changing diff fluid?

[motoracer58]

Hey im new to the RC scene, i got some 50k diff fluid for my jato, im wondering if there is a shortcut to changing it or do i have to take the diff out and split it apart? Thanks.

[wheeler73]

Yes unfortunatly you have take it out and split it. If you are looking to almost loack the diff use plumbers silicone paste. Its cheap and avaiable at any hardware store and it works great.

[motoracer58]

oh ok maybe ill just do that then, hopefully i can return this fluid

[js4544x4]

you allready have the fluid. 50k is good. unless you dont want any give. what kinda driving do you do?

[texazbadboy]

i was thinking the same i've got 30 and 10 k witch one would be better where?

[motoracer58]

little bit of parking lots but most of its offroad, some grass but mostly dirt, right now its horrible, one legs in every turn. i want it pretty much locked, should i just use the 50k or will it still want to open up offroad?

[RedMan3]

whatever you do, dont lock it if you're mostly offroading... Use the 50k... If you lock it, youll be spinning out everytime you turn. Locking the diff is only for onroad purposes (typically for drag racing and straight line runs).

[ban-jato-runer]

go with the 50k. i do a little bit of every thing all the time and its great. i even drift with it and it has a good lock even for drifting.

[RC-Crazy]

I would go for 20 - 30k for off-road. 50k+ for on-road.

[js4544x4]

off road 50k keeps it from spinning one wheel pritty good. just fill the diff all the way.

[texazbadboy]

whats the best way to change the diff fluid?I've heard numerous ways to do it but dont know witch one works best.also i'm thinking of putting 1k in front and 3k in the rear.does anyone run this fluid combo?

[RedMan3]

What the heck are you talking about texazboy...

You just take out the diffs, open up the casing, unload the oil (just try as hard as you can to get the stuff out, you could boil it to thin out the oil), and then refill....

[jpoprock]

Are the diffs in the Jato any different than the Emaxx? I havent even looked at my diff yet. I plan to open them up to inspect, and will probl put fresh in soon. I will be driving my Jato on the street only. I read somewhere that 10k is good for the front. Is that true. I also have some 100k for my emaxx rear diff, and sone 50k. I locked and shimmed my Emaxx rear diff. as well as putting an Flm Alum cup in with 3mm screws.

Is it advised to shim the Jato diff, or installing an alum diff cup?

jpoprock,

- monster truck diffs and stadium trucks are different, but that shouldnt be a problem if you are a true RCist. just open it up, and have confidence because there are exploded views on this website

- No it is not necessary to shim the jato diff.

- No aluminum parts are necessary for the jato diff, it is fine the way it is designed

- Try thicker oil than 10k if you are running strictly on road. Try 30k-50k. Just dont lock it.

- With your emaxx, is normal to have thicker oil in the front diff and thicker in the rear. When the weight shifts to the rear wheels when accelerating, the front diff tends to unload due to less traction. Thicker diff in the front will lessen the aggressiveness of the front wheels, thus giving you more traction and control.

ok redman sorry were not all experts racers like you!i was trying to get some info on changing diff fluids because i've read dittrent threads on sealed and unsealed diffs so i wanted to make sure i didn't screw my diffs up!!!Some of us dont have the ability to just go buy new parts like it ain't nothing!I thought these threads were to help people not to try and make them feel stupid!Other people read these threads and might have the same question so be a little more considerate when you respond to these threads!!!!!!!!!!!!!!!!!!!!!!

[js4544x4]

the jatos diff takes fluid right. so its sealed.

[RedMan3]

I wasnt trying to make you feel stupid texazboy. But when you say, "front differential" and "jato" within a couple of sentences of eachother, it had me roll my eyes. Most people wouldnt have answered your question, they wouldve just told you to go to the emaxx forum.

ur jato has only one diff.....
so u leave us all askin the question... what r u talkin about....
i thought his response was very considerate.......... he at least took the time to ask for clarification on what meant.... it's more than anyone else has done so far ......

[texazbadboy]

I understand that and i should have specified that i had a t-maxx not a jato .When i did a search on diffs it listed this thread so i posted my question.I know this is a jato thread but may people in these threads have more than just jato's.I was hoping to get some insight from those guys.I apologize if i did make my self clear.I don't know alot about what the different Traxxas cars and which ones had multiple diffs.

[jpoprock]

Ok... I guess I too am confused. Being a first time Jato owner, and coming from a Maxx truck. I see that it only has one diff. My bad. Also, you say it takes fluid and is a sealed diff. So, to open it, do you literally have to CRACK open a case and reglue it or something? Or does it simply unscrew apart? And yer saying "fluid" is different than diff "silicone" that I use in my Emaxx. So, just what fluid do I buy then? 50K diff "fluid", or is it called something else?

Thanks!
Jason

[texazbadboy]

thank you jpoprock!!! now im getting somewhere!If one doesn't know what hes doin he can really screw things up!so if anyone read our questions please help!I've even posted on t-maxx threads and still dont get answers!

[RedMan3]

The jato has a diff where you unscrew a couple of screws on one side, and the one side comes off. Then you can unload the oil. And put in new oil.

You can put pretty much anything in a differential. But of course silicone oil is what is supposed to go in. Traxxas uses grease on some of their models, but silicone oil (like from ofna, sportwerks, etc) is definitely more consistent. And i have found it to be better for the diff.

To lock a differential, people have put jb weld to silly putty.

Again... exploded views are one of the best resources for your rc vehicles...

[texazbadboy]

so if you have sealed diffs like i do there isnt anything i need to do to keep my fluid in?

[RedMan3]

You just screw it back together.... thats it, nothing more, nothing less...

[jpoprock]

Ok, I get it. They are sealed diff's that screw together tightly. When you guys say stuff to a newbie, we take it literally. You said oil. I assumed OIL. Sure, silicon is oil I guess. But I would have said, "you put some silicon diff oil in it". Which is why I was questioning it. Common sense says that whatever goes in the Maxx diff's will go in the Jato diff, but who knows. This Jato is put together completely different than a Maxx veh for sure.

Exploded views are great and all. But when you need specific how to info, they don't always tell the tale. The exploded view for instance, shows the throttle spring on the throttle pully, but it doesn't show you just where the other end attaches to. It also shows that the diff in fact does screw together, but sealed to me means "can't open it"! Also, that is the funkiest looking diff set up I've ever seen. I'm not used to them looking like that to be honest! I picture more of a housing. But this diff sorta fits into the tranny, unlike the Emaxx.

Thanks!
