Yes the collar gets crushed which reduces the end play but; unfortunately, it is a one-way action, once the collar is crushed it cannot be "uncrushed" so if it is too tight you must start over with a new crush collar. The key is to tighten the assembly in very small increments/bumps. On a clean and re-pack, re-using bearings if you can, there shouldn't be a need to crush the collar just put everything back to exactly where it was.

Consider using correct thread locking compounds wherever possible and/or needed.

If you need new bearings the chances of being able to re-use the collar go down but you cannot tell until it is assembled.

Good luck!!!
