I can't recall for sure what size now (2mm think tho), but yes, it was very tight and had to be forced thru w/a hammer. It was a real bastard to get thru :)

I have a 8XL running on 4S and 5S. Lots of TQ. Slipper is kept pretty tight so it doesn't slip and heat up too much. Overall I'm not that hard on the truck tho.

Now wouldn't it be nice if they came with the mod....

Well, you know... we COULD just weld it. It would have to be a good weld, to maintain shaft balance. Maybe just two tacks on each side?

I finally put the hex over to the input shaft .
Boy it was hard to put into with a hammer there is no way it will get slip and out of that hole,for a while I thought it will not go inside,I file it first just like SSS did suggest and it finally went all the way in to the other side with a hammer. here is a pic

Here is mine that I did. Guess what happens when your pin is to large? :026:

I had to use my old gear after I broke the new one! :035:
But it turned out very well, it was a very, very tight fit. I had to stop hammering it, and use a large vice to force it in. It worked!

Oh, i forgot to mention, i used a drill bit end. I can't remember what size but i had to grind it down alot, the first one showed it wasn't ground down enough.:024:

So hopefully this stands up to my 7XL. The gear is actually to original gear from my first emaxx.... 6 years old! :005: Still looks as good as the new, only a little grime inside the gears.
