Superwinch service

Hi is there anyone on here who services or has serviced a husky superwinch ew8. Basically the gear leaver is very sloppy. So iv checked the manual and parts list to see if it could be something broken. It only shows a spring and ball holding the pin in. So I took it apart to see if it was there. It is! But there's another hole which looks like there should be another!?! Just need to know if there is 2 or just one as it says in manual? Any help would be muchly appreciated.
