It would help to know what your aircraft is,and if you have a manual for it,detailing `HOW`.
You should have or make small clamps to hold the ailerons level with the wing surface ,and a method of holding the stick absolutely central.The bellcranks should have rigging pins to hold them at datum.
Its then a matter of measuring all similar pushrods/turns ,equal both sides,and then adjusting the cables equally,but not tensioned fully..Then check ailerons for travel/equal,rinse,check adjust a/rqd.finally,ok tension cables,check,check..or,get a proper `gingerbeer to do it whilst you watch.....simples....
Whatever you do to one pushrod will require other(s) to be adjusted,and the `other side`....Keep note of each adjust ment,ie 1 turn IN/OUT...
