Love how they took a 2$ tea tong, called it a diff dunker and changed the price tag to 7$ 🤣
No, its clearly a diff dunker! Dont you see it?
Just wanted to write the same😅. I bought my tea thingi @ the edeka hier in germany in the 1€ box-stands😊
😂😂Thats a tea strainer
do all three?

Definetely XDD
We used those for umm our powdered sugar yeah that's it powdered sugar!!😄
It can’t be.. tea strainers are wayy cheaper ....... 😂
Exactly what I said!!
I just started with RC Cars, this is the best rc channel to me. So much information and tips, greatly presented, I get exactly what I needed to know in every video so far and everything without headache at the end of the video because there's no in-your-face-screaming-chaos-modern-social-media-attitude ^^ thanks a lot, I'm gonna clean my diffs now.
Brett, you really are gifted with creating these presentations. Very clear, concise and valuable info. I appreciate your effort. And your table bongos rock!
He really is, he just doesnt try to sell you stuff, there is a lot of genuine value to their videos.
I always put diff fluid in after the installation of the sun gear then very slowly insert the spiders and cross shafts. This insures better fluid distribution especially with higher viscosity fluids. It also speeds up the flowing into and bubble waiting period. You can dab out excess fluid with q-tips if level is too high. I do my shocks in a similar manner.
I clean my shocks with wet rag make sure they are Dry then blow the hole inside of Truck ot with Dustbuster and spray the shocks front and back wheels to make sure they are cleaned and dusted out Excessive dirt then spray them with Dw40 or LuBRICANT SILICONE AND AND ALSO SPRAY AND CLEAN ALL THE ARMS FRONT AND BACK USE SAME PRODUCTS FOR ARMS TO 3 PRODUCTS I USE TO CLEAN MY VECLICE AFTER DIRT RUNS
Now i bought s product Called simple green u can spray it Everywhere on your Truck or rc car but blow the dust out first i use product Called Air Duster then i will spray the New Simple Greem product let it sit for 5 minutes. Wipe it down with a dry rag wait until it fully dries then spray Dw 40 om truck
Great video! Loved Brett's take on what tools you'll need!
Brett and the intro music are the best! Keep it up. 😃👍
Love the content! Thank you for sharing your experiences and tips its much appreciated 😁
3:22 😂 My FAVORITE part of this video!
I think I commented years ago on this but, You always do amazing work Brett.
Love the vids! Also, love that my main man seems to have a perpetual cold as he couldn’t sound more congested. 🤌😂🤘😎👍🤙
This was rally helpful, I just new in hobbygrade rc.
Wicked sharpy tip Brett. Awesome show 🎩🍺
This guy is so great, I could listen to him explaining how to clean a toilet.. I'd be here😂👍 -great info I was searching for.
I love the loose tea brew ball haha! Yeah, that's a super special tool lol!
I usually use my "diff dunker" for tee...
Minns när DJMedic visade upp en fancy multiskruvmejsel från Duratrax. Nu finns den för 20 dollar, men har för mig att den var närmare 30 då. Vad var det? Biltema 71-531 :P
Excellent vid!
Great video. Loads of information laid out simplistically. By the way, I have a Kyosho Fazer MK2 GT3 and would like to know what differential weight to start at. Any recommendations?
I just inspected the front Differential in my Rustler 4x4 VXL. It need some but ll do that next time.
Great info. Thanks!
perfect thanks!
Good to know, i bought a secondhand traxxas summit and found its front diff shattered internally, so i am waiting for new parts, then fill it and rock it
Amain hobbies= no nonsense straight to the point. Kudo's
Lookin DAPPER again today Brett!! Great vid as always: I was worried you wouldn't use a solvent cleaner, and I think it's absolutely necessary, so I'm glad to see you went for the full "proper" rebuild here. Still, I would've like to see you recommend a full tear down and soaking the parts in Naptha or similar, as it gets rid of all the extra dirt around those sealing edges...Cheers fella!
Yeah we'd like to give it a shot. I sadly hadn't heard of it before reading the diff dunker instructions but that looks like the way to go. I imagine it's available at a hardware store, maybe Home Depot in the states?
-Brett
@@AMain_Hobbies absolutely! I get NAPTHA from my local hardware store, so I'd imagine it's readily available almost anywhere!!
Great Video.
Thank you so much for making this video. I'm buying a bunch of different oil weights from amain to experiment with my tenacity db pro.
You did it, yay. Thanks man.
Hope it helps CloudFire!

Great video!
But i love this video though very entertaining and has many useful information.
Thank you!
Thanks Buddy:)
amazing video Brett! Covered everything. IS there a video covering the best weights?
No, it varies so much depending on the car and application. We usually recommend to follow the setup sheet for the vehicle.
-Brett
Nice video Brett 👍 I use PT racing diff clean. It breaks down the silicone with thinner silicone. No brake cleaner necessary.
Awh man, great tip! Sadly, I've never heard of it but it looks good and the price is right. We're going to look into this.
-Brett
@@AMain_Hobbies I think it would sell well 😉
@@GreatLakesRC Me too!
-Brett
Genuine question. Why wait for the air bubbles to come out of the diff fluid, if the manufacturer doesn't have reccomend completely filling (overfilling) the diff housing anyway? It seems to me that if we aren't filling it all the way, there's going to be air in the housing anyway that will mix with the fluid when the car is running
Thank you.
Nice video
This came out at the right time. Just got my Kyosho outlaw pro together and took it out for the first time. Diff is more slip than limited, so guessing I need to go with a heavier weight oil. I'm used to locked spools in my crawlers and just making sure they're well greased. Is there a reason things like the KORP and others have open diffs over being locked? More prone to breakage with high volt brushless set ups? Thanks for the content!🍻👍👊
A big reason is you just wouldn't be able to turn with locked diffs. Crawlers barely pull it off and must use extreme steering angles, a dig unit, or a front overdrive to overcome this. In sand or mud it is superior, but for anything with decent wheel speed, on a surface with decent traction, a vehicle with locked diffs would perform poorly. The diffs also help distribute power to areas with the lowest resistance, to keep wheel spin to a minimum. When your tires break loose and are spinning, you have lost traction and control of the vehicle. There is a lot to it, but I hope this shines a little light on the topic. Great question and congrats on the cool truck!
-Brett
@@AMain_Hobbies
Totally get it, guess I assumed everyone plays in the dirt, where a locker helps and you just slide the rear end around. Throttle stear, if you will. Never thought about high traction situations where the diff needs to the job it was literally designed to do. Appreciate the time and convo man, keep doing what you do.🍻👍👊
Just adding a 👍 from here.
Love you're videos! Very entertaining and educational thanks you've helped me from making some huge RC mistakes!!! #rcnoob

Can I use blue lithium automotive grease instead?
Is it ok to use brake cleaner instead of nitro cleaner ?
I have an HBX 2997a and it seems like more of my power has switched to the forward wheels over time. Does that sound like a Differential issue?
thank you
helo sir asking about the diff my diff always leak whats the problem is that can you please explain it to me why its always leaking tell me how to solve this problem or can i use lithium crystal ep grease p-611 or how many cst can i use for my diff thanks a lot your info
Simple brake cleaner works very well .
I miss working on my rcs 😔
I’m learning so much about my last unknown area of my truck, the entire damn drivetrain. I know, it’s incredibly important to take care of it, but I’ve never had any need or problems which required immediate attention. So I ask, if want to replace anything that may need to be while in there, my trucks an old 2.5 Revo, with several upgrades, but none to the drivetrain, yet. So any suggestions as to what could or even should be done while in there? I’d want to swap out the bearings as I’m just prone to always doing that. Any more than that I just don’t know. So any advice is welcome!!
Very happy you're exploring and learning about your truck! The r/c transmission are pretty simple but look intimidating. Usually for servicing, clean the inside the case, clean/replace bearings, freshen up the diff with new fluid, replace diff outdrives if they are worn, and maybe replace the idle gear too if it has any signs of wear. When you're re-assembling the transmission, add a little lightweight grease to one of the gears which will spread when all the gears are rotating, helping smoothen and quiet the transmission. This is what we use: www.amainhobbies.com/protek-rc-premier-white-friction-noise-reducing-gear-grease-lubricant-10ml-ptk-1412/p-qeaqtsqq6mzxactz

What's a good upgrade weight to do in all the differentials I wanting to grease the gears that are involved so might as well do the swap on the differentials.
Would it be a good to change fluids in all differentials and what weight. I running 20/50 gearing with Proline Trenchers HP Belted 3.8 I do not bash.
It's a tea strainer!!
(The "Diff Dunker")
Y’all can hate if y’all want but my closest hobby store was closed so I tried my Lucas oil stabilizer and it worked pretty nice up front. I tried bar & chain oil in the back because it was thicker. Really transformed handling and acceleration
thx
Hi friend, I'm from Brazil and I have some questions. I would be very happy if you would help me! I have already discovered that it is necessary to apply grease to the outer gears of the differentials, but I really wanted to know if I should also grease the gears of the engine. Example: 6448 parts: Spur gear, 8985: Input gear transmission, both from Traxxas Maxx. Another question is that the center differential gear comes into contact with a motor gear, should I grease it too? Part 8988. Inside Driveshaft 8949, do I also need to apply grease?
No, it is not necessary. The grease is good for metal on metal gears, but with a plastic spur gear it is not necessary, although adding grease will do no harm. The only concern is the grease will attract dust and dirt, so you may need to clean that area more often.
-Brett
@@AMain_Hobbies Nice! Thanks for the answer! I really want to keep my RC cleaner, with less grease even. I bought my Maxx from you guys! =D
@@wise--men Thank you Marcelo and congratulations on the Maxx! It is an amazing truck.
-Brett
Hi friend. On my DR10, which aftermarket diff oil fluid viscosity should I use to keep it running like stock?
Team Associated doesn't say what specific fluid they used, but I'm guessing it is about 5K. So if you want to keep it stock, 5K should do it. Unfortunately, the Team Associated fluid is all sold out, but this Mugen Seiki fluid is very high quality and a great alternative: www.amainhobbies.com/mugen-seiki-silicone-differential-oil-50ml-5000cst-mugb0322/p453219?v=1754

Thanks Brett.
I own a Kyosho Mad van. Only has a 2 spider gear setup that uses grease. Have the option to upgrade to a 4 gear set up with a recommendation to use dif oil. I noticed some people use grease instead of Dif oil. Is using dif oil better? Should I just use grease since my diffs only have 2 spider gears? Any recommended grease if so? Newbie here.
Grease can be purchased in bulk for cheap and is a good substitute for silicone differential oil. Is it better? No. Is it cheaper? Yes. For bashing, does it matter? Probably not, unless you are tuning your diffs or trying to achieve a desired result. The most important thing is to keep something in that differential; letting it run dry is baaaaaaad.
-Brett
I just bought an Arrma Typhon 6s V5.. when should I do regular service changing diff oil?
Please read your owners manual.
-Brett
can you use motor spray to clean old diff oil off the gears?
Yes, you bet. Nitro cleaner and motor spray are pretty much the same thing.
-Brett
the gnk basket is a ikea loose tea maker
is it possible to use vasiline if you dont have oil (i know it sounds rediculous )
From what i've read, Vaseline will melt with heat and friction, making it not ideal for this application.
-Brett
Could you please do a tutorial vid on how to sim differentials
Pro R/C Racer Ryan Lutz just made a video on this topic, so I'll link to his video below. He's a heck of a racer and he knows his stuff. Hope it helps shadowgamer.

-Brett
No o ring grease? 😁 so nice these days with all those nice accessories..
How do you know what kind of diff fluid to use? I've seen some people recommend white grease.
The vehicle manual should state what fluid was used, or recommended for use. If the manual doesn't state what weight fluid was used, they may have used grease instead, which can be a suitable, inexpensive alternative. The viscosity of grease though is not easily adjustable like silicone fluid, and naturally, grease has a lightweight viscosity. For 2S/3S power needs, this may be ok, but for high-powered 6S power needs, the viscosity may not be adequate. So, it just depends...
-Brett
Is that Protek RC mat available? Thanks
Not in that exact form, but there is a version of it with this mat: www.amainhobbies.com/protek-rc-10x11-magnetic-pit-mat-ptk-8152/p825365
And this crew catch: www.amainhobbies.com/protek-rc-5x9.75-magnetic-screw-catcher-ptk-8153/p825366
-Brett
What happens if i add thicker diff fluid to the existing fluid?
You could and it should thicken up the fluid overall, if that's your only goal. Typically though, if you spend the time and labor to access the diff, flushing it of all dirty oil before adding new is recommended.
-Brett
what is the part number for the shims used on the outside of the diff next to the bearings
For 1/8 scale diffs, it's probably these: www.amainhobbies.com/protek-rc-13x16x0.1mm-drive-cup-washer-10-ptk-h-5903/p188791
For a specific model, I would need to know what brand and vehicle you're talking about.
-Brett
What gear will give me more top end 14/45 diff .or 15/42 front
The 42/15 should have more top end of the two.
-Brett
Cool video is that from an arrma 6s .??
You nailed it. That is the center diff for the Kraton 6S BLX.
-Brett
instead of nitro spray or whatever that is called you can use break cleaner.
This was the comment I was looking for! Thanks
Is it better to have metal diff case than the stock plastic one ?
Yes and no. In some cases an aluminum diff case can help dissipate heat generated inside the diff. It can be especially helpful if you're in hot environments. But if you're not, it might not be worth it.
-Brett
@@AMain_Hobbies I have a v5 blx 6s notorious stunt truck and it’s not doing willies no more that’s cause I need new diff right ?
I just put 300K in my center diff on my typhon 6s what a difference that made now im looking at the front and rear any suggestions on fluids for both front and rear with a 300K in the center?
Whatever Arrma recommends. If you make the front and rear diffs too thick the car will have reduced steering and cornering.
-Brett
@@AMain_Hobbies well i just put 30k in the front 300k in the middle and 80k in the rear and it drives AWESOME no loss of steering, as a matter of fact it steers better than before much more responsive in every aspect
@@trimmin420 Excellent! Glad to hear it.
-Brett
Can I use Valvoline synthetic gear oil instead?
I don't know for sure, but i'm guessing it's too thin and would leak out. Black grease is a great solution for a light diff.
-Brett
a small glass jar and lighter fluid work wonderfully.
I am Newish to the hobby what is the best diff fluid weight to use just for bashing in a 4wd
Hey John. You'll probably want to use the same viscosity fluid that was in there, unless you're trying to change some performance characteristic. What vehicle do you have?
-Brett
Fs racing victory the one that drive on water. The diff gears in the rear keep braking I don't run it hard or jump it more then like 2 feet I air
Can you use synthetic grease for the diff?
I've read some people use that in their diffs so it should work, although not sure if there are any drawbacks.
-Brett
Great Vid. Wow!
I wish I could find a Fluid Video for my New Associated B74.1D Center Diff.
Oh I am on Bag 10 trying to get it Built.
And the weight part is just not working on the Center Diff for me,
and there manual Sucks for directions!
I Emailed Associated today, they just said go with the line in the Picture.
I dont want to Blow my New Diffs. Per there Warning!!!
Im so not Happy with this Kit at all..
There's no harm in filling the diff cup to the line in the manual. If too much fluid is added, pressure will cause some to seep out; if not enough fluid is added, the fluid will break down slightly faster. Neither way should cause the diff to blow out though, so you should be ok.
-Brett
@@AMain_Hobbies
I 100% understand about Pressures and what to Little or To Much can do even to a Automobile!
This is why I am Trying to do a Proper Build and not Micky Mouse!!!
PER Associated, It is important that the correct amount of fluid is added to the diff. Too much fluid may cause the diff to fail.
I DONT NEED OR WANT THIS!!!
Interesting,
If you think about it there is NO way a Liquid Line can go Straight Across! in a Cup....
Its going to be like a U or a V shape so that is Not a Straight Line!
So in Reality there is NO Real Line!
ITs also Interesting Associated made the kit
And they have NO Clue what the Dry weight is before adding any Fluid..
They couldn't even Tell me Properly all of what parts for the Center Diff that go on the Scale,
Because no matter what I had Put on the Scale Nothing would weigh 44.5g.
The Manual Directions are Typo'd so Bad!!!
No one knows how to Weigh the Center and that just Stupid for it to even be in the Manual!!!
Thank you
What can I do I have the Losi 8ight T RTR my front tires are spinning before the rears what can I do to fix that I don't race I just play in the backyard with the boys
Sounds like your center differential fluid might have broken down, or is too light. Adding new fluid would help, maybe 10K is the stock weight. The heavier the fluid, the more all-the-time 4X4 it will be, but this generally reduces performance, but if you are just bashing around, it shouldn't matter. We have used 1Million weight center fluid before and it's some serious wheelie popping action, although it's really hard on the vehicle drivetrain. Maybe try 100K fluid if you are just bashing around. Check this out (and you can select different weights from the drop down above the blue add to cart button): www.amainhobbies.com/team-associated-silicone-differential-fluid-2oz-100000cst-asc5459/p453215?v=223792
If you have a broken part in the drivetrain, in the rear end, this will cause all power to transfer to the front end. So be sure this isn't the case. Maybe pick up the car off the ground, and make sure all the tires spin with the same force, when you give it gas.
Hope this helps.
-Brett
Had this happen to me with Tacon truggy. I've used white lithium grease and shock oil in my diffs before, lol....
What weight fluid do u recommend on a 1/14 scale?
Shoot, not sure. I recommend seeing what the manual recommends and adjust from there if you need to tune them.
-Brett
How much Cst for front diff in trophy truck 1/10????
The instruction manual will know best what weight to use for your specific vehicle.
-Brett
And if you up the weight in the center diff what effect does it have on the front/rear diffs? What is the effect if you up or lower the diff weight in the front/rear diffs? A lot of questions a lot of RC car people have. I don’t think you addressed this in your explanation. Can someone with experience in this chime in and help educate us. Thank you.
Thicker the oil , more wheels work together instead of giving and causing one wheel to spin faster , center diff same principle thicker oil makes both sets tires work together , bashers use thicker oils racers use lighter oils , if go too thick puts more strain on other parts usually good to go little thicker
Paul Clancy so are you saying thinner oil is more like a limited slip diff and the thicker the oil is moving towards more off a locked up diff?
@@2shoestoo yes thats right.
Brett iam getting New gears for my it was not THE slipper Clutch it was the gears my Question to u should i stick with the plastic gears and shimme them or go WITH Aluminum gears or steel hot racing gears cause i know its going to happen again with New plastic gears the 4s has to much power for plastic gears should i shimm them would that help i watched the owner take off the 2 poles the 1 underneath to tighten Slipper Clutch and take off the.

can you use fuel to clean the diff parts
Yeah, fuel works good.
-Brett
If I change the center diff fluid, do I have to reset the mesh on a kaiju??
Not sure. Do you have to move the motor to remove the center differential? You should be able to leave the motor secured to the motor mount, and just remove the center diff. But i'm not that familiar with that vehicle so I'm not 100% sure.
-Brett
Ok.. No u don't have to remove the motor to get the center diff out. Thanks for the info. 👍
Is RC nitro cleaner the same as carb cleaner
From my understanding, most r/c nitro sprays are automotive brake cleaner; not sure about the carb cleaner.
-Brett
how do you clean a 1/8 elec motor
Give it a spray down with motor spray and add a drop of bearing lube on each end. Here are some items for reference: Motor spray: www.amainhobbies.com/search?s=motor+spray
And bearing lube: www.amainhobbies.com/search?s=bearing+lube
-Brett
Can you use wd40 instead of the nitro cleaner?
I'd avoid using WD40 because it's a better lubricant than a cleaner. Brake cleaner will work.
-Brett
One thing that would have been good to mention is dont over tighten the diff screws! I like to just use 2 fingers on my driver once there almost all the way down.
Yes, good point Alex.
-Brett
What if you put lithium grease inside? Will it explode?
No. That grease is a good lubricant but not very thick, or lacks a high viscosity. But it would work and it's better than nothing inside.
-Brett
I’m an old racer who only knows ball differentials for off road. Why did the industry change to gear diffs?
1/10 Off-road dirt racing still uses the ball diff typically. The gear diff has been used more recently as tracks tend to get more and more high-traction.
-Brett
Can brake cleaner be used?
As stated in the video: yes, but don't spray directly into the cup to avoid spraying the silicone o-rings.
-Brett
Damn I feel like we missed out on an awesome shirt.
What do you mean?

Kinda looks like you're hiding a colorful shirt under your sweater!
HA! Yes. Maybe next time. Good observation. Hope you enjoyed the diff rebuild too.
-Brett
Diff Dunkers ?? LOL, i use them for my tea.
Ha! The Tea Dunker.
-Brett
To me it felt like a shortcut diff rebuild. I usually tear them down compleatly and regrease all the seals after deep cleaning all the parts.
This is a video showing how to change the fluid, not completely rebuild the diff.
-Brett
@@AMain_Hobbies Still from my expirience fluid catches very fine dust from gears grinding inside and it can damage seals or increase the wear on crosspins if allowed to build up. In my opinion its worth to always do a full rebuild. Sorry if you took my initial comment as "trash talk" it wasnt meant to be one, more of a discussion starter.
i got an arrma outcast 6s from facebook marketplace a while back. went to service the diffs and there was NO diff fluid in there😂 always check your used vehicles guys, don’t trust other people’s work.
How often do i to change diff to put fluids in or or take out to clean gears Clean is all should be cleaned in kraton 4s
You shouldn't need to work on the differentials much. Like I mentioned in another comment to you, replacing the diff fluid doesn't need to be done much, but it depends on how many hours of use you have on the vehicle. But maybe a couple times a year would be good... even once a year would be great!
-Brett
Not much cause it keeps breaking down
@@AMain_Hobbies Thanks Brett for ur Time and patience
Brett iam going to get All Metal gears spur gear is plastic input gear is plastic to diffs r metal and put shims in between input gear and diffs or should i go WITH Aluminum input gears and spur gears to use on diffs
GEARS
What if is a used differneral i mean its my 4s kraton and gear does not have to be changed with its my input gear that's stripped do u still need to put fluids inside differential because the way u made it sound its my differentials that are stripped cause the owner of shop said it a 8$Dollars fix this is where iam Cunfused about this
Troy, I want to help you but it's very difficult to read and understand some of your comments. The only thing I understand from this is you asking if a diff should have fluid. The answer to that is yes. Differentials need to have some lubricant inside, whether it's a grease or silicone fluid.

Me: just rebuilded my whole car.
Me: realises that i did not wait too mcuh to release the air bubbles
Me: wanting to do everything right
Me: massive headache
Not mentioned but a heat gun also changes viscosity in the diff. Use a heat gun to remove old fluid and use it again to settle the new fluid. Waiting can somewhat be bypassed imo.
Good show for sure though. Every time I watch a diff video I gain knowledge and confidence. Arrma 6s getting more and more love outside the bubble too... more than ever now in 2020. 🥇
The amount of paper i use is insane i cant remove all of the old fluid outit gets stuck in forners i even use a flat ehad screw driver to help me out i dont like really using like brake cleaner i have a little leak on my diffs because my clear grease turned milky white after testing its oil mixed with grease im going to stay with the factory gaskets for now on migth also contributed to my diff getting worn pretty quickly
How about regular brake cleaner instead of the fancy and probably overpriced nitro cleaner?
Why worry about getting all the bubbles out of the fluid when you are leaving a gap above the satellite gears anyway? unless you fill the entire diff ( when it's all put together ) there will be air in there and when moving it will create bubbles? Maybe weighing the diff and fluid the manufacturer know the weight and knows it will have zero voids for air???
All that empty space is filled with the other sun gear when the differential is sealed together. If you did not leave this room, the two halves of the diff would not screw together.

@@AMain_Hobbies I get that you need to leave room. That's why I ask why bother getting all the bubbles out of the diff oil, there is room/air in the diff anyway
@@afarmer4The other Sun gear fills the space of that air when you put it together leaving no air space.
And Also when i Brought the Truck to the shop the slipper Clutch was Already tight and the before yesterday was my Run the day before that i got it out of shop All Ready to go so i thought just broke down again would not go backwards and.frontward going slowly so i shut Everything off
I often do i have to change diff fluid
Maybe after a few hours of use, it depends on how hard the vehicle is driven, and if performance is dropping. The differentials will spin much easier when the fluid is broken down, compared to when it's new.

Is it Best to put the shims in my to prevent THE gears from. Stripping went to the shop yesterday asked him about it he said he would do it if the Truck Needed it i want the shims put in weather they need it or not don't 4s kraton s Already come with shims?
Iam so tired can't Even spell Right
@@troyflanagan4237 I'm not sure if the diffs come shimmed or not. If the manufacturing was tight enough, it wouldn't need shims. Shims are a "as needed" basis. If it needs shims, then you add them. If it doesn't, you don't. But if it uses shims out of the box, then you use them. If the shop owner is going to shim your diff for you, let him.
