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?
