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

So I am not the only one who takes forever to rebuild a diff. I always want it running as smoothly as possible and end up taking it apart and reassembling a dozen times or more before I am happy.

I feel it is the only way to get it right. I would rather be quick at getting the diff in and out, and then take my time to build it just right. That way it will run properly for a while, and not require disassembly again. We spin these small gears at stupid fast rpm, and they are not really that strong, proper assembly goes a long way to making them last!

These tips in this thread saved me alot of time because the first time I went to service my diffs I took apart the whole rear bulkhead.Today it took about 1 hour to take the diff out swap the diff cup out for a alloy cup then back in.Thanks!!!!!!!!!!!!!!!!!!

Indeed. I sold my E-Revo with a stripped rear diff because I didn't want to spend 1-2 hours pulling it apart, putting in the new diff, shimming the new diff, then putting it all back together. After all my Revo put me through I said screw it and just sold it. Now I have a Muggy with diffs that take 30 seconds to get to but I never need to get to them

Whats the best diff cup and outer diff housing available that doesnt bind.I made the mistake buying RD Logics cups and housings and the housings bind and the bearings dont fit the case.I tried shimming,stock diff cups evrything I could think of and they still bind when you tighten the outer case.

Mikes Hybrid's...

[phatmonk]

Thanks are they compatible with the Slayer center drive shafts.Can I just buy the cases?Will they work with the stock Revo/Slayer diff cups?

[lincpimp]

The hybrid diffs use 1/8 scale internals. They are pricey, but will most likely outlast the truck. They are the strongest option for the revo so far.

Well I finaly got the funds to upgrade my Slayer diffs.I went with the Integy hardened gears and RC-logics cups and Integy outer cases.The outer cases came with shims.Everything fit together very well with no bindingin the diff themselves allthough.I had to shave a bit of the Traxxas plastic drive shaft on 1 side of the truck so it wouldnt bind on the Integy case.Besides that the diffs are very smooth.For about 100 bucks so far its worth it.The ring gear is spiral cut and very presise along with the pinion.The Traxxas stock diff both were originaly assembled either too tight or too loose 1 of the ring gears had a screw coming loose from the cup.VERY POOR ASSEMBLY QC.

Well I thought I'd revive this cause I just tore out my front diff, cleaned out all the grease, washed, dryed, filled with silicone, and reinstalled it. It took me exactly 10 minutes to get the diff out, apart, and soaking. I spent 35 minutes cleaning and re-assembling, which is gonna happen no matter what diff your talking about. It then took me about 15 minutes to get it all back together, funny that it's harder to get back together, getting the center shaft lined back up is a PITA for the front cause it's so damn small.

The revo diffs are not that hard to get to but no where near as easy as a lst. Th elst was the easiest to get too. My savage was the hardest and before the X the savage had tons of diff issues. Thats why I sold mine!!!

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

[madmaxx]

i just built a couple diff's using the RRP ring & pinion along with Emaxx spyder gear's and RD logic's inner/outer case's but have'nt had a chance to run them as of yet, i did have to shim them up to get them nice and smooth

[E-fanatic]

Let me know how they do! How did they look compaired to the stock gears? Are they smooth?

IMO i don't think i'll be having any issues with my diff's

the stock gear's are slightly darker and shiny in appearance where as the RRP are more of a dull, matte finish

like butter!

like to hear that. I might have to pick up a few sets
