wondering if the differential on the jato 3.3 needs to be lubed, i see in the parts list it comes with there are like 5 different weights of oil , odd but when i took apart the diff there was no grease or oil in it, basically is it an oil free truck or what? and ill mention ive run about a gallon through it and have had no problems just wondering strictly for a maintenance basis

IHave a Jato 3.3 and the diff does have diff fluid in it. It comes stock with 30wt I run 70wt in mines.

hmmmmm i must be out of my mind then, i couldnt find anywhere to drain the diff or anything, where do you put fluid in, how often do you change it out?

pubmaster861

ok if there is diff fluid on the jato where do i put it in? i have just taken my jato rear end off, whole rear assembly off the main chassis, and looking at gars turning as i rotate the tires, isnt there supposed to be fluid in there?

pubmaster861

so basically i want to know how to check the fluid , where it is

quietnas1

Ok there really is no place to drain the fluid from. When you remove the diff it has 4 small screws in it. When you remove those 4 screws the diff cover will open and you will be able to see the spider gears and the fluid in the diff. If there is no fluid the seal probably went bad and it leaked out. Im gonna try and send you a link with an exploded view.

ok i understand how it all goes together, but in a way isnt the diff more in the transmission then?, cuz ive taken apart the rear end that drives the drive shafts, like the gears in that area, i think your tryin to say its in front of this part right? sorry if thats confusing, basicaly to take it apart and see the fluid would i need to take the brake assembly off?

quietnas1

NO. The diff is where the drive shafts go connected to. That gear has 4 screws and it opens up.

pubmaster861

wow thats not good, i opened up that whole area and it was bone dry? , what do i do? how do i add oil to it?

quietnas1

Ok here is the link that shows the diff http://www.traxxas.com/PDF-Library/5...509_tranny.pdf. Im gonna send a pic of it also but look at the pdf file so you can get a good understanding of the transmission and the diff.

quietnas1

ok here is a pic of the PDF file.

pubmaster861

ok i understand where it is and how it goes together but how do i add fluid?

quietnas1

You have to remove the 4 screws that hold it together and then add fluid to it.

Hi guys, I've got an important question that I need answering A.S.A.P that I've posted in the Official Traxxas Jato 3.3 Thread

Please read it

Thanks

when you say 30wt, do you mean 3000 or 30000? or 30? I thought 30 or 300 was only used for shocks...

quietnas1

I mean 30. Now the Jato comes stock with 30wt diff fluid. I actually use 70wt shock oil in the diff and it works great and gives excelent traction. Im actually thinking now of using Mobil 1 grease in the diff to lock it.
