Ehh, what!! Top shaft 9601

We all know of the binding and that the planes for slipper are sometimes too deep onto the shaft....

This I never thought was possible. Check out the "thread" on this one.
It actually took me a fair while to understand why I couldn't get the nut on there..
Its no thread! It has no thread pitch

Haha yeah Ive seen that on a screw before too. Crazy stuff.

AE quality = poop
Recently I bought a new center gear diff kit for my 44.3, it all went together fine and dandy, but then the bearings wouldn't fit on it! I spend 15-20 minutes filing the damn thing, at the track, to get the bearings to fit. I sent AE an email complaining, in a civil way, about their poor quality.
At least in my case though I was able to fix it track side. No way to fix that POS you got there

I guess that isn't knurling but how do they cut threads with no slope? Seems that they would have to go out of their way to pull that off. Whuuf.

If I understand correctly it is because the threads are rolled- the dies were not set properly. So instead of rolling threads it rolled....lines

That definitely is something strange. I've had some machining experience with cutting threads and as far as I know the machines we use wouldn't even be able to mimic that process even if you screwed up on the machine settings. Seems like whatever bit they were using wasn't set correctly, I bet an entire batch went out like that. Just chalk it up to crappy Taiwan quality control, thats basically where all manufacturing is done these days.
