Hot racing differential assembly Arrma 3s 4s line of rc cars

[@rickbadessa4897]

Something you may want to make known... there's a small tiny bearing in the dead center of the middle of the diff where the "INSIDE" of the outdrives snap inside each other...only mentioning this because with all the parts out on the table and handling them..test fitting..etc..this small bearing could fall out hit the floor and not even know it...this very thing happened to me when doing my conversion over to the hot racing diffs ..hope this helps somebody out...great video and keep em coming

[@earlmoorhead5555]

I did mention it with the tiny washer in there it’s a bearing with a very tiny washer or shim in between the output drives (or pinions) thanks for the mention 👍👍🔥🔥🔥🔥

[@rickbadessa4897]

Earl if you're talking about when you mentioned the bearing and the one shim on the outside of the diff on the ring gear side ...that's not what I mean... I'm talking about the one and only little bearing on the inside of the diff... With a quick glance you wouldn't even know it exists

[@earlmoorhead5555]

Rick Badessa no not the shim on the pinion gear the drive cup pinions 👍👍🔥🔥🔥

[@earlmoorhead5555]

Rick Badessa it was at 10.22 with the O-ring but I did cut it down and it’s not clearly said 👍👍👌👌

[@rickbadessa4897]

@@earlmoorhead5555 still not sure we're talking about the same thing..I don't mean a shim or an o-ring...this is a very tiny bearing inside the diff...it's the only bearing actually inside the diff...do you know which one I'm talking about

[@hotracinghelpdesk7243]

From the Hot racing help desk you get thumbs up. I am always seeking good videos to send our customers to for instruction. I have subscribed and will likely send viewers your way. Well done.

[@earlmoorhead5555]

Thanks 🙏

[@nsbob70]

@hotracing, You should include instructions with your products. That'd sure save us all a bunch of headaches for sure. Just got my 50 tooth spur for my infraction, am waiting on diff housings for my spiral cut ring and pinion. Beautiful looking gears, very nicely made. Had to trim the little 'ears' of my slipper clutch disk to fit in the new spur gear though. No biggie.

[@Z28Ruiner]

Just what I needed, thank you. I too share your love for diff oil and greases.

[@nobodynoone3428]

Good stuff , I really like the tutorials on this kind of stuff , there isn’t many out there. I really wish hot racing would send more documentation on there products. I did find they have break downs on there Facebook page of all there products.

Earl it always blows my mind everything I order from hot racing including the soldering jig has no instructions high-quality product with no instructions can’t even find anything online about it thank you for taking time to make videos like this you think such a prestigious company what is the very least upload instructions online or make videos of each of the products they develop that way they can make money of views as well either way keep them coming

Great information and rebuild

[@earlmoorhead5555]

Island RC -Duke thank you 🙏

[@zqzj]

FYI, this will not fit in the latest Typhon 3S (v3). The input shaft is 4mm longer than the stock one. Looks like they got stubby in the latest models.

[@country_boy_ch]

It's a work that takes care. 👍👍👍👍👍

[@earlmoorhead5555]

カントリーボーイホビーチャンネル yes thanks 🙏

[@norcalrc]

you are going for it big time on this one Earl. seem like these are some of the things they should have addressed before releasing the 4s line. next upgrade will be dealing with the noddle like axlesshafts , yes?

[@earlmoorhead5555]

norcalrc thanks 🙏

[@earlmoorhead5555]

norcalrc I’ll be doing the shock bodies next since mine are still leaking 👍👍

[@norcalrc]

Earl Moorhead the shock bodies are the real deal. really like mine. they would have been even better if Hot Racing ever put directions with any of their products

[@earlmoorhead5555]

Thanks good video very informative

[@earlmoorhead5555]

Thank you 🙏

[@DJSpannamanUK]

I have found my output gear now sits 2mm further out when I get a good mesh with the crown. Now the power module won't click in. I'm shaving 2mm off the end so it's flush with the chassis like it used to be. At least I will know the module and drive shaft will not * be pushing that into the diff housing. Does that make sense?

[@erterrill]

Question for ya Earl. I converted my Typhon 3s over to 4s and I am thinking about going with the HR diff and yoke. How have you liked the upgrade and what oil did you ultimately end up using for front and rear for bashing. Again, its now 4s. Thanks and hope to hear from ya.

[@earlmoorhead5555]

The diff is awesome I just can’t keep a center dive shaft in it now so I don’t use it much anymore 😳😳🤷🏻‍♂️🤷🏻‍♂️

[@skipper581]

Great video. If I heard correctly that was the Outcast 4S. If so what tires are on the truck in the video?

Hi earl great video i have been looking at your diff conversion. I was just wanting to know how the gears have been holding up? Also how many shims did you use if you put them in? Thanks im looking to do my kraton 4s.

[@samuelpedroza9645]

Hey bud. Love your content been subscribed for a while . And I thought you'd be able to help me out solve why my mother don't seat all the way like if shaft from hot racing is to long. So it don't slide into the slipper shaft all the way.

[@bobbybrown5217]

now that's a tutorial, nice vid... does the yoke mod prevents the motor plate from bending or should i do both? ✌️

[@earlmoorhead5555]

Should do both

[@goodvibessounds4551]

would i need to save old gasket for new diff? also would i have any problems if i only replace the back diff... its the only one giving me problems on my arrma big rock... i replaced it with original parts firts but it broke again.. just bought the hr back diff. just wondering if it would cause problems if i run original diff on front and hot racing diff on back? please advice thanks

[@jayhenderson1544]

I just want to know how the pins line up on the ring gear! I've watched 3 different videos and not one of y'all show this step! I've been trying for over an hour and it will not go together! I've undone and redone so many times I could do it with my closed but I still can't get the ring gear on!

[@timonthornley2656]

Any issues with the input bearings to the diff failing due to the force applied by the helical gear tooth design?

[@wackpackxj]

While time I’m watching this I’m thinking PAIN IN THE BALLS!!!

[@zqzj]

There's nothing worse than diff maintenance lol

[@KO-wo6dg]

Boss what you think about upgrading to TP 4050- kv 2390 motor. 25.2v I'm just asking because I got one laying around. I feel to put it in my Typhon 3s. What's holding me back I'm thinking what ESC to use. I'm just trying to have a little fun speed runs up and down nothing to get overheated. Enough torque and speed up and down grass. And I love your work.

[@earlmoorhead5555]

That’s a powerful motor for a typon 3s the plastic drive shaft will not hold and the plastic differential won’t hold the power

[@jamiewellman6986]

I went to a mamba x 6s ESC and a 4 s capable 2400 kv castle motor in my Arma vortex..now I can't find any smaller spur gears to do on Rd speed runs with all I can find is 57 tooth factory spur gears..there running 34 34 combo on infraction and typhoon and doing over 100 on 4s any advice on the vortex?

[@christiansrcs7789]

how is it? would love to know i’m about to get it i just need to know if it’s any good

[@bobbybrown5217]

Hi earl, bought a HR yoke, should i install it in the front or back... or order another one to do both?? Thanks ✌️

[@EXTREMERC416]

Shim the diff if needed its an important step. Those diffs look so beefy they look bulletproof but you cant buy the rubbber gaskets or any part seperatly everyone would have been buying these otherwise

[@earlmoorhead5555]

Surchaufeur they are shimmed I showed that step and what side to shim and HR has a lifetime warranty on there parts but I can’t see any of these parts going bad I can see the diff gears failing but that’s a factory part but only time will tell 👍👍🔥🔥🔥🔥🔥

[@EXTREMERC416]

The issue with hpt racing is you have no way to contact them i email them a lot ntohing the only guy who helped me was the distributor

[@TheBigToe69]

Earl Moorhead Good luck with the lifetime warranty. I’m not hating on the product, it’s a really good upgrade but Hot Racing customer service does not exist.

[@kcmullins6179]

Is it possible to install a kraton 6s differential case n gearing into a kraton 4s ?? Not the bulkheads obviously but the 6s crown and case and yolk?? I wanna turn mine into 8s but like the size of the 3s n 4s rigs. But want a stupid strong set of diffs in the front n back. which stock they are pretty stout but wanna make em almost impossible to break ya know. Atm I got everything metal inside em but wanna go slightly bigger and wasn't sure if the physical size of the 6s diff gearing is the same size or slightly bigger I'd assume if it's slightly larger it should still fit wouldn't it?

[@Pursnikity_20022]

So if u wanna come to Hawaii an change out my diff. Can 😁 😂. Naa cool video. Thanks for this. It’ll eventually happen to me

[@justinsl33ps]

Hey Earl! So I just did the exact same install, but on my big rock 3s. For some reason, the rear one wont allow my motor to push all the way back in. I'm about 2mm away from it clipping into position, and it just refuses to budge. Did you have this problem? I compared the pinion gears length from the original and the new and they are the exact same length! So I'm a little beat

[@earlmoorhead5555]

They really the same but I’d make sure the slipper clutch pads are going all the way in and that it’s not backwards 🤛🤛🤛

[@43rocket]

hi, im having problems with my big rock diffs. I upgraded to metal g ears and new diff case but the gears mesh to tight in there , plus the stalk yokes make them mesh to tight why is this??

[@wackpackxj]

Any idea of the gears themselves will work with the stock diff cup?

Great for racing the thinner fluids help with tight cornering for me as a basher thicker is better for wheelies and backflips all depends on your style of rc 💯💯👍👍🔥🔥🔥🔥

So any weight is safe and I can just experiment on getting desired handling? I love the way it handles with thinner fluids but now the stock stx2 radio needs to go. The delays are much more noticeable now. Haha. Thanks for the advice mate! :)
