Official Erevo 1/8 scale center diff thread

Then I put the 8X12X3.5 bearing on the cap. Here you can see a shim underneath the bearing, you can do without it. I had the shim so I used it, it just positions the bearing in the middle of the output gear.



I assemble the diff with my choice of diff lube. I like to run 100k for a stiff diff. On 4S, this lube is thick enough to allow some wheelies but unloading to the front is minimal. 50k will give you a looser diff with more unloading to the front but on 4S wheelies are practically inexistent.



I slip on the Traxxas output gear over the posts and bearing.



Now for the carbon fiber disk to hold the gear in place with two M3X6 mm flathead screws.



The last part is one of the plastic spacers that come with the stock output gear and shaft of the ERBE. I sanded it down to the right length and it serves as a spacer so the CD can butt against the bearing in the tranny case.



I slipped it on the output shaft and in the carbon fiber disk until it is well seated against the cap and put a drop of CA glue to glue it to the carbon fiber disk.



Now install the CD in your ERBE and enjoy some trouble free CD action for racing. Next posts will be the Traxxas TRA3985X output gear installed on the scjrss and CowboyRay CDs.
