I disagree. What's the difference between crushing a new sleeve and crushing a used sleeve to the same dimension? I recently had one of mine apart to lube the bearings. I returned the lock nut to its original location, as I re-used the original bearings. The purpose of the sleeve is to establish a minimum distance between the inner races while still being able to make the retaining nut tight enough that it won't come loose. Without the sleeve, you couldn't do this- the bearings would be so tight they wouldn't turn.
