Warden,
There seems to be lots of info on this but do a search. The threads turn the normal way except to adjust you turn the center stud ccw or out not in like on US cars. I recommend backing off the locknut, turning the adjuster out 1/8-1/4turn at a time and see how it goes. Adjust only enough to take out the play. If you go to far you will cause excess wear in the box. RT
