I did my teacher the grand favour of showing him this video about 10-11 yrs ago and totally made his job so much easier that day x)

I have a 1965 Belair, the service manual from Chevrolet says diff oil life. Life of the vehicle. There was no specified interval in miles or time to change the diff oil. Oh and yes I have changed it, I bought it 35 years ago.

Anyone here in 2025????

Differentials have been difficult for me to grasp without having one in my hands. This video changed all that. Seeing the concept with the two and four spokes finally made it sink in. Brilliant.

Pretty good until about 7:20. Then, the narrative seems to (pun intended) shift gears and goes on about the advantages of a lower driveshaft or some such thing. Another minute on the actual workings of the differential would have been much, much better.

Good thing we used to have brains

ขอบคุณคับ

是不是純電動車看有沒排氣管

Bruh still had two more gears left thats wild

Hi I'm watching this year

i realy love how they explain it

thats a great tutorial

시벌...영어를 못알아들아도 이해할 수 있는 영상

Now i know how it works.

true legends those guys... i can only envy them

Who up jamming they handy rn

Amazing how the principle and concept are explained in a gradual fashion, from a very simple design to a real and complicated one. When it comes to teaching, knowing is the first step. However, how to teach is a whole new field of expertise. And this short video excels in that.

I always wanted to understand how a differential worked, but I never found a simple explanation. Now, thanks to this excellent tutorial, I do.

Great video

Amazing explanation! Ultimately intuitive.

humans are amazing

Where can I find more of these videos on car stuff?

This video learns one more thing: split big problem into easily solvable steps.

I’m an engineer and we don’t innovate like we used to. Nowadays is all about getting promoted and job hopping every two years

Genius

best soundtrack ever

more spokes

It's the ability of the spoke at the top of the arm to be able to rotate, which is the key characteristic of this mechanism. I think... The 6 minute mark

One of the best videos I ever saw

Holy 😳

Locking differential makes much more sense now. In order for an off-roader to make it out situations it locks the diffs so both wheels are spinning at the same time instead just one freely spinning. I’ve been explained this before but never got the reason why.

Question when you installed your bov on that side how did you set up your vacuum lines because im currently doing mine on my 2013 bk2 and this is the only thing im stuck on bc of confusion and every example of the bov being on the throttle side is a bk1 so just askin

I think this was the best explanation of differentials I have ever seen.

I say this as a mechanical engineer, but I swear the engineers of the olden days were the smartest

Awesome! Very nice explanation!

Genius ❤

whoever design this gear back in the day is truly Genius!

Didn't get it

from gpt4: The tutorial you're watching, if it's the famous video that's often shared online, was likely made by General Motors Corporation (GM) for the New York World's Fair, which took place in 1939 and 1940. The purpose of the video is to explain the mechanics of the differential gear in automobiles in a simple and understandable way. Differential gears are a critical component of all modern cars. They allow the wheels of a car to spin at different speeds, which is necessary when the car turns. During a turn, the wheel on the outside of the turn needs to spin faster than the wheel on the inside, because it has a greater distance to travel in the same amount of time. The differential is the device that splits the engine torque two ways, allowing each output to spin at a different speed. The video was a part of GM's effort to educate the public about how cars work. The more a person understands about their vehicle, the more likely they are to maintain it properly, appreciate its value, and potentially invest in higher quality vehicles. It's a form of content marketing that many companies still use today. The film you're referring to, known as "Around the Corner," was produced by the Jam Handy Organization, a pioneer in industrial films and visual education. This group was led by Henry Jamison "Jam" Handy, an Olympic athlete and successful entrepreneur who used his company to create thousands of educational and promotional films over several decades, many of which were for General Motors. "Jam Handy" wasn't a division of General Motors but was a separate entity that worked closely with GM (and other companies) to produce these kinds of films. The "Around the Corner" film, specifically explaining the differential gear, was created in 1937. General Motors and Jam Handy had a long relationship. Handy's company produced training films for GM's employees, promotional films for potential customers, and instructional films for the general public. These films covered a range of topics, from the mechanics of different car parts (like the differential gear) to the virtues of capitalism and the free market. These films were part of a broader movement in the early 20th century to use film as a means of education and propaganda. With the growth of car ownership during this period, there was a need to educate the public about how cars worked, both to help them maintain their vehicles and to make them feel more comfortable with this new technology. "Around the Corner" and films like it played a key role in this educational effort.

I love these.

Теперь я понял, как оно там работает .

infinitely better explained that most of the crap I learned in a top 10 engineering college.

The working principle of differential gear is cool. As the variable compression crankshaft.

Absolutely the best demonstration of how/why a limited-slip differential DOESN'T work when you need it. Remember all of those times when ONE wheel would spin (the one on ice, in mud or loose sand, or left hanging high over a pothole) while the one with traction does nothing? Yeah, this is why.

Thank you!!

After 45 years I find a really good explanation of a differential 👏👏👏👏👏

SUPERB vid

진짜 요즘 만든것 보다 직관적이고 설명도 자세하고 원리도 알려주고 작은모델부터 실제모델까지 인과관계에 의해 설명해 주니 이해가 빠릅니다

Gue di mana coookk Gue dri tahun 2023 😅

So, THAT's how a differential works ! A 90 year old training video that puts modern stuff to shame. I wonder where the incentive came from to produce it. It is very high quality and well edited with it's animations, but at whom was it aimed ? Ordinary car drivers, schools, mechanics ?
