What's Inside an F1 Gearbox (& How it Works) | F1 Engineering
In this video, I open up an F1 gearbox to find out what's inside and explain a little about how it works.
I used to work on race cars many years ago, but it's been a while since I worked on any part of any car, let alone a Formula One car gearbox - as you can probably see in this video.
Anyway, it was a lot of fun to take this apart and see what's inside.
Thanks to Mansell Motorsport for allowing me to take this apart (and for them to put it back together!)

The violent impact each gear shift produces when gears are engaged on such small pieces of metal at such high RPM is unfathomable! Thanks for the vid, it makes me truly appreciate the sophistication of F1 engineering.
My thoughts too. I thought they have synchronizers attached on these
@@MrWarhead16 As you increase the number of dog "teeth" you require less in the way of synchronisation; as this is also a sequential gearbox, the need for synchronisation is reduced. Another method is the piston which moves the gear selection shaft (which in turn moves the drive dogs) has electronics to synchronise the shifting of the dog at just the right time. "Consumer grade" manual H-pattern gearboxes usually have just three drive dogs, hence the need for synchromesh systems and rev matching. Modern sequential gearboxes now engage both the current with the next gear pre-selected. Manual pre-selector gearboxes used to be a thing on old Volvo's (change gear, then push in the clutch, release the clutch, and "bingo" the gear is selected. Fun fact. At Monaco, a Red-Bull engineer was looking at the Super Aguri car when his eyebrows went up and he asked "How in the hell have you got our gearbox?!" (At the time, Red Bull was one of the few teams with seamless shift and the SA gearbox was identical!) Aguri san was not phased at all. He replies "Actually, you have ours." This was technically true. The gearbox run by SA was the first seamless gearbox on the grid when it was originally in an Orange Arrows. SA bought the entire OA equipment and intellectual property. However, the gearbox was also licensed by Red Bull (well the original team did) when OA folded. I loved the access I had in those years.
The first time ever I understand throughly how gearbox works, and it's from F1 car! Bloody brilliant stuff!
Surprisingly F1 parts are so much better to learn the basics of how car components work because even though so much goes into them they’re very simple. They’re straight to the point instead of adding fancy things for reliability and comfort that production cars need
same.. I'm really surprised that I understood this video.
Ah, so the the gear sits on a bearing and it's the dogring that enables power transfer by engaging with it! Cool vid👍
It took me like 3 other animation videos to understand how manual transmissions work and I was stll left with some gaps of uncertainty. This video did all that in a single take and cleared up any remaining uncertainty.
@@neurofiedyamato8763 this really isn't about general manual transmission, it's sequential manual gearbox.
as a home bike mechanic, it's fascinating to see the similarities and differences in our drivetrains ! thanks !
That is what I was thinking. I've just rebuilt two 1998 Yamaha R1 engines. Straight cut gears, no synchro. Plus I like the way the selector forks sit over the selector drum in this video, Very tidy.
its amazing and beautiful how smooth these parts operate even when one end of each shaft isnt supported, the precision machining is perfect
Both shafts are supported on both ends via roller bearing.
@@borutgoli840 ...the OP was referring to the setup, that was being demonstrated on this video..
Hi! Nothing beats the real thing. Thank you for showing us this kind of stuff!
For me, this (5:20) is the most amazing piece of the car. It’s almost inconceivable that this relatively tiny set of gears can survive the stresses of an F1 car. Much more so than the engine, suspension or even tires, this seems almost magically durable. Thank you so much for this!
Well, the pistons have a lovely time.
Peter Yianilos plus as he said, the gearbox housing is the mounting point for the rear suspension. The rear wing also mounts to the transmission or maybe the diff. So you not only have the the internal stresses of the engine's output, but those external stresses. All of it made as light as absolutely possible.
7-800 hp through that? unbelievable.
Also at 4:14 he is describing a great bit of the gearbox.
This is so beautiful to look at. Actually amazing how simple the mechanism works and yet so smooth
Thank you for this video! So, the selector shaft and shift forks are a "simple" cam-and-lobe type setup. Brilliant. This unintentionally demonstrated exactly why sequential gearboxes are sequential and why they can't skip gears like an automatic or true manual. This was super informative, and again, thank you!
The most soothing gearbox removal I've ever seen
So true XD if all cars gearboxes were done like that
The beauty of a cassette gearbox
Im always amazed at how small the actual components are considering how much load is being put through them. You would think those tiny splines and dogs would never be able to deal with the forces at play there.
The torque of these motors is not super high
Small but sure are made from some witchcraft material lol. And smaller parts should translate to less twisting I suppose
I remember an F1 driver (I think DC) describing the crank shaft as being like a coat hanger bent into shape.
@@Shadowboost not crazy high torque, but consider the load these goes through, especially with those big grippy wheels
@@MrSutekii I design rocket components for a living, so this is nothing :) my fasteners take 300,000 lbf each. And I have three hundred of them ;) with the right metallurgy and materials used, those splines are plenty strong.
I am trained to AMIMI level, and this is one of the best explanation of how a gearbox works I have seen. first time I have seen the layshaft being driven rather than a separate mainshaft, good idea, one less shaft/bearing combination to worry about. Good job!
i was waiting for forever to see how a gearbox actually grip gears together, thank you so much for this amazing video !
Brings back memories, I worked on the gearbox and traction control unit for the 193 and 194. Shift times were 10 to 25ms as I recall, coordinated with a momentary ignition cut using the same interface to the engine management as the traction control. It would automatically retry shifts if the dogs hit face-to-face as happened occasionally and inhibit shifts that would over-rev the engine. TC and over-rev protection banned in '94, the FIA came in to audit our software. Happy days but extremely hard work!
Can you “guess” a little how modern seamless shifting works? Is it done by two output shafts like a DCT? Or as someone said, just try overlapping the two sequential gears 1~2ms and make the shaft absorb the twisting torque?
For me it seems very similar to a production car, minus the synchro rings. This example is really a good one because it's actually cleaner and more simple than a gearbox from a road car : no reverse, just two shafts and two sets of gears, the shifting mecanism is also beautiful by its simplicity (vs the complex forks on a H pattern shifter). I just wonder how it manages to shift smoothly, even if it's not the main concern for a F1 it's still important for reliability and predictability, but I guess it works perfectly ! Thanks for the video
Production car gears are much longer and aren’t straight cut. They’re helical gears, to minimise noise and make the power delivery smoother. Also a lot heavier as you can imagine.
It actually has reverse gear
How it manages to shift smoothly? Its not smooth. Its violent. The gears are just pushed in by the pneumatic cylinder. And I think its beautiful
6:56 am more curious on the integrated barrel and fork slider's mechanism!!

Well, that was one of the best and most informative videos I've seen. Never understood gearboxes before, now, so simple!! Very well explained.. cheers Scott!
wow, really impressive not only the video itself and your absolute clean explanation, but even more the beautiful piece of engineering of this F1 gearbox. I did not know how it is working, now it is clearer. Many thanks!
I really appreciate these kind of video's! I've always searched for content on youtube that explains the way a car(and it's parts) work. This was for sure one of the best video's I've watched about this kind of stuff. A big thankyou for that, and sorry if my English isn't that great (:

@@mosca3289 thanks!
Hi, mind a normal car gearbox is much different than this. This is essentially a motorbike gearbox but modified for racing, very similar to the Kawasaki H2R gearbox
Oh and I'm not saying that F1 copied that from the bikes. Cheers
Very similar to a motorcycle gearbox, except it's about 2x the size so it can handle 10x the power.
Those gears are smaller than my goldwings.
Agree, look the shifting gear between lay and main Shaft, no synchromesh there.
OldLeatherHands&Friends weight concessions and shorter time between overhauling allows the smaller components ....
@@fauzimachamili1691 Yes, no synchromesh. Only dog clutches, and straight-cut spur gears, rather than helical-cut gears.
Synchromesh slows the gear shift time. With revs matched a simple dog engagement is much faster shifting. It also allows clutchless up shifts.
Very well explained, thanks for sharing, and what a beautiful piece of engineering 👏🏻
Before opening the video i thought i wouldn't understand a thing but it was really well explained and i got everything. Really good job.
4:14 Ha! Got ‘eem

First video of yours I've ever seen and this is excellent honest content, subscribed.
It was so reassuring to know how actually the gears engage, thanks.
What a gem of a channel I've found! Having rebuilt my own cars' gearboxes in my youth, great seeing inside a sequential gearbox and its use of spur gears over helical on a road car - and of course no synchromesh.
4:13 got em'
lol was wondering if anyone else heard
My mind was wandering the entire video EXCEPT for that exact moment in time
Really good video! Explaination was spot on! Thanks for this!
More of these please.! Really interesting to see inside a sequential gearbox, and you clarified a lot of things I was confused about.
This is exactly the level of detail I’ve been looking for, thank you!
Great explanation of a sequential gearbox. It explains why my motorbike can't skip a gear when shifting, since it has a sequential as well, right?
Correct!
And at the right rev you dont need clutch as well ... this thing is exactly the same as the motorcylce one@@Driver61
At the right rev NO gearbox needs clutch
This is a sequential, constant-mesh box which is exactly the same as you would find on a motorbike. It's also one of the most simple, straightforward designs for a gearbox you can find.
@@Stoney3K Same selection system yeah, but don't bike gearboxes have synchros? (genuine question no bitchy crap)
Love this video, it's helped me so much while building my own 3D printed F1 gearbox. You can only stare at so many pictures, being able to watch you disassemble the gear stacks helped so much.
sheesh good luck man sounds like a project for sure
Beautifully explained! Made simple and easy to understand. Another reason I love F1. The engineering artistry!
Fascinating, many thanks. Been driving cars for years but never really know what the inside of a gear box looks like. Love this video and looking forward to more.
Would be interesting to see more about the diff
Here it goes kzhead.info/sun/rL16p5txampsioE/bejne.html
Hi Mr Crab if I’m not mistaken there is no differential action on this particular car!
Maybe the diff is further down the drive train?

Thank you. I've wanted to understand how a gearbox works for a very long time. You explained it well. Good job!
Currently designing a gearbox for my engineering project at uni and this was incredibly helpful! Love this channel!
Things like this should be on Netflix or tv. Man I love this. 😍
no it should not be, its better here. netflix and tv is trash.
These videos are amazing. The engineering that goes into this really is exciting and mind-blowing. Just the gearbox appears simple but it is so complex as the accuracy and quality that goes into it. These F1 engineers are truly masters of their craft.
Awesome vid! Your explanations are clear and concise; thanks for going through the effort of tearing this thing apart and explaining each bit! Subscribed.
that is freaking amazing !!! all that power going through that tiny little input shaft ! and the way the shifting forks move is an incredible feat of engineering . great job 👏 of explaining how it works . thanks .
GREAT video dude! Since you're there, I've always wondered about the tiny F1 clutch and pressure plate assembly!
Ok... I'll have a look at a clutch!
Look up Tilton or AP for an overview of what tiny racing clutches look like. They likely use a 4.5" multi-plate clutch.
Absolutely excellent vid dude. Explaining with the real thing in front of you. Beats any number of diagrams and words hands down. Cheers. Keep up the good work.
The best explanation of a gearbox working I've ever seen. Can you please make a video on how the gearbox transfers the power through the diff in a working example like you just explained the gears. Keep up the super good work brother. You deserve a million subs.
I personally thank you for your post, it is sublime, your explanation is great. Keep doing such videos
I believe that what you call a layshaft is, in fact, the input shaft. A layshaft is defined as: A layshaft is an intermediate shaft within a gearbox that carries gears but does not transfer the primary drive of the gearbox either in or out of the gearbox. A layshaft in a car is used almost the same, but the input and output shafts are in line. The power is transferred with an extra gearwheel from the input shaft to the layshaft. The principle of this gearbox is very much like a motorcycle gearbox: straight gears and dogs. Motorcycles also have a separate input and output shaft, but on most the moving parts are on both shaft. But a really nice video!
Yep, that's the input shaft. A layshaft is also called a counter-shaft in some manuals. Straight spur gears like that are louder but stronger than helical gears, which is why one is used in motorcycles and race cars and the other is used in passenger cars.
It's actually interesting to consider that on a mechanical complexity level this F1 gearbox is very simple and is more comparable to a car gearbox from the 50s. A "modern" car transmission would be far more complex with synchronization, over-speed lockouts, double synchronized gears, synchronized reverse etc.
@@immikeurnot - Helical gears themselves are actually stronger than spur gears but they produce thrust loads requiring more robust case designs/components which are therefore heavier and larger
*has a gearbox with perfect little wells to fit a ratchet* *used a wrench anyways*
exactly :D
First thing I noticed. The Snap-on man hasn`t been yet? :)
when you post your video of the workings of something like this, make sure you use your ratchet then, ok?
@@timmaaynoob2975 fucktard
britts..
Wow! That was so well described, well done and keep feeding the passion you clearly have.
That is one incredibly engineered gearbox. Be a fan i see and know how many times per second those gears shift up and down down down and complete the turn and in a split second its changing gear to the next and so on etc. It is so amazing and i really appreciate you taking your time to help us fans of formula 1 🏎 better understand and get a great look at the gearbox. Thank you my friend.
This was bloody fantastic! Again!
5:00 I didn't know that F1 gearboxes had such a cassette system for taking the gears out of the gearbox. Sure makes replacing the gears a lot simpler than fidling with the parts inside the housing. The fasteners that hold the cassette on place were also surprisingly little considering how much power F1 cars have and when you have wheel hop with those sticky tires, the forces the gearbox sees are insane.
Excellent description of the gearbox operation. The shifting mechanism reminds me of a motor cycle unit. Thank you for the video.
Wow that was amazing to watch, the level of engineering in that F1 gearbox is insane.. thank you for a great explanation, please upload more technical F1 content if poss in the future. 👍👍
This was very interesting. Great video!
WOW, Such a precise and clear explanation !!!! I feel like I can teach a class XD
One of the best F1 gear box explanation. Love engineering. Thank you for the video.
This is incredible. So simple and effective, but a real work of engineering
I subscribed because of this. Make it even more in depth.
That was awesome! I feel like I've learned something (actually, I know I have).
Your videos are like oxygen for an enthusiast like me. Awesome job. Greetings and many thanks from Brazil .
Many thanks for that great work. This brilliantly completes other videos I found on other youtube channels about gearboxes. This is a great video.
A motorcycle transmission like on a GSXR 1000, for the most part, works and looks the same. The shift drum on the F1 is a good bit nicer. Very nice thanks for posting this.
Yep ! Years ago I noticed the same thing. Did F1 learn from the Super Bikes, or the other way around ?
@@lroy730 Since bikes have had sequential boxes like this since the year dot, F1 took the idea from bikes.

What I'd like to see would be a 1986 Benetton qualifying gearbox !
abcd efgh why not a 1987??
@@bacburrito4225 iirc 1986 was the final season before boost was limited to 4 bar. Ie the most powerful F1 engines ever were likely the 1986 quali engines. I think BWM and Honda were rumored to be 1400 hp.
Such a good video! Very detailed and explained very well!! Not many videos out there about f1 gearboxes!
Fascinating! Love the videos, good to see the channel going well!
An F1 nerd's wet dream opening up one of these. Wondering why the gears are paired? Ie 3 and 4 appear together, 5 and 6, except 2nd, which is on its own. Also, how do they change ratios for different circuits? Eg, 1st and 2nd in Monaco may have different ratios for Monza.
The ends of the shafts have a retainer that keeps every thing in place. You remove these and change the stack of gears so to speak.
Lagibizar first is machined right into the main shaft on road cars
It's a cassette style transmission, the whole thing just swaps over for another one with different gears installed on it, similar to my turbo bike kzhead.info/sun/f5SmpNubmKGOd6c/bejne.html
I’ve worked on many formula car gearboxes in my previous employment. The reason the gears are “paired” as you say on the shaft is because the shafts are only supported by bearings on the ends so you want your highest loaded gears closest to the ends of the shafts where there is support. 1st and 2nd gears are next to each other on one end of the shaft and then you switch to the other end of the shaft for 3rd and 4th. As you shift gears higher there is less torque produced so there is less spreading force between the gears. If you placed 1st gear right in the middle of the shaft the spreading forces because of the amount of torque involved will flex/bend the shafts. By putting the higher loaded gears at the ends of the shafts you are putting them where the shafts have the most support from the bearings. That is the only reason the gears skip around on the shaft. The groove in the barrel that moves the shift forks through the shift pins is machined to operate in this order.
@@taratownsley668 Thank you for sharing your knowledge.
7:56 ineed for spiner replacement
Holy Cow my man, quite new to the channel, I cant say how insanely good at explaining you are! (the actual gearbox itself helps) I just might understand the whole car when you are done lol.
its so beautifully simplified, im so grateful, thank you for such a cool explanation,
Some good info' in the video - and a lot of 'less good' in the comments. You may have noticed a shaft coming out the back of the gearbox, near the bottom - that is a starter shaft - an external strater is engaded there to start the engine. The input shaft isn't connected 'directly' to the engine, but via a clutch assembly about the size of a large man's fist - worth a separate story just on the clutches, perhaps? most performance and race gearboxes are gas operated, but the speed demands of F1 means that is too slow and hydraulics are used. That isn't a layshaft, it is an input shaft. Some of you who have some experience in race gearboxes may have noticed that the input gears are machined as part of the shaft, rather than splined on - this is because F1 gear ratios are fixed (one change allowed mid year, if that still applies) and it is stronger and lighter to build them that way.
When you popped the rear case off, I said "oh, look - there's reverse.... and it's gone." No comment on reverse??
They have neutral and a crew to service the car, that crew can push the car backwards. Reverse is a waste of space and materials in a vehicle that is built to only go one direction 99.99% of its life.
@@oldleatherhandsfriends4053 Thats not the case anymore. Todays F1 cars do have a reverse gear and you better use it because If you need someone elses push to get out of a deadlock, your race is over.
@@Chuckiele interestingly, modern F1 cars shouldn't necessarily need a reverse gear, they could pull the clutch and reverse the polarity of the electric motor. Of course that would only be the case if the motor is after the clutch, which, after reading the technical regulations, turns out to be illegal. I tell you, the engine regs fucking suck, they leave almost 0 room for imagination. And it's not like they do it to keep "road relevance", variable geometry turbos, twin scroll turbos, VVT and VVL are all very common among modern roadcars, yet they are forbidden by the FIA. The regs are so tight that they might as well make the entire PU a standard component, I could write a massive paragraph explaining why having such tight regulations is stupid but it's late and I'm tired, maybe tomorrow. Here are said regs btw, I'm linking the 2022 ones because the PU will remain mostly unchanged and they show were the future is headed www.fia.com/regulation/category/110
@@jorge8596 They had to add so many regulations because things kept escalating and now they have to slowely remove them again. The aero cleanup is a good start already, finally undoing the ground effect ban but back then there was no way around it.

My Friend: What's inside An F1 Gearbox? Me: Gears
Well done. I still remember for those who had the money in the lesser classes, they had the gears on wooden boards with pegs, the boxes were often done rapidly during or after practice, or you had charts that told you the best ratios for a given track. As a mechanic, you had to recognize the worn dogs on the gears.
Fantastic explanation and demonstration, has answered many curiosities and head scratching, Thank you
Just like millions of motorbike gearboxes
Talita Slabbert even the little Honda 90’s from the early 60’s. Whoever did this first was a genius. So simple but complex to make it all work.
Exactly what I thought... I have a cassette like that, maybe even better, in my race bike! Hah.
The distance of the dogteeth relative to each other is bigger than my life.
Hi, Scott! First, thank you for giving a precise demonstration of the F1 gearbox. What amount of strength of steel are we talking about here, where metal is always up against metal, at the same time rotating at such high rpm's? An F1 car is such an engineering miracle that encompasses a multitude of technologies rolled into one. The gearbox must be right up there as one of the most important parts of the car itself. I cannot imagine what engineers have to do to design, machine tool, test and integrate into all of the other parts. This is why I appreciate your taking time to explain at least this aspect of the F1 car. I look forward to your next video. I recently watched another one of your videos on the pitstop crew, which was one of the best explanations I've seen yet. Thanks!
Never knew what happens in a gear box. Your very clear, step by step explanation- I understood it. Thank you. In 1950s went to watch F1 -and continue to watch it now . Looking forward to your next lesson. Pat the Dragon
1:10 - "this is conected directly to the engine" - really? ? what about the clutch?

How do they start then ? neutrall to 1st gear without clutch ?
@@mecabecane234 Oui !!! Exactly, from neutral to 1st you need either disconnection either engine starting in 1st.

@@ToomSugi They also aren't designed for tens of thousands of miles without repair like a consumer vehicle is. F1 cars will get their transmission changed multiple times per season. They can afford to withstand some extra abuse in the name of pure performance. On the flip side, I think it is amazing the kind of endurance that road cars have.
@@tankerd1847 motorcycle gearboxes withstand long mileage, vfr 750 engines can do 150k miles+ with no gearbox problems
You did a great job of explaining! Thanks so much Scott!
Superb and splendid explanation!! I really appreciate your effort. Keep it up.
Where's reverse? How does one engage it?
Reverse was nowhere to be seen in that gerbox in particular. When it is present, you would get it by downshifting from neutral, as in most sequential cars, or by a special button/lever as in automatic cars.
Papadakis Racing did a video on NASCAR gearboxes and they showed the reverse too. Check it out.
Reverse is on another shaft (not shown here) with a separate gear
In 1997 F1 cars had no reverse. It was made obligatory by new regulations.
Yes, reverse was shown in this video. It's the little gears at the bottom of the diff case when he pops that off.
It's.........beautiful! **blows nose**
This is by far the best gearbox explanation on youtube.
Easy to understand, hard as hell to figure out, calculate and manufacture such a beauty and such an intelligent pieces of work. How many types of transitions are currently in use today at F1? great work Mr. Driver 61. Keep up the excellent work!
