how to adjust clutch from inside???

yea i was gonna take it to a shop but i dont trust mechanics theyl lie and say i need a new clutch or sum sh*t. no offense to the builders here i just had a lotta bad experience with them whether it be cars or quads
 
is it possible to loose the ball without having the shaft disassembled? i've just got the rod threaded almost clear off the nut.

Idk I think when u loosen the shaft the ball is loose also. Then that's when u adjust it with the actuator I guess. or splitting the case? I'm not sure I've never been that far into a motor. I'm going by wat I read
