I had my frame and swing arm powder coated. Now after installing new bearings and torquing the swing arm, it's very stiff (not moving freely). I think the problem is that the flange the dust seal sits on is now a larger diameter (seems like the dust seal is supposed to rotate with the swing arm).

Do you think it is necessary to sand off the powder coating on that flange, or do you think it will just wear in after some use?

Pictures attached, I hope my description is clear.

Yes, all the bolt threads and bearing journal/seats were not coated, it's just the outside of this flange causing the dust seal to fit tightly. I used a lot of grease, but I may just sand the coating off, or maybe sand the dust seal. I'm worried about the friction heat during use might completely destroy the dust seal.

Thanks
