Removing lens mount FD

Fellow Photographers: I Have the Canon FD 500mm f8 Reflex lens. My

question is that when you rotate the lens in to the lock position

there is quite a bit of play in the back and forth movement, I have

been told that this is acceptable, but when you remove the drop in

filter you can see the lock mechanism, when you rotate the lock part

you can see the very small screws move up and down does any body

have the same lens like this or can I remove the back of the mount

and tighten up the screws my self, and if possible how do you take

of the back mount. Appreciate any help as the lens has had very

little use.

Kind regards. Mike.
