Accessing E-Revo diffs - is it really that hard?

Has anyone see or used the rrp diff pinion and ring gears? I was looking at getting those and an aluminum diff cup when my diffs go! Any insite would be welcomed

My understanding is that its not so much the gears themselves as it is the cup and the diff housing. My stock gears have held up great since I replaced the cups and housing.

What is your take on accessing the diff's in the Savage X design (and also referring to the new brushless one)? I ask because I have one on order, but I'm second guessing myself on it - those 8ight-T's are looking awful nice, especially since the price on the 1.0's have dropped so much.

I will be ordering a savage flux. The new design of the x is much easier to work on everything! Also the diffs are better( and better than the ones for the e-revo) The only issue I have seen with the savageX diffs is that they dont come shimmed and they need to be! Once thats done they are golden! The new diff cup for the savage diffs is nice too!

I know the flux will still handle like a savage but it has a more durable drivetrain than the e-revo.

Well that is a classic truggy vs monster truck choice. I prefer monster trucks over truggies... But I am a basher and cannot appreciate the benefits of a truggy

X diffs are definately easier to get to. Shimming the diff is a must with a savage. Does the flux come with the al cups with the steel inserts? Those are mandatory in my opinion, I have tried all of the options for my savage and they seem to work the best. Plastic cups are just junk.

I have had great success with the erevo drivetrain, but you are most likely correct that the flux will be stronger. Now if only Losi would come out with an electric lst... That would put the erevo and flux to shame (as long as it had the mmm and motor in it)

My lst2 conversion was my favorit truck. The lst is a beast. IF LOSI MAKE A ELECTRIC MT I WILL HAVE ONE FOR SURE!

I'm in the same boat Linc. The tracks around me are just to damn far away to get to, and even then I'm not certain that I would enjoy it as much as bashing. I've already got that Hellfire truggy that I still need to finish anyway, so my "sensible" side tells me to stick with it instead of getting the Losi. But then, a clean looking LST2 showed up on Craigslist today, for a decent price (275). I think I will leave my FLUX order alone - it will be my first ever brand new RC. Kinda looking forward to that.

From what I could tell by looking at the spec sheets, they dont say how the diffs are constructed, but I'm assuming its the same as whatever the X has. Guess some of those questions will have to wait for delivery.

IIRC, the Revo diffs weren't that bad to get to. Remove the bottom skidplate and steering stop, unhook the outdrives from the axles, unhook one side of one shock, and remove the few top screws and one side of the bulkhead came off. Then, just pull the diff out. I may have missed a step, but it only took me a couple minutes to take one out.

[E-fanatic]

Dang, I blew another diff today The cup slit down the side. I guess I will be ordering an aluminum cup sooner than I thought. This is upsetting b/c the diff is only a few weeks old . I have my slipper set so I will not wheely from a stand still(and punch control set on the mmm at 70%) I guess the losi superbolt-on tires offer to much grip for the diffs to handle. I might have to go to the badlands(they just dont handle as well as the losi tires do, oh well)

Forgot to add: I had the diff out in about 3 mins! Im starting to get good at it

What weight diff fluids are standard front, center and rear for the e-revo?

[E-fanatic]

The front and rear come stock with 30,000 and there is no center diff. The traxxas optional center diff comes with 500,000. I have my front and rear set with 50,000

Please explain why the thicker flui

[E-fanatic]

The 30,000 that comes stock doest offer much resistance and feels like there is nothing in them(like an open diff) the 50,000 helps alot. I see that you have a few losis and I know they only use up to 10,000W in the diffs and that feels very stiff. The traxxas diffs need such heavy weight b/c of its design (has less gears in them than a 1/8th diff does, so the oil has to work harder to slow them down) Thats why the heavier fluid

IIRC front + rear's come with 30k as mentioned but the c/d come's with 100k stock, not nearly enough IMO....

i went to OFNA clear diff lock for the c/d and am running 30k in front and 50k in the rear

[E-fanatic]

Sorry, I was told by traxxas a while back that it was going to come with 500,000. I havent checked it since it was released

[E-Revonut]

As far as I know the Traxxas center diff comes with 100k. The stock diffs don't come with silicone fluid in them at all! They have nothing but some grease in them! I know that for a fact, I just took both mine apart last week and cleaned the grease out of them!

[E-fanatic]

Mine had silicone in mine. I switched it to 50,000. It helped alittle. I have bought 3 replacment diffs off ebay and they all had fluid.
