For anyone wondering what is the purpose of the center differential Ok so i will try to break it down, get ready for a long but hopefully educative response. The differential allows one side to spin at a different rate than the other. Same concept for the differentials between left and right wheels, or the differential between front and rear wheels. Extra knowledge before we dive in: the front and rear differentials are necessary because when making a turn, one wheel will spin more than the other (lol geometry) Now for the main event A center differential isnt necessarily "better" than stock depending on what you want to do. On paper, differentials "send power to wheel with least traction" which sounds counterproductive but heres why they are used. For rock crawlers, you would want a locked differential (or no differential at all) so if one wheel goes in the air, it wont just unload (take all the power) and spin by itself while the others are on the ground with no power being delivered. However, for something as wheelie-happy as a revo, you want the power to go to the "least traction" because of the following No differential: You are at low speed/not moving. You jam the accelerator and BAM vehicle starts doing a wheelie, all the weight transfers to the back and lifts the car on its rear wheels. You keep the trigger jammed, car keeps doing a wheelie and possibly flips onto its back. This is "bad" because it puts all the force on the rear differential. With a center differential installed, the moment the front tires come up off the ground, the power "cuts" off from the rear, and gets sent to the front wheels that are still in the air (unloads on the front). This essentially stops the weight from being transferred to the back. Since the rear wheels "lost power" the wheelie action stops, and lets the front wheels lower and catch grip. The moment the front wheels touch the ground and catch grip, rear wheels will gain power again. This all happens in milliseconds. So the end result is that all 4 wheels will be planted to the ground equally delivering power, instead of having it all transferred to the back. PS: i should prob get back to studying so wont proof read. Sorry for any typos. Feel free to correct me or add anything i missed. Hope this helps!

2:54 Don't throw that part away! Here I am 9 years later removing my center diff and reinstalling the locker.

You have the best tutorials on the merv! Thank you

Awesome video.. i'm waiting to get a mini eRevo, its great to see how it goes together, much appreciated!

Nice. Can't wait to see it up and running again. Thanks for sharing.

Hi nice vid! Just installed it on a stock brushed 1/16 Summit. Such a great mod and so easy thanks to your help!

My merv was pulling to the left last week on full throttle. Pulled apart my center diff and low and behold the diff fluid was low. I just put back in the stock center drive gear so I don't have problems in the future. Runs a lot straighter than with the center diff with fluid but now I need throttle control to control the wheelies. Such is life.

Great vid - just picked up a center diff today. W/o this vid I probably would have taken apart way more than necessary.

I put one of these in my Slash 1/16 and it handles much better. The turning circle is significantly smaller and it no longer plows when you let off the power. I'm surprised by how much traction the truck still has on rocks. The thick oil that comes with it does a good job of keeping power going to the wheels with grip

Thanks for your vids. Very helpful.

Good to hear that I helped you out!

Your channe has helped me so much bro thank you..

Thanks. I will!

Very nice detailed video

wow, jumped right on it. awesome. keep the vids coming. I would never of guessed that's how you pronounce that name. lol.

That I do enjoy!

It allows the wheels to spin separately which eliminates unbalanced power.

Good job

Nice up grade

I hated traxxas, but a slipper and center diff means this drive line is bulletproof, I've never seen something like this, this will be my next RC car

ohhhhh cool

Me too !

I recently bought the centre diff and although it felt a little oily, I persisted and opened it to discover it was totally empty of any lubrication. I’m assuming a very light lube was used at the factory but it’s definitely not enough for aggressive use.

Your transmission looked rather dry, am I wrong in assuming I should be adding a bit of grease in here to help prevent wear?

Hi have you done anything to the oil have you replaced it with any other oil apart from the one that comes with it

So if I'm understanding this correctly having this center Diff will not only save your rear diff ring & Pinion but may also save your Spur gear from wear too if you are an aggressive driver or doing too many wheelies???

another great tutorial dawg, big fan. ever get a chance to open the center diff? I'm surprised you didn't since some have said their center diffs came in with barely any fluid. I run 50k front and rear and 100k in the center. power plants well to all four with this setup ya feelin' me? piece bra.

Hey I know this was 8 years ago and ill be flabbergasted if you or anyone respond, but im confused...doesnt the merv already come stock with a center diff? Cant it just be repaired and have the weight of the diff fluid changed to tune its characteristics, or does it not have a lsd stock?

It doesn't unfortunately. After adding the center diff I have not blown the rear diff again. (I went through a few rear diffs before). It does make it less spirited when driving though. I'm going to try a higher diff fluid weight and see if that helps.

Will this upgrade work on the 1/16 rally as well?

Wondering the same then picked up one. Not much of a difference. The biggest thing was the drive shafts and suspension system then sec and motor. Also made did the dual survo that sucked making then sync. Although a major difference in control. Can't find anything else that will make this little guy fly. Looking at the pinion gear and sprocket.

What does the center diff do differently then stock I really have to know this.

Kaleb Anthony depending on what you want to do with the car it will make the car be more "polite" so to speak . or more rude , cause that is the way you want a traxxas , rude not polite . these videos could be more reliable though... and should be informative as well... as you can see the video is about differential but you still don't know what it is.. you can lock or unlock a differential , if you lock it you will be looking at a bad ass crawler (just need crawling wheels) if you don't lock it you have a Traxxas , mothafuckin bad ass Traxxas . i do advise you to watch or read about differentials in Rc's though. it does make a very big difference when you know what to do with a diff...hope i was able to help

Yes. I have it and even put in 100K diff fluid. Waste of money. Turns front tires into pizza cutters. People add heavier fluid to make it perform more like the stock closed diff. Just use the stock differential -- the car is way more fun and no more ballooning front tires. I don't see the point in essentially having an open differential that allows the front axle to spin out of control.

Mine feels way less spirited and slower after the center diff install. Not as fun to drive but seems much more durable given I used to blow the rear diff all the time. I'm going to try 100k diff but from the previous poster, sounds like that won't help much.

Hang on here, if it's already leaking shouldn't that be dealt with first before install? I mean call me crazy.... Lol Update: after a lil research I discovered the diff does NOT come pre oiled, maybe shoulda checked that first eh bud! Lmao

no white lithium grease applied? LOL...
