Lens mount on Nikon F4

  1. I have a Nikon F4. The autofocus drive mechanism would not stay out
    after pushing in the lens release button. I took the lens mount off
    of the camera (4 screws). Everything looked fine and I replaced back
    on. After pushing the lens release in and out a lot of times it is
    now working as it should. The camera had not been used in a while.
    Everything appears to be working correctly. The autofocus focuses
    like it should. My question is: By taking off the lens mount, does
    anything get out of alignment? Does the autofocus have to be re-
    aligned? I did not think about an alignment issue untill after I had
    removed it.There are no adjustments that can be made to the mount.
  2. Not that I have ever opened my F4, but many other cameras. I have never seen any shims anywhere making calibration possible so I'm sure the factories rely on well machined parts that can only be mounted the right way.
