It is necessary to adjust your clutch cable free play from time to time. This Air Cooled VW Clutch Cable Wing Nut is on the threaded end of the clutch cable, making it easy to adjust by hand. Sometimes you will need a pair of vice grips to keep the cable from spinning while you adjust the tension. The cable and nut are commonly rusted so you might use some penetrating fluid to help the job go smoother. Refer to the Official VW Service manual for your particular year for proper adjustment.
