FREE-PLAY



  1. Total clutch pedal free-play should be 3 / 4 -1 in. (19-25mm). The free-play is adjusted by means of a threaded rod which rides in the outer end of the throwout bearing arm.
  2.  
  3. To adjust the free-play, first remove the pedal return spring.
  4.  
  5. Loosen the locknut on the equalizer rod (the threaded rod).
  6.  
  7. Adjust the rod length by turning the rod. When the release bearing (throwout bearing) is just lightly resting on the fingers of the pressure plate, the adjustment should be just about right.
  8.  
  9. Check the clutch pedal free-play. There should be no more than 1 in. (25mm) of free-play before resistance is encountered. If there is too much free-play, the clutch will not engage fully. If there is too little, the pressure plate will ride against the clutch all the time and the clutch will wear out quickly.
  10.  
  11. Tighten the rod locknut and install the return spring.
