How to make a Go-kart Differential (From scrap)
I hate diffs...okay (and the laws of physics) ;)
In this video im showing you how i made myself a super small chain driven go-kart differential. Its purpose is to drive the front wheels of my 4x4 mini buggy. I think every go kart/dune buggy could use a differential to reduce tire wear and make for efficenter driving and cornering.
If youre interested in making a go-kart differential like this (with rear wheel drive), please keep in mind the axles should be supported at the ends, as well as in the middle.
Thanks for watching and if you have any questions regarding this video, please let me know in the comments.
follow me on instagram for updates on this, and other projects.

Not trying to be a jerk or any thing but you could have saved yourself a lot of time and effort just by using the axle from an old chain drive riding lawn mower they already have an identical set up as what you made and a lot lighter
Yup, but i didn’t have one... and don’t forget; making stuff is fun! also, this one is probably stronger.
@@homemade_madness yeah im thi k now your way is better the lawn mower axles are a lot smallee in diameter than remember
A
😂thought i was the only one who uses cans to make shims. Good shit.
Next video: "Improve traction of go kart by welding the diff!"
I'd say make a miniature Torsen diff
Some need this to for things like "rally go karts"
I feel a sense of pride that I recognized all the go karts at the beginning
Lincoln Lunt congratulations😁
Me to lol watch them all be built
me too lol
Same
@@JustinDeckardFamilyMan same😂
Meanwhile I'm welding my diff 🤣🤣
Vasily Builds 🤣🤣
lol
We meet again!
Maybe you could add a threaded collar or a pin setup that would lock the output shaft on one side to the housing, for a manual locker.
That is Raw ingenuity at play. Love the hand grinder application to machine down the hardened shaft.
Surely I'm not the only one who suggested the ol' "heat the bearing in the oven and freeze the axle in the freezer" to get them to go together...
For all critics....the 'Homemade' bit is the clue! Inspirational......thank you!
All the gocart he shows in the beginning of the video are home made u can woch videos of them making them on here
Молодец ! Не побоялся никакой глупой мелочи в своей работе.. Всё сделано из мусора, из того что нашёл..как сумел это сделать без понтов своими руками и мозгами . но, с какой искренностью сремления достичь этого желаемого отличного результата на выходе .Всё просто, гениально и доступно , и главное не лениться и не надеяться на кого-то... Я уважаю таких простых без понтов ребят !
I watched this when you built it and I have to say it has truly grown on me. I have been looking to purchase one of these and the places I looked may have had them but what name would you call it. Finally I came back and found your video and now to try and build it. Two years ago I did not even own a lathe and now I have restored one and then found a really great refurbished one in a grandfather's basement. Thank you.
I just want to say this has left me inspired. Thank you bro instant sub 👍🏻
I was wondering how doable something like that was for gokarts, glad to see someone actually made one!
I would think if you are building a differential for the rear drive of a cart, building it as a limited slip differential would yield the most improvement.
Absolutely awesome! Thanks for sharing, you're a very talented young man and I hope you can sell loads of them. Bravo!
Thanks!

Thanks, awesome! I want to build a pedal driven quad with front wheel drive. With an all electric quad you could just put two motors on two rear axles with a belt to a trailing arm suspension wheel. Electric has some nice options to simplify drivetrain.
well done and thats coming from growing up salvage yard and 45 years as machinist
1:12 😂😂😂 Man great video! You’re litterly the first one on yt I see making his own differencials, amazing work😜🤙
Thanks!🤙🏻🤙🏻
You are truly amazing my friend!! This is what I have been waiting for but really did not know it.
The concept is great, I would recommend making flanges for the whole setup so you can replace parts and adjust gear mesh with shims, especially if you are going to put a good amount of power in to it, just an idea I’m sure this is going to work for you and it’s fairly cheap 🏁👍🏻
Wow dude. You have a bright future if you keep it up machining, welding, and innovating. There is always a good use for junk. Good job man
Dude, freaking excellent!👏👏 ill hold your beer proudly while you fabricate this madness!
Just got to the part with the grinder on the lathe. . . Subscribed 🤣 its great to see "real world" solutions when you have to make do.
Damn you’re a freaking genius!
why's it's typical stuff in R/C cars diff...which strips, wears out. when it slips....slips..you might as will do NONE live ax. or jamm ear plug in it...lmao Most people shim it and or FILL it with super duper THICK OIL...to make sure it works. What he should do is mount another CLUTCH with different gear ratio for a SECOND GEAR..to get the low end torque and retain top speed. It's actually simple..if you have the tools to mill and weld the parts. The clutch is on the axle sort of like drum brake.
@@oneeyemonster3262 the engine inside of the build has gears on it already
9:30 at first I thought what a stupid id to drive one of the safts and hoping that some power will find they way to the other side. But your solution is GREAT!!!! Salute my friend!
Salute! 👊🏻
love your content!!! Can't wait for the next video
my immediate reaction: go karts dont need a diff, youll lose all the power because you (almost) lift the inside tire causing the diff to send all the power to it. the I saw the "Go karts" , yeah go for it
Well if you watch the video it is for the front of the go cart.
That is a cool little build :) , reality once you have a lathe and possibly mill lifes easy....try doing it all by hand haha. Keep up the hard work :) and practice
R.I.P those sealed bearings haha😂 good build though would have liked to see a more serviceable style i.e. with flanges or some sort of bolted mounting instead of welding in some areas but taking into consideration that looks like it was made out of scrap and a couple of new things works well for what it is nice work
I did notice that... perhaps push the bearings into the housings then the assembly onto the shaft? That way, with the right bushings turned up, it wouldn't stuff the bearings.
You did a very nice job building that diff. BUT, even though you added a grease fitting for the interior parts, if you have a bearing failure, you will have to cut it open to replace the bearing. Also, the welding heat draws the metal such that the internal parts down run true, thus causing increased wear. That's my opinion. Welding should only be used so far. I believe yours was excessive.
from an engineering perspective i would agree. but welding was the easy way out, and i wasnt sure yet how good the diff would work. if i would make one again i would use bolts like you say :)
That looks very cool. I will be trying to put one in my homemade G-Class soon :)
Vilebrequin approved
Kool am inspired to make one for my current project
Welding and grinding on a lathe Awesome
I HAVE drive a couple of those go-karts... and the actual GO-Kart fixed axle allows you to travel round a corner extremely fast due to all the load being on the outside tyre and the inner, even with an extremely low centre of gravity, will leave the ground. The instant you lift a cheap differential off the ground all the driving force will follow the path of least resistance (i.e. wheel spin) and you loose forward drive until the wheel contacts the ground. SO... if you want a kart to turn tightly at slow speed... use a differential... If you want to do it at extreme speeds (the whole idea of kart racing) then use a fixed axle (or a very expensive limited slip diff). As for kart racing, a limited slip diff would probably negate any advantage with the weight disadvantage (also notable in its rear position). As for the long suspension vehicles pictured (which are starting to leave the realm of "kart".. it depends on use as to whether a fixed or limited slip would be an advantage. Anyone that has put their rear wheel drive van on full lock and expedience the inside wheel spinning may realize the concept of loss of forward thrust due to 'Burning rubber' (I use a van as an example as although it has suspension, it is fairly stiff, especially when empty.... just like a light weight racing kart.
You're a bloody gun mate! Nice work!
Realy a cool idea bro keep up I love watching it
excelent!! very smart! i want to see more videos working the diferential on pavement please!
thanks! soon! :)
@@homemade_madness Try this axle design out on ur offroad rig it provides the best of both worlds ... kzhead.info/sun/famig7iygl93ZXk/bejne.html
It´s comig together! Can´t wait till it´s finished! :P
Matyas Grohmann soon! 🤙🏻
When you added the sprocket i stopped understanding how it worked. Guess i`ll watch again. You are some sort of wizard aren`t you?
hahah i guess so ;)
It works because the differential also allows the non driven wheel/axle to go faster than the driven axle. The driven wheel will always have power, but momentum will push the non driven axle faster through turns.
And i thought you might have used the carrier as a housing, with axle tubes...👍good stuff
Hi! Loved your work..... just had one question what is the gear module of the bevels that you used and how much power is it taking!
Great build man! May I ask you where did you get all of those parts? I'm going to build my own now. Thanks for the inspiration.
Thenujaya Warnakulasuriya thanks, the parts from pretty much any diff will work. Its best to take a diff from a very small FWD car, then the gears are smaller but still plenty strong for a go kart.
Craig's list. The free lawn tractor.
Dude from scrap ? Awesome job mate 😁😁🤘🤘 still pissing myself laughing at the grinder on lathe bit 😂😂👍👍
Thanks✌🏻🤣
He has carbide tools. I saw them, or one of them, anyway.
Great work l love it thanks..super trabajo me encanta mil gracias
Real Nice built! 11:48 should have done that before sealing it to ensure no metal chips going in.
Amazing skills and vision, looks very nice.
Hillary4prison thanks🤟🏼
Awesome video and commentary man. I know it takes a lot of effort.
While I greatly appreciate your efforts and applaud you actually doing something, there are a couple of points that I would like to share on the way this nifty diff was manufactured. Make no mistake, doing something is always better than just blabbing. 1. Heat management. Try to stick to the sequence order of casting - forging - welding - machining - assembly wherever possible, i.e. on should try to avoid welding or machining an assembly as much as one would machine anything before it was actually forged. Heat tends to distort, no matter what precautions are taken, so I would instead have machined the final surfaces after having welded the two parts of the diff casing together. 2. Use of lubricant. Grease is not the optimal choice for your little diff. In practice I'd even bet that you'll be fine, given it is out of a car and only going into your buggy/cart. You could even get away with no lubricant at all. Long story short. High speed gears prefer oil designed for high pressure shearing, something grease tends to do less well. I know the gears will mostly see low relative speeds, but the casement will be spinning fast, making re-lubricating the gears more difficult. 3. Choice of music. Maybe not important at all, but what might sound good to you, may hurt someone else's ears. 😉 Sometimes less music means more viewers.
Dat heb je handig gedaan, top 👍😊
Feeling inlighted from your ideas well well well done 👌👌🍻
niko debruyne thanks bro!
It looks really excellent to me. Filled with grease it should last forever.
Treacle is good too.
It seems that if the side gears were beveled the other direction and the spider gears were swapped so the taper faced out instead of in that you could eliminate the housing around them. Do they not make them this way because its hard to make gears that way or because the teeth would be weak? In your case the housing holds the grease in, but in road vehicles there is a larger housing already around them.
Not to be "that guy", but you should probably have seated those bearings in the opposite order to obtain maximum support for the bearing race on both pressings. Probably won't matter as there's not a crazy amount of speeds involved, and waaaaay better than most (who just pound them in) fabs I've seen on YT :) Aaaanyway, definitely a sub from me.
Good job bud! Nice to see some young guys making the impossible possible! I have a drift trike and run pvc sleeves to make up for no diff. It would be awesome to make a diff for mine but ill just feel better knowing someone else did it :) You didnt mention what that diff came off of?
North Idaho lathe!! Hope you go viral man
Collin Kuhn yeahh! Lets hope so😉
Legenddd
Interesting homemade diffy. I think the spider gears are going to wear the inside of the tube and disengage early. You may want to add thrust washers between the spiders and the tube. Looking fwd to seeing your other vids.
What he said, radius doesn't match.
Excelente vídeo, amigo te encargo uno, lo necesito urgentemente. Me avisas cual es su precio con envío. Saludos desde Colombia
This is the video i was waiting for.. You have quenched my thirst
Dude... You keep this shit up and your channel is going to take off in no time!
I know it arguably already has but i mean like cars and cameras #'s
You are crazy man! 🙌🏾🙌🏾🙌🏾
Torsen is the king!! Your accuracy is a nightmare with the grinder! I gave up at 4:57!!
Go karting places need these lmao stop kids slamming into walls from thinking they can make the corner 😣😣
Thanks in a million. Great content. Awesome imagination. Grade: A++💥.....
Great video thanks mate would love to have the tools to try this
Very nice. But you have a nice machine shop to work with. Trying to figure out how to do one with out high dollar lathe and press and such
Came for the differential, stayed for the Poetry.
Love the idea but damn those inner bearings arent gonna last very long and will be a bitch to try and change. Ive had a need for a small diff like this for a while now so good to know its possible. Now i just need a lathe.
Wow I hope I can buy those set of machineries so I can also build a differential for my project gokart that is not built yet.
Lovely!
You should put two sprag clutches or one way bearings on front axles it will work great as differential. In the rear you could use diy lockable diff.
Yes it would, but i also want 4x4 in reverse gear😎
@@homemade_madness problem solved lol plz make this design. kzhead.info/sun/famig7iygl93ZXk/bejne.html
Since it should have heavy oil (~80w90, idk the model), instead of a zerk and really heavy grease, some "00" grease may be better. You would need a fill plug, though, because it is the lightest grease, which is just slightly thicker than the heaviest oil.
Awesome informational educational video experience Y'alls God Bless Ya 🙏
Builds a kart differential from scrap with tools that cost a fortune! 😭 I want such a workshop, too!
I was about to ask how you were going to lubricate the diff.
You could turn this into a locker by adding a dog clutch keyed onto the axle to one side of the housing. Use a lever with a thrust bearing to engage the clutch. I'm probably doing a bad job at explaining this, but be assured that the gears in my head are turning on how to stop these gears from turning.
I love the build. It totally makes sense, to use something like this. That type of horsepower would something like this hold up to?
Well being that all of the drive parts are still car diff gears as well as the spider gear shaft it should be more than any go cart you could put it on.
Yup, i tink 50hp should be no problem as long as you support the axles strong enough
ese es un trabajo muy profesional mi felicitaciones
For my kids pedal car I made a differential using 4” angle grinder replacement gear sets.
Nice one. Very inspiring.
in the perfect world there would be no war, no hate, no disasters and ..... no corners
0:25 good old Aussie icon VS/VR commodore 👌
Jahaa daar is hoor😀👍
Cool, I Learnd how a diff works from lego😂😂 Echt coole video’s groetjes, misschien in de toekomst een meeting met mastermilo? Film jij in je eentje?
CasCars haha. Ja zou wel vet zijn misschien ooit maar moet ik eerst groter zijn. Jup, doe het alleen.
I always say that bro, there is some awesome build but they have no differential so thank u for this. 👍🏼👍🏼👌👌
thanks!
That is cool man
Deze is ook fantastisch! Die intro... haha
🤣🤣😅😅
Well, if you don't want to build your own, or don't have all the materials, for the price of the raw materials and a scrap diff, you can just buy a Peerless differential. They are out of riding tractor/mowers and you can bolt a sprocket to the side of it, with only adding a couple holes to your sprocket to match the pattern. I used on in my 1800W power wheels build.
How much power could a diff like this handle? What about a 130 hp RWD street quad/ATV? :D
Litterally has an differential. Today we will make a differential out of a differential!
I actually sold a quad I had for 40mins and bought a road legal buggy straight after as the quad did not have a diff and wanted to push me out of corners
you got 3 arms I am impress
Good idea and we'll done my friend well done
This is a really cool video bud
Tampa Boys Customs thanks🤙🏻
You can save a lot of time by removing a differential from an old lawn mower.
Lawn mower differentials are geared WAY TOO LOW, just stick to a solid rear axle and CVT, you’ll have to do a bit to them before u can make them work for a long period of tome
The "Stormtrooper" you showed was actually called the Cross Kart built by Cars And Cameras on here.. and while they used Miata rear suspension on it, it does just have a straight axle so.. yeah I'm sure it doesn't want to turn the best but you'd want a locker or something in it or you'd just spin on tire all the time with that CB750 engine it has in it.
Yes i agree, lockdiff would be best
A neat idea, but it nullifies all of the engineering thst goes into designing a kart chassis that Jacks properly.
Yes. I don't think that the creator of the video knows about jacking.
What is jacking
@@dangerdylan5005 When you turn the steering wheel on a go kart, the outside front wheel raises up, lowering that side of the kart, while the inside front wheel lowers. (ie while turning the steering wheel to the right, the kart rolls to the left (same roll direction happens when you drive a car in a turn. But in Karting it happens even when you're stationary) ) This makes the outside rear wheel to carry more of the overall weight, and the inside wheel carries less. Now during a turn the inside rear spins faster than it needs to (since there's no differential), and the fact that it's jacked up means that it is free to rotate faster without affecting the stability of the kart or wearing off the tyre too badly. This can only be achieved in karts, since they drive on smooth asphalt. Karts have great power to weight ratios because they forgo suspensions and differentials. They get away with not having a diff by chassis flex and jacking.
Good work other than potentially frying the bearings, not allowing any maintenance since there is no way other than grinder to open it, those bearing do not have way to get oiled and grease only have one way out, the bearing seals. Also grease will hamper gears working so its stiffer that could be beneficial in this setup but it should be stiff oil instead.
Awesome video ... btw whats the music name ?
That was fukin excellent, damn I need a lathe
😱😱
