What great info on diff fluid this is very informative on almost all of my redcat diffs that I have rebuilt they either have no difffluidor itsverythin like asaladdressing so please check your diff fluids to keep your diff running right. Great post.

I have 3 Earthquake 3.0's and me and my boys run them on a track withhard packed red clay with good traction.What's the recommendation for this type vehicle in these conditions. I experience pretty hard push in the corners right now and would like to loosen up the rear just a little. Also the steering under excelleration is very hard to control. I've tried to reduce the over steering by reducing the steering travel on the transmitter but still must be very very smooth with throttle control or the front end wants to dart right or left. Pretty dissapointed that Redcat would install these diffs dry but now that I know I would like to learn to tune these to my favor. Thanks for the help. I love learning new secrets of speed and control on these trucks.

Well i race on hard pack red clay with great traction I found that 3,000 in the front 10,000 in the center and 7,000 in the rear has worked best for me in the diffs. I think that this can change with the type of driving style everybody driving style is different.

Cool! thanks for the recommendations. Looks like I will be headed to the LHS tomorrow and pick up some oil. I'm getting the trucks ready to get some track time this coming week so it will be great to see the difference in performance. I also just found a good article on a website called www.rc411.com regarding diff oils so I'll do some studying tonight.
Merry Christmas!!

Your welcome thats great.

I am running in my Backdraft 8e (loose track) 5000 front 7000 center 3000 rear but It may change that is had had when I opened the diffs. Better then nothing......

How full should the diffs be? Thanks in advance.

RE: Diff fluids Just the basics
 

They should be full all the way up with just a lil room left to tighten your screws down without any fluid leaking out. But the diffs should be full.

Earthquake 8e pretty dry from the factory

RE: Diff fluids Just the basics
 

That seems to be the norm but its not a good thing. The teeth needs to be good andlubrication.

RE: Diff fluids Just the basics
 

Any experience with the 8e and what fluid for all around use? No racinf just bashing pretty much. Thanks

whats going to be tighter 3000 or 10000? want my sons volcano epx to have more positive traction in rear. he likes wheelies and dougnuts.

RE: Diff fluids Just the basics
 

If he is just going to be bashing just fill the diffs with grease. ie auto wheel bearing grease it is messy but it should do the trick.

RE: Diff fluids Just the basics
 

I know to fill rear full to top. But do I fill front to top or just halfway?

RE: Diff fluids Just the basics
 

fill'er up!!

RE: Diff fluids Just the basics
 

Thanks

RE: Diff fluids Just the basics
 

do you have to tear apart the whole truck just to fill diffs? looks like bumpers atleast and maybe more. http://www.redcatracing.com/site/par...canoepxpro.jpg

any one got pics or video of this? since i went to 8.5t brushless on this truck it has bad one wheel peel.

RE: Diff fluids Just the basics
 

I don't know about that truck I have a few vids on working on the diffs on an Earthquake though don't think that would help. Just start unscrewing until you get there just take pics (so you can put back togther)and take your time.

RE: Diff fluids Just the basics
 

@ derek when you say filled with grease how much should be in there ?

RE: Diff fluids Just the basics
 

this should be a sticky! why isnt this a sticky? sticky it now!!

RE: Diff fluids Just the basics
 

You can fill with grease just about until it covers the gears not all the wayup tothe top. just gets messy when you put back together. If your bashing you may want to go with a marine grease better then auto bearing grease.
what type of surface are you going to be running on? have you pulled them apart yet?

RE: Diff fluids Just the basics
 

the diff was empty and burned the bearing through the case im waiting for the new diff but im going check them all and is that regular marine grease thanks for the info

RE: Diff fluids Just the basics
 

If your bashing or some track use or if its a 2wd then marine grease it is....... I have used it but now all my stuff is track duty only so I only run diff fluid.
