My e-revo brushless edition build

I ordered the kershaw center dogbones and will have to do what you did to make them fit with the rcmonster cups on the diffs I guess.

So a regular drill bit will put a hole through the revo tranny output shaft? Did you have to do that for both sides?

I'm going to use one of the kershaw cups clamped in my drill press as a guide for the bit so hopefully that will keep it centered on the shaft and help with starting the hole.


thanks for the help!

I didnt drill any holes in my shaft`s to fit the kershaw`s.. I just moved the tranny 1-2mm backwards.. 3 minutes with the dremel fixed that :)
The rear center axle actually was a bit short, not too short, but short enough to move the tranny 1-2mm.. Now both sits perfect, deep into the cups.

Well, I got the kershaw axles today and got those installed so at this point I basicly just have to put the truck back together and I should be good to go

The longer rear dogbone fit fine but I did have to drill a new pin hole on the front tranny output and cut off about a 1/4 inch of it but thats all it took...I now have about 1/4 inch of play on front and rear dogbones which I think is enough to prevent any binding when the chassis flex's...besides most of the flexing it does actually opens up the gap rather than closing it so it should be fine.

I put a few o rings under the ends of the dogbones on each side to keep them centered and prevent them from sliding back and forth all the time....Any reason that may not be a good idea? They can still move back and forth, just not without a little pressure.

Is it normal for these lst diffs to be a little notchy when new? (I mean the ring and pinion, not the diff itself) One is fairly smooth but the other is pretty notchy, I assume they will wear in and I don't see any way to adjust the mesh aside from the one shim on each one and thats already on the side that opens up the mesh slightly.


heres a pic of where I'm at

Thats odd, Mine was too tight in front for that to work and the rear one would have been to tight if I moved the tranny rearward any. I did notice that the front dogbone ball had been ground down flat after the black finish was applied so I guess kershaw thought they are just a little too long too.
