4 AND 6-CYLINDER ENGINES
  1. Loosen the nut at the forward end of the clutch fork pushrod.
  2.  
  3. Using a wrench on the machined flat at the pedal end of the clutch fork pushrod, lengthen or shorten the rod in the swivel to allow 3 / 4 -1 in. free travel at the clutch pedal. Shortening the rod will increase free travel and vice versa.

  5. Hold the pushrod at its machined flat and tighten the locknut.

V8 ENGINES

This clutch linkage has a two section clutch fork pushrod.

  1. Loosen the locknut.
  2.

  4.  
  5. Torque the locknut to 8-12 ft lbs. Check the free travel at the clutch pedal, which should be 3 / 4 -1 1 / 8 in. for 1964-65 models, or 1-1 1 / 2 in. for 1966-67 models.

  1. Disconnect the return spring at the clutch fork.
  2.

  4.  
  5. Turn the pushrod three turns and tighten the locknut.
  6.  
  7. Install the return spring and check for the correct pedal free travel, which should be 1-1 1 / 8 in. for 1968-70 models, or 1-1 1 / 2 in. for 1971-72 models.
  8.  

V8 ENGINES

The adjustment is the same as for the 1968-71 4 and 6cylinder models, except that the V8 models have a two-section clutch fork pushrod. In this case, turn the adjusting rod section of the pushrod to obtain the correct clutch pedal free travel.

You can also use this procedure on any earlier models that have a gauge hole in the clutch pivot shaft arm.

  1. Disconnect the return spring at the clutch operating fork.
  2.  
  3. Use the linkage to push the clutch pedal up against its rubber bumper stop.
  4.  
  5. Push the end of the clutch operating fork to the rear until the release bearing can just be felt to contact the pressure plate fingers.
  6.  
  7. Detach the front end of the operating rod from the clutch pivot shaft arm and place it in the gauge hole on the arm.
  8.  
  9. Loosen the locknut and lengthen the rod just enough to take all the play out of the linkage. Tighten the locknut.
  10.  
  11. Replace the operating rod in its original location.
  12.  
  13. Replace the return spring and check the free-play at the pedal pad. It should be about 1 in. or more.
