Removal Procedure


    Object Number: 895511  Size: SH
  1. Remove the transaxle from the vehicle. Refer to Transmission Replacement .
  2. Check the slave cylinder release bearing minimal bearing drag. Replace the slave cylinder if no/little drag is found.
  3. Notice: Remove bolts in a progressive crisscross pattern to prevent warping of the cover stamping.

  4. Remove the pressure plate assembly to flywheel bolts.
  5. Remove the pressure plate assembly and the clutch disc.

  6. Object Number: 897701  Size: SH

    Important: Black random spotting on the friction surface of the pressure plate assembly is normal.

  7. Inspect the pressure plate assembly surface for excessive wear, chatter marks, cracks, or overheating, indicated by blue discoloration. Replace the pressure plate assembly if damaged.
  8. Check for clutch cover assembly warpage using a straight edge and feeler gage.
  9. Specifications
    Maximum warpage is 0.15 mm (0.006 in).


    Object Number: 895528  Size: SH
  10. Check the clutch disc facings for oil or burnt spots. Replace the clutch disc if necessary.
  11. Check the disc for loose damper springs, hub, or rivets. Replace the disc if any are broken or excessively loose.

  21. If the flywheel is being replaced, remove and discard the flywheel-to-crankshaft bolts and remove the flywheel.

Installation Procedure

    Notice: The flywheel and flex plate bolts are not interchangeable. Ensure that flywheel bolts are used or a powertrain failure may occur.

  1. Install and hand start the new flywheel-to-crankshaft bolts.
  2. Tighten the bolts in a crisscross pattern.
  3. Tighten
    Tighten the flywheel-to-crankshaft bolts to 53 N·m (39 lb ft) + 25°.


    Object Number: 895511  Size: SH
  4. Install the clutch disc and pressure plate assembly to flywheel and loosely install the pressure plate bolts.

  5. Object Number: 895467  Size: SH
  6. Install the J 43482 in the clutch disc and push in until it bottoms out in the crankshaft.
  7. Notice: When tightening the pressure plate assembly bolts, do not tighten any one bolt more than half a turn at a time or the pressure plate assembly may warp.

  8. Tighten the bolts using a progressive crisscross pattern to prevent warping of the pressure plate assembly.
  9. Tighten
    Tighten the pressure plate-to-flywheel bolts to 15 N·m (11 lb ft).

  10. Remove the clutch alignment arbor from the clutch disc.
  11. Notice: Excessive amounts of grease on the input shaft splines can contaminate the clutch disc and cause clutch shudder.

  12. Lightly lube the input shaft splines with clutch spline lubricant P/N 21005995 or equivalent.
