The make the chain driven differential, I used gears taken from the BMW e46 2.0d differential. The differential can drive vehicles such as trikes, go-karts, buggy and other vehicles that will be powered by a motorcycle engine.
guys who can build stuff like this blow my mind. I'd rather watch this than some guy chasing a ball any day.
Good, because football's not on till tomorrow, anyway.
Me to !!

Welcome to our world of engineering and innovation, sure we make it look simple by showing results and some processes in between but our minds work differently to most with knowledge of materials,machinery,and step by step processes to create items. It's a craft we hold dear in our hearts and nothing can stop us because we fully understand that without us whom do this nothing moves forward nor gets repaired. We're a breed of our own who thrive on reinventing the wheel 💪
@@Th4thWiseman don't break your arm patting yourself on the back.
Not only gets upvote for the awesome build but also for letting us hear the sounds of the saws, grinders, arcs & whatnot without having crappy dance music or some such drowning it out.
👍
I love these kinds of videos. no stupid narration, no god-awefull music, just two hands, a shit load of powertools and their (slightly and tremendously sped up) sounds. making something that i myself do not have the knowledge and skills nor the immediate use for.
👍👍
Профессионал ❤❤❤ Можно часами смотреть на ИДЕАЛЬНУЮ работу МАСТЕРА !!! ИНСТРУМЕНТ ЗАЧЕТНЫЙ !!! РУКИ ОТКУДА НАДО !!! УСПЕХОВ !!!
можно уменьшить площадь фланцев крепления тормозных дисков. это снизив общий вес, инерцию. балансировка корпуса лишней не будет. отличная идея и Великолепное исполнение. Мастеру Уважение
Thanks for this... I'm building a very similar design of diff, but at a much smaller scale... It's for an HPV/ small EV with a power of under 2kW... My output shafts are 12mm in diameter, the outer casing is 70mm in diameter, with only 2mm wall thickness... You validated a lot of my design choices!
IMPRESSIVE! There is nothing else that needs to be said. From video idea, picture quality, sound and editing. All around one of the best video I've seen here on KZhead. Be proud my friend, your talents go far from just what you do in the garage
Thank you 😁
That was amazing to watch, a lot of thought and accurate measuring went into that one ! that looks like an ideal dif for a chain driven bike trike ! With the disc set up it looks like the jag 4.2 rear end i was using for a rover v8 trike i was building some years ago, that would have been ideal as a engineered minimised alternative as had to cut down the length of the drive shafts to fit 15" wide back wheels ;)
Man you are a freaking wizard! Appreciate your knowledge of tools and machines! Never think about chain driven diff!
Thank you :) But i will need this mechanism in my next project :)
👍👍👍
VERY IMPRESSIVE!!! That would be perfect for so many other projects!! I can't wait to see how you use it.
Thank you 😁
I had to watch this twice it was so amazing. It looks like your diff is leak proof so you might be able to put diff oil in it. When I did mine on my trike I had the prop shaft input flange cut into a sprocket but then I had to also use a bevel gearbox from a farm implement ( Rated 70 HP). That was ten years ago and it's still going around England somewhere.
That my friend is so cool!!!
Oh wow that's some serious work .. you make it look so easy . I'd guess a lot of planning and thought as well as precise measurements. Can't wait to see part 2 .
Yes, the gears from BMW differentials are not a good idea to make a chain driven differential easily. I am working on a certain vehicle 😁
You sir, are a first-class engineer, there is no doubt in my mind about that. Brilliant job.
What first class engineer would choose sleeve bearings over ball bearings on an axle? Those axles will be separating from the differential case in no time, if they don't seize up first.
I really appreciate the time you put in on these videos. Thank you.
Thank you 😁
I’ve been thinking of making this exact design for ages! Just went live axle for the buggy instead. LSD or locker would be so cool to have
This is one of the best channels on KZhead. Love watching this guy make all this stuff. Every videos is interesting
Thank you 😁

Love it !🥰Especially the inboard brakes ! Thanks for sharing 🙏
If i didn't just spend a whole lot of money on kart parts, trike parts, steel and then save for a couple more years, i might of had enough to make a tenth of the down payment needed to buy a lathe so i can build a differential. Thanks guy, i truly feel inspired 😅
Most of you people talking crap about this dudes work couldn't even imagine to do all the work he just did. Great video
👍
Классная работа! Талантливый механик!!! Респект!!!!
Cub Cadet lawn tractors used small Chrysler automotive diff assemblies for three decades. the rear axle/gear box assemblies have been a favorite transplant part for builders for a long time.
👍
I started watching this to get an idea how to build one myself since I wanted to build something that requires one for couple of years now, I think it might take some years still to be able to build one like this. Impressive! Good job! Maybe one day I'll use this video to actually build one.
You don't need to do anything this complex mate. You can use the original diff housing, and make plates to fill in the holes, and save all the machining. I've got 3 i use on my race car.
Very nice job! Well made and compact size!
Heat should not be a problem since there is no hypoid (ring and pinion). You should consider adding a ounce or two excess CV grease. It will find its way around as the spiders and side gears rotate. Then you can rifle bore one of the side flanges to vent into the CV without worrying of cross contaminating the lubricants.
👍
My thoughts would be to use o-rings in place of the paper gaskets and run a gear oil like a 75w140 instead of a grease to extend gear life and cut down on driveline noise.
@@Ratkill9000 main thing with this, when driving straight it acts like a straight axle with no gear spin which cuts a lot of wear
With great interest I saw your design of a chain-driven differential. You did a lot of technical operations to make the vision of this device come true, congratulations 👌.
Thank you 😁
I will now shamelessly steal this for my next build. Thank you.
This is an open differential, I can appreciate all the work it took to make and engineer, but as soon as you have any loss of traction it’s going to be spinning one wheel.
Мощный механизм отличный технический подход, спасибо за видео!
да, еще тут весь редуктор крутится будет... надо его еще как колесо на балансировочном станке проверять.

Pretty ambitious and impressive build!
Thank you 😁

This is art! Amazing. Please keep sharing your work.
Some of those scenes remind me Iron Man when he was building his suit! Excellent work.
Great work, i was at the scrap yard one time and saw a ball differential, it was lawn tractor size, should have bought it.
Also visit my channel, friends, there are interesting things to watch
Thank you 😁 Yes, in some lawn mower tractors there is a differential which is driven by a chain with a separately attached gearbox, my neighbor has one and he changed the seals in it and I saw what was inside and it seems to me that quite a lot of power can be picked up this differential :) But it is difficult to find such a mechanism that you can buy it in a few models of tractors, it was mounted, So if you come across such a mechanism again, I recommend you buy it as it probably wouldn't cost much:)
Props to your skills. Thank you 🇨🇦
that would make a sweet drive for a miniature tank or something similarly tracked , awesome engineering
Looks beautiful, very impressive workmanship. I'm wondering how much power it could handle though..... I'm planning a trike for my next project, and this has the look I want. I don't know if it can handle 200+ hp and about 950-1000 lbs. I guess there is really only one way to know. I'll be trying in the spring, but probably with a GTO rear..... I hope it doesn't blow up.
Really nice vid thanks for showing us! P.S. If you need a small sized, very strong diff that is REALLY light. Subaru aluminum diffs work really well too. Most boneyards have a few.
👍
I just need this for my project! when i get money later. I will be in need of your amazing skills
24 hours in a workshop like this would be heaven
👍👍👍
Awesome build. I want to build a 4wd go-cart with less than 10hp. Eventually, just because, I might try to turn it into an EV go-cart. Instead of trying to mount 2 motors, one and chain drive F & R differentials. 2 changes I would do on your build. 1, I suspect, was just not noticed during assembly. One pillar block has grease fitting facing the opposite way. It is easier to grease if both are in the same direction. The other is I would have put a bit more grease on the inside, not packed, but a bit more. All in all, it was a great build. Wish I had your lathe and bandsaw. 🤔
This is real professional! Very good, studied construction. Perfect realization. No unnecesarry doings - all movements aim to final effect like in master chess play :). Last not least, he doesn't afraid to touch elements without terrible lateks gloves (awful plague among so called "masters"), much better feeling of material (what I know from myself experience). Congratulations and thanks for real pleasure to watching!
It is also overkill and it adds a ton of weight to the go-kart and it will suck up some horsepower after the final weight. And it will throw off breaking. And it will throw off suspension.
And I love it and I love the overkill!!! LMAO !!!!
I need one of these for a trike build I'm working on. Perfect 👌
Make a well ("drill rig") that would get a lot of views...for all those DIY GUY... NICE WORK MAN ABOUT TIME WE GET A PROFESSIONAL DIY KZheadR KEEP UP THE GOOD WORK..
Very nice. I do see a tracked vehicle in the future. Just a kind word of caution. I would put some gear oil in the diff. you made. The grease will sling off the gears when at high speed and have no lubrication. Thanks for sharing.
Thank you 😁 There will be no tracked vehicle, but maybe I will undertake such a project one day. I am thinking of installing a valve that would reduce the pressure and pouring oil into the mechanism
The thing that separates this differential drive from what most are typically used to seeing is that it's chain drive, not shaft. This eliminates the parts that create the most friction and heat, the hypoid gearset. Second, it also eliminates preloaded pinon and carrier bearings, which is the second most heat generating parts in a typical differential. Unless this differential is used in a manner opposite of a typical differential, minimal heat will be generated because spider gears are not designed for high speed rotation and by nature of design do not create much heat unless high speed rotational differential speed is stained between one side and the other for longer periods of time.
Felicitaciones! Excelente trabajo!! Espero ansioso la continuación!! Un abrazo! Germán, Montevideo, Uruguay.
👍👍👍
Excellant idea isn't it ? Done this on an off road buggy 20 years ago. Stupid straight axle spurred me on to design the same thing.
Can’t wait to see what you build with it.
👍👍👍
Seems this probably saved Rather B Welding some time in figuring out. Good job!
Outstanding mechanical engineering to say the least.
This was a beautiful project. I do not know its intended use, but watch out for internal pressure from heat blowing out your seals. Most diffs have a pressure releasing vent for this reason. It lets the pressure out when it gets hot, and it prevent a vacuum when it is cooling.
How is the vacuum in a differential bad? I would like to know, thanks in advance.
@@zefror_7078 It can suck dirt and grit past your seals.
@@zefror_7078 can also suck in water and mud . Both cool down your axles creating a vacuum if your deep enough and don't have a vent.
He could just use heavy grease instead of differential oil/lubricant. He wouldn't have to worry as much about heat unless he planned on driving something fast. Or he could use bentonite grease. That stuff never seems to heat up. It's found in ride on mower transmissions in case anyone's wondering.
@@TheCommo81 It is not the oil or grease heating up that will cause the problem. It is the AIR inside. It expands and contracts with heat and cold, causing pressure/ vacuum as the case might be. All differentials should have a vent !
Great design concept, and well made. Would be a little worried by the noises!
Yes and no vent. But it will work. Could have used the oem Diff with a chain gear adaptor on the one side shaft and removed the pinion . would have been quite.
You never disappoint. Can't wait to see what's next. God bless.
Thank you 😁
I love your work! ,I hope to see more soon!
Stupendous work and brilliantly filmed as always!
Thank you 😁
Great skills involved in the project.
Awesome project and engineering, Sadly no-one mass produces these and should cause where i live steel alone might be close to $500 and then there is time + tooling required, where as its cheap to mount a driveshaft to the sprocket or to a jack shaft then run to a diff (which doesn't always work depending on setup). Def not bagging on your project i built designed and built a prototype but sadly one of my suppliers went to another supplier when they didn't have the specific parts in stock (after i told them that supplier had screwed me over and provided low quality parts that weren't up for the task), this ended up with my prototype in pieces and no way to recover the costs so it killed the project. Can also see why people like RPM stopped making them not due to demand but more supplier issues. Thanks for sharing, hopefully you inspire someone to build one for themselves.
Звук издаваемый редуктором при работе прям воодушевил, как у Форда Т 1905 года выпуска :-)
A little chat explaining sizes etc would have helped. Amazing job, but unfortunately we don't all have a well equipped workshop.
This guy with this skills reminds "Made in poland",great video,👍🏻
An awesome chain drive combined with a terrible open diff,looks like a good work just the same.😉
very impressive build as all of yours and congrats! looking forward its application (ina quad)? I know you will surprise me!
Thank you 😁 I'm working on a vehicle that will use this mechanism :)
I am so damn amazed by your work. Very Nice!
Thank you 😁
👍👍👍
I have wanted to find a way to rig one of these up for years. My dream project in high school was to build a tracked go kart and a differential would be a necessity to drive it.
Pretty nice. What ever you are making will be pretty cool!
Thank you 😁
*My congratulations for this transmission I think it is a good design and it is made with experience.*
👍
Pretty impressive work, dude! 😃 Looking forward to see how you use it! Stay safe there with your family! 🖖😊
Thank you 😁

I'm assuming the demonstration of the resistance to pulling out after showing the groove for retainer clips that you didn't install was suggesting that you weren't planning on using any. I don't know what your application for this will be. But you'll need more than just the friction from the seals to keep those shafts in place. Without a breather, just the pressure from the heated air inside could send them on their way out.
If you look again, there are retainer spring clips at the end of the splines of the stub axles. These are from a car application, unlike trucks where they use a large C clip/retainer. You would need a pulley or a hammer to get those axles out.
Really nicely done, thanks for posting
Thank you 😁

This is a very common tactic used in Formula SAE race cars. Many teams use Quaife out Torsen differentials as the starting point for their tunable limited slip/locking characteristics.
Yep, the norm used to be Taylor Race MKII (Quaife ATB), basically everyone has moved to the Drexler differentials at this point (multiplate clutch LSD(very similar to a KAAZ LSD)).
@@jeremiahjorenby2275 good to know. It's been years since I've been involved. LTU class of '02, Road & Track Triathlon champs!
@@gijoecam SDSU (the one in South Dakota, not San Diego) class of 2024. Our team is very small and low budget, so we're going to run our Taylor Race diffs indefinitely since they're unbreakable. The Drexlers are smaller and lighter, but not by enough that we're going to spend $4k upgrading.
Magnifica feina, m'ha ajudat molt per un projecte que tinc en ment, gràcies.

Thank you for sharing, incredible job! I’ve been looking for ideas to build one for my VW bug that will be powered by a ninja 1100.
Just turn the motor and run a driveshaft.
@@1985cjjeeper run a drive shaft to what? A differential from a truck? I want IRS.
@@MrSagerific95 Yes, use an independent suspension front diff with reverse cut gears.
@@1985cjjeeper or keep it chain drive and weld a chainring onto a Miata differential for about 1/3 the cost. Gotta think smarter. Welding is cheap, truck parts are not.
My uncle did this for me 25 years ago out of a vw swing axel diff. It was easier to build and indestructable.
Majster świetna robota cóż za dzień filmy dodajesz mam nadzieję że to przez brak czasu

Awesome job! 😉
Dziękuję 😁
Piece of cake... You only need 250 thousand dollars to buy the equipment and tools and take a 6-month course to learn how to use the machinery.
You should have done a quick test at the beginning to show the improvement in efficiency over the 90° drive... And also weight savings probably 👍 PS this unit also having inboard brakes will have less unsprung weight, better directed cooling and even dual calipers as an easy option... Cheers 🍻

You do some DAMN FINE work my friend, this is AWAZING.. Thanks for the video, I loved watching it...
Nossa que talento Adimiro a inteligência de um torneiro mecânico
WOW Very nice work I really enjoyed watching the video Please tell me what kind of metal did you use other than copper How much is left for measuring distance for hydraulic pressure For example, if the volume of the cylinder was 228.5 mm How much do you leave the distance of the tube that you are compressing from the inside? Do you leave it, for example, 228.5 or a little larger so that it sticks well?
👍
the 1966 Honda S 600 had a independent chain drive rear end . My dad has one .
I admire your talent.
Excellent work! Your differential is sealed so it would be better to use oil instead grease
damn good job guy. I'm impressed!
I did something similar with a Toyota solid axle out of a pickup. Made an adapter for the pinion to run a big chain link loop on a 30-50 some tooth sprocket to a torque converter I bolted to a ten horse tecumseh.
That was so cool to watch. I wish it wasn't so expensive to get used nice lathes to hawaii. I can afford shipping or the lathe but not both... cause I don't wanna let go of the boat. Lol.
Get a job with a machine shop
👍👍👍
Looks similar to how I did mine for my RC tank. I'm curious how you measured and accounted for gear backlash and spacing? I didn't see you put any shim's in for the spider gears.
Thats why they're chewing on rocks. Lol
I thought the same thing. Probably he will get some problems(whining, wear) when the backlash isn't adjustet....
👍👍👍
Very nice piece. A PLUS. carrier needs a grease zero and not sure if the pillow blocks will take the usage.
If it breaks down, then I will improve it, but it must be noted immediately that such a differential will not be driven several hundred thousand kilometers like in a car, usually it will only be used during weekends spare time :)
Amazing idea, amazing implementation! There are two things i would improve (it's no large expense): The bronce/ brass bearing slides without lubrication better than steel to steel, but they will last much longer if they get oil. Your housing is kompletly sealed so it should work without any problems, also in consideration of the low termical expansion. I would use something like CGLP 32/ ISO VG 32 and would fill it a little over half. The other thing is the radial spiral on the sealing surface of the two thru axles which was created by the feed: It will destroy the shaft seal in no time. It would be better if you dismantle the axles again an use sandpaper to polish the surface without any twist. Stay tuned, mate! Greetings from Germany, Felix
Also visit my channel, friends, there are interesting things to watch
Thank you 😁 The bushings on the axles are made of bronze. I have to check the oil, but I don't know if it would be necessary to install a valve that would reduce the pressure that could be generated inside. Surely your attention is very apt and i will have to take into account, can always improve the design😀
@@WorkshopFromScratch I've calculated and researched a little bit: A shaft seal is able to handle pressure up to 500mbar/ 0,5bar if the rotation speed ist less than 8 meter per second (that should be no problem 😂). I assessed around 600ml volume in your differential housing. If there are 300ml infill of oil (that the oil can be pulled into the gap between schaft and bronze bearing) and the rest is air with atmospherical pressure there should be a pressure increase through warming (difference of 50° Celsius/ Kelvin) of only around 220mbar. I would test it first without a valve. If there appears a leakage you can install the valve after that. The reason I would prefer it without the valve is the problem with the rotation of the housing and the centrifugal forces. In my opinion the valve needs a bore through the thru axles which could be a challenge.
Nice equipment and tools.
For a minute there I thought that I could do something like this… Then those 60 seconds passed and I realized that this is on a different scale than I am capable of with an angle grinder and a Harbour Freight welder.
I already had a differential from BMW and decided to use some of it, which made a lot of work, on KZhead I found a lot of great videos using differential from Mazda mx5 take a look at this video. In my country, such a differential is expensive, maybe in your country the purchase will be cheaper :)
just slowly build out your shop buddy, in time you'll be able to tackle more advanced projects.
👍👍👍
Bad ass man... you got the fab skills no doubt!
