in schools. When Daddy cranked up the projector, it was a treat for all the kids.
When I got to college, physics was a breeze!
When video games came out, they seemed brainless. "Thank You Daddy!"
Absolute genius that came up with this, I tell you.
These old videos are better than the ones today
@Raul mechanics was he the narrarator and designer of these documentary's?
I love these old videos! So informative showing how complex yet simple things used to be. Thank You for sharing these.
I enjoy this kind of simple videos
Yep.. me too. Matter of fact.. I wish I could wake up tomorrow.. and 90% of this bullshit modern technology would be gone! Starting with *_TEXTING_*
And TH-cam. :D
Blaze0357 yet here you are on TH-cam, through a computer, connected to the internet
Such pride was taken with these great information films. Thank you.
Was a master ato tech for two decades and love seeing training films like this
They got to the point and in a very understandable manner. Loved how he put it all together.
Reservoir, pump, control valve, releif valve and jack these are the basic components for Hydraulic System. Thankyou for your valuable video.
Something about these videos make it so easy to understand.
Thanks for this. I wondered how this system works and now I know. These old films were very descriptive and well produced. It's all very clever and must have taken a long time to get to production.
I always wonder how power steering works. These old videos are amazing
At the beggining, the music is La Marcha de Zacatecas, Salute from México. :D
I finally now understand the valving behind power steering. THANKS!!
Very Clear teaching of technology we take for granted! digging the March of Zacatecas too!
I had a notebook to note upcoming shows like this day&time when their trailer passes during ads, This brings back memories of my little brain fixing the tv when discovery & national geo had stuff like this... My dad would watch with me answering my hundreds questions ohh and warn the one who try to change channel or don't put my shows when it air.. you could hear my cry for miles 😩
I never understood power assist steering, let alone the theory of bump steer until I watched this film. Good ol 50's era educational Army films.
I love these old videos, way better than any modern CGI stuff beacuse it's explained clear and simple
No modern videos can do it like that
I love the simplicity of these videos they are easy to understand
I have been learning huge amounts about basic mechanisms by watching US Army training films, some from as early as the 1930s. I now understand how (this type of) power steering works (in basic) and could repair or build one if needed. Yesterday, I still did not know how the assist and feedback worked. Now I do. THANK YOU.
These old school instructional videos are amazing and do a great job at explaining things. I've replaced these systems in cars and even large diesel engines without really understanding "how" they functioned. It's one thing to understand that part A does job A, and if you have X symptom, then part A just needs to be replaced, but it's another thing entirely to really understand exactly how part A functions at a component level.
Power steering (steam and mechanical systems) were available on the big steam powered plowing tractors of the early 1900's. All wheel drive was developed earlier, about 1885 on these same machines.
As I'm currently working for TRW helping make steering parts, you might be surprised how similar the modern resembles this film.
That's awesome, I have a TRW electronic module that was hidden inside the dash of my motorhome, I can't figure out what the hell it is or what it does, so that's how I came to know the company TRW which is apparently one of the biggest manufacturing companies for car parts now, never knew this
Pausing in the voice explanation is wonderfully paced
great video..thanks for sharing
Excelent .principles of explanation thx.
the control valve is the brain. the pump is the heart. the power cylinder is the muscle. the reservoir is the bone marrow.
Nice anatomical comparison
One of the clearest videos of the internet.
Remember hydraulic steering is not the same as power steering. The are very few passenger vehicles built with hydraulic steering, this is usually reserved for very heavy duty trucks. In the US hydraulic steering is not allowed on passenger vehicles.
Just great...now I have to find a 1950s video explaining the difference between the two.
What are you talking about? Up until a few years ago almost all US passenger cars were equipped with "hydraulic power steering" which has a pump, a hydraulic oil, and is roughly comparable to this system. Maybe you're confusing hydraulic power brakes which is normally only seen on large trucks, whereas cars use vacuum power brakes. My dad has a GMC 2500HD pickup and it for example uses hydraulic power brakes
My dad joined the Army in 1961 and was trained as a mechanic. I am sure he watched these film strips. He was stationed in France, then Germany before being sent to Vietnam in 1968.
I really admire the kind of thought processes that led to the development of this system. I'd love to see a similar video of modern electric power steering not driven by the engine.
Because of this video , holy cow I think I begin to understand how it works now for power steering thank you Uncle Sam and you good ,Sir or madam .
Brilliant system never knew all that went into it, especially the anti kick back and how it worked
All of this and more included inside the legendary Saginaw power steering gearbox. The "more" was an ingenious design feature that gave the car equipped with one the ability to set front-end alignment such that road crown pull to the right can be almost eliminated and at the same time no noticeable left pull when on flat roads like interstate highways.
This is just TREMENDOUSLY great. Love every bit. However, this is a wonderful example of a video that would be even greater if modern stabilizing and sharpening was applied to it.
Me encanta. Sube más material.Gracias
My 2018 Honda has this exact system! Whats old is new.
2017 is now and i watched 1 of these...amazing
Clever design. I love it.
Beautifully explained. My first and only concern was understanding how the control valve was only activated when needed. Seeing the springs on either side of the cam explained most of that. I wonder for how long the springs engage the control valve after tension is released from the springs. Certainly it’s not immediate.
They really knew how to teach things in a easy to learn and understand way back then while making it entertaining as well
Love these films.
well presented, clear, easy to understand... Thank you
I love how most of our modern car technology is still from the 1950s. I mean it's more fine tuned these days but it's basically the same as back then.
1956 teachers: *I CAN EXPLAIN EVERYTHING CLEARLY SO FUTURE STUDENTS CAN UNDERSTAND*
2021 my lecturer: *i uploamded pdf you can study it's the sayme*
Another great thing about these old films: no annoying music during the explanation.
I feel like I'm in the paradise when I watch this videos
There is some beauty hidden in those old all mechanical cars. Today even steering is controlled via computer.
The people in US were so lucky that they got such a good visual illustration..thats why they understand the subject so well and cracks the interview and get job into good company or owns their workshop or garage.. here in INDIA we struggle to understand the basics with lot’s of effort..only super hard working go on top and rest lives there life like regular middle class people..
For some odd reason I enjoy watching these lol
This is such a good instruction video. Even better than modern methodics 😅👌
Carai truta, finalmente um bom vídeo explicando, vlw pelo conteúdo, saudações do Brasil
I've learned more from 70 yr old vids in black and white than from vids of these days in HD w/ fancy CGI.
That truck is LOVELY.
I don’t know about the rest of our fine TH-cam commentators but I’m about to let loose with a powerful shart.
This is more accurate and easy to understand than a modern powerpoint presentation
I taught college automotives. In the steering and suspension class we'd take these things apart reseal and reuse if possible. We opened shop for student and staff. We only charged 10% (to the big guy lol) over cost of parts. We brought in the money buddy!
And we replaced brushes in starters and alternators in automotive electricity and electronics in class. We rebuilt most engines, and learned not to be parts replacers, but today is cheaper to buy a rebuilt. With no garentee it will work the first time.
simple great videos
Im sorry, but the amount of ingenuity that had to be used to create this in the first place is massive
Amazing content.
this is from back when America was great
mike cubes - OK , whatever you say donny trumpy
America is still great probably better, just liberals trying to bring it down from the inside
joe smoe Hmmmm, I smell someone isn't happy with not being racist
Lol, before we became complacent and let Japan become the largest auto manufacturer.
You mean when we had strong unions and corporations had to pay their taxes?
Que buena suerte tuve de encontrar este canal, como en los buenos años de discovery channel, desde ecuador
La marcha de Zacatecas... Love It!
this series from 50's era is alien technology. Too many great car related inventions. 🙂
this is awesome very nicely explained
i just fininished highschool and i spent some of my time in school going to a career center. we took tests to get student ASEs and multiple questions had pitman arms. pitman arms arent used anymore so i was clueless what or where a pitman arm was. this clarifies that
I enjoy watching these work because it's simple
Nice video about how power steering USED TO WORK.
It's hard to imagine how difficult it was for the engineers to bring this system to a working order, let alone imagine it in the first place.
We've been perfecting it for almost a century, and we've got a great result nowadays.
This is amazing. Power of hydrolic system 💪
What an excellent video
Sometimes simple is just the best way to explain something
