Fig. Fig. 7: Apply suitable grease to the pilot hole before installing the clutch and transmission

  1. Remove the mounting bolts, clutch, and drive plate. Coat the splines of the transmission input shaft with Molykote® Long-term 2, Microlube® GL 2611, or equivalent grease. Make sure the clutch pilot bearing, located in the center of the crankshaft, turns easily.
  2.  
  3. Check the clutch disc for excessive wear or cracks. Check the integral torsional dampening springs used with lighter flywheels, for a tight fit so they cannot rattle or become dislocated. Inspect all rivets to make sure they are tight. Check the flywheel to make sure it is not scored or cracked. Use a straight edge to make sure the contact surface is true. Replace any defective parts.
  4.  

To install:
  1. Fit the new clutch plate and disc in place and install the mounting bolts.
  2.  
  3. When installing the clutch retaining bolts turn them gradually in a crisscross pattern to evenly tighten the clutch disc and prevent warpage.
  4.  
  5. Install the transmission and the clutch housing.
  6.  
  7. On vehicles equipped, install the speed and reference mark sensors. Install the protective heat shield.
  8.  
  9. Note that on late model 6-cylinder engines, the clutch pressure plate must fit over dowel pins. Tighten the clutch mounting bolts to 16-17 ft. lbs. (21-22 Nm) for 1970-82 vehicles, and 17-19 ft. lbs. (22-23 Nm) for 1983-88 models.
