<p>I own a Gitzo GH2780QR ball head which is wobbly when the pan lock is unlocked. When locked it's fixed but a small gap appears. Inside the head there's a "locking disk" which is screwed to the head's base. See link for details (part nr. D4040.41):<br>

D3.0992) have to be retightened, but how to open the head in order to do this? Do I need special tools which only Gitzo has access to so I have to send it for repair, or can it be done with "normal" tools?</p><div></div>
