Bicycle Hub Dust Seals

Replacement hub steel dust covers are generally not available as a spare part.

When they are damaged during removal, they can often be fixed by laying them flat side down on a sturdy bench (open side up); sitting the ball end of a ball peen hammer in the middle and giving that hammer a sturdy blow with a mallet (not with another hardened steel hammer - that's dangerous!). This will often open it up marginally and round out the rougher bits so it works OK.
