WARNING
Do not drain the transmission oil and do not allow grease or oil to get on any part of the clutch disc, pressure plate or flywheel surfaces.

  1. Remove the transmission from the car as previously detailed.
  2.  
  3. Loosen the set bolts one turn at a time until the spring tension is relieved.
  4.  
  5. Remove the set bolts and then pull off the clutch assembly.
  6.  
  7. Unfasten the release fork bearing clips. Withdraw the release bearing hub, complete with the release bearing.
  8.  
  9. Remove the tension spring from the clutch linkage.
  10.  
  11. Remove the release fork and support.
  12.  
  13. Punch matchmarks on the clutch cover and the pressure plate so that the pressure plate can be returned to its original position during installation.
  14.  


CAUTION
If the screws are released too fast, the clutch assembly will fly apart, causing possible injury or loss of parts.

  1. Slowly unfasten the screws which attach the retracting springs.
  2.  
  3. Separate the clutch cover and pressure plate from the clutch disc/spring assembly.
  4.  


CAUTION
The clutch driven disc may contain asbestos, which has been determined to be a cancer causing agent. Avoid inhaling any dust from any clutch surface! When cleaning clutch surfaces, use a commercially available brake cleaning fluid. Never clean clutch surfaces with compressed air.

  1. Inspect the parts for wear or deterioration. Replace parts as required.
  2.  
  3. Installation is performed in the reverse order of removal. Several points should be noted, however.
  4.  
    1. Be sure to align the matchmarks on the clutch cover and pressure plate which were made during disassembly.
    2.  
    3. Apply a thin coating of multi-purpose grease to the release bearing hub and release fork contact points. Pack the groove inside the clutch hub with multi-purpose grease.
    4.  
    5. Center the clutch disc by using a clutch pilot tool or an old input shaft. Insert the pilot into the end of the input shaft front bearing and bolt the clutch to the flywheel.
    6.  


Bolt the clutch assembly to the flywheel in two or three stages, evenly to 15-22 ft. lbs. (20-29 Nm).

  1. Adjust the clutch as outlined earlier in this section.
  2.
