I bought two BBS02 48v 750w motors that weren't exactly the same. One fits into the frame easily, while the other doesn't. I fixed it by sanding off the color from the outer part (axis) of the motor (look at the picture), so it fits now.
Since there are instructions on Youtube, I assume I'm not the only one with this problem. I'm more interested in the material of this outer part (axis), is it iron or aluminium? What can I do so it won't rust?

I just checked, though I can't get to that actual part because it's installed, the back side of the gear housing seems to be ferrous and they look to be the same casting.
 
I checked with magnet, its iron. It's likely that grease will be the best solution.
 
Thanks. Today I have assembled BBS02 without any problems.

But what is with throtle? Only on off position ????
