Diff fluid for Jato
 

I just tore my jato down for cleaning and I wanted to see what diff fluids work in this truck. I really havent gottne to drive in the dirt yet, but even still this thing is all over the place even on pavement. I heard a thicker diff fluid could possibly help with some of the spinning out problems, but I havent really heard exactly what to use in it.

RE: Diff fluid for Jato
 

you use shock oil it comes with 30wt in it allready use a lighter oil i use 20 or 25wt depending on track conditions the thicker the oil the more posi affect it has

RE: Diff fluid for Jato
 

You don't use shock you you buy diff oil, the rest i can't help you with.

RE: Diff fluid for Jato
 

this jato use's freakin oil in the diff? omg i just slap some chasis grease into my rusty's diff, and for the past 5 years, i havent had any problems

RE: Diff fluid for Jato
 

its a tunable diff like a 1/8th buggy but yeh i agree, just whack some random grease u got lying around in there.

I want as close to posi as I can get, so go with the thickest possible right?

RE: Diff fluid for Jato
 

posi?

NO it does not have oil in it. These people posting this don't have a clue. They assume everything. Jato's differential is shipped with Lithium grease packed in it. NOTHING else.

RE: Diff fluid for Jato
 

they are not shipped with grease they do have 30wt shock oil in them they are sealed and yes thicker oil will give it a more posi affect

RE: Diff fluid for Jato
 

Thank you brother, I can see what the mods were talking about, just dont go and listen to anyone.

RE: Diff fluid for Jato
 

thicker oil will cause the car to hook up more but locking the diff will make the tires balloon out (unload) lots of r/c's have grease in them from the factory but i always put diff silicone in them after cleaning the grease out. you just have to make sure the diff will hold the silicone? ive never heard of shock oil being in any diff..... it wouldnt last but 1 run, it will break down too fast.


in my LSP trug guys were having the prob w/ tires unloading cause they were putting 30,000wt , diff oil in theirs. i put 7000 wt. and mine was perfect

RE: Diff fluid for Jato
 

i use diff oil 5000wt,3000wt,1000wt depending on surface conditions in my Hyper7 and jammin but this truck uses 30wt shock oil in the sealed diff we are talking about a 2wd 1/10 truck the setup is different than in my buggys or my revo

RE: Diff fluid for Jato
 

I am having the issue with ONE tire unloading, and is really a pain. Its weird with this truckyou dont give it enough gas it wont move give to much and one tire rips loose and it flips itself over. I have been driving mosly on grass and pavement mind you and dont have much dirt or a track to run on till spring time. But I think if it has a more posi affect I will be able to control it a little better.

RE: Diff fluid for Jato
 

LOL sorry dude but every Jato sold has NO oil in the diff. It's even stated in the Manual. If you owned one you'd know this. First of all the diff isn't even sealed. So it'd leak like crazy. Also you remove the rear diff cover to remove the stock rear battery box. I'll scan the manal later for the tards who claim it has diff oil. Also tear my diff apart to show you there's no oil.

RE: Diff fluid for Jato
 

I run 50K diff oil in my Jato. I do not have too much of a leakage problem, but it will some. It has really helped my Jato hook up the track. Though now that I have added the Traxxas CVDs I may go down to a 30K. Yes I know those are big numbers, but that is what has been working. Read through the "official" jato thread and some of the race thread and this is what others are doing too.

Just for referance in my TTR S3 I run 5-5-1 ... but the TTR likes really light oils.

RE: Diff fluid for Jato
 

i must have bought the only jato`s with a sealed diff and 30wt and if you can look on page 44 Jato manual you might want to read the section,Tuning The Sealed Gear Differential,and next column From the factory,the differential is filled with SAE 30W viscosity silicone shock oil.Use only shock oil in the differential

RE: Diff fluid for Jato
 

My jato did have fluid in it when I changed it out for the 50K wt. But some must have leaked out or something in between then and when I added the CVDs because it did not have near as much in it as when I filled it... But I have never seen any signs of leekage... Just figured it happened at some point.

RE: Diff fluid for Jato
 

you need to take your diff apart and if it don't have oil in it, you need to put oil in it or you'll burn it up. Personally i run 50,000 wt in mine and it feels like a ball diff when properly built and handles very good to.

RE: Diff fluid for Jato
 

Page 44 in the jato manual, just as 52zmaster2001 said, in bold letters at the bottom left corner of the page. Tuning the sealed gear differential. And on the other side of the page it says just as someone else said above, from the factory the diff is filled with sae 30w silicone shock oil. I'm not saying anyones wrong but some of us are correct. Although when I opened up my diff there was nothing in it either, so maybe its a problem from the factory, and I have never noticed a leak anywhere and the truck has about 12 tanks of fuel through it, so I think I would have noticed a leak.

I should have just read the damn manual instead of starting a war. But I ordered 30k and 50k, I am also going to be doing the diffs on my lst2. So I will try both of them out and see whats up with it.

Thanks guys, Happy New Year!

RE: Diff fluid for Jato
 

I guess that will work in your jato then, but your lst2 will need real diff oil it has to much power to work with shock oil.

RE: Diff fluid for Jato
 

thicker oil=grease
thank you very much

RE: Diff fluid for Jato
 

No I did buy the diff fluid, I'm not going to bother with the shock oil, I ordered 30,000wt and 50,000wt from ofna and I also purchased the $10 little thing of "diff grease".

I was going to try the shock oil, but why even mess around, I'd have to take the diff completely out again if I didnt like it. So I'll start with the 30 and if that doesnt work I'll try the 50. As for my LST2 I am going to run 50 in the front and rear. I might wait until I can get out on a track to see the difference though with the LST2, no sense in putting the extra strain on it if I'm only going to be bashing it until it gets a little warmer out.

RE: Diff fluid for Jato
 

Excuse me, but my Jato did indeed have fluid in its diff. I know because the first thing I do when I get a RTR is go through it. Maybe I got a bad one? :eek: And it is indeed sealed, with a silicone gasket and x-rings on the outdrives.

Direct from the Traxxas site:

If you want I can even post up some pics of my Jato's diff torn down for your pleasure..

RE: Diff fluid for Jato
 

You could use grease in the diff, but most diff grease has the same effect as 10k silicone diff oil. I don't own a Jato, but I do have to tune my Mammoth ST diffs with diff oil. It seems like 30-40k oil would be a good starting point on the Jato. Oh, and don't worry about Badz, he just has this thing where everything anyone else says is stupid and his opinions are always facts. [&o]
