My 326 has the wobbly 30 minute hand and its annoying. Can this be rectified, and if so how

I have a problem will the small chronograph minute hand it seems loose when you move the watch the hand moves about 1 minute. It seems tight on the pin, and works perfectly when the chrono is activated. Is there something I can do to rectify this. The movement is in the Pam326m Daylight. Is there a dissassembly guide for this movement anywhere? Thanks
