  12. On 4WD vehicles, remove the driveshaft and the intermediate shaft. Remove the cable bracket and the side transaxle mount from the transaxle housing and body.



  13. Install a bolt at the cylinder head and attach a suitable chain hoist to the bolt and the other end to the engine hanger plate. Lift the engine slightly to unload the mounts or place a suitable transaxle jack under the transaxle and raise it just enough to take the weights off of the mounts.



  14. Remove the front transaxle mounting bolts. Remove the rear transaxle mounting bolts. Remove the side transaxle mount. Remove the five remaining transaxle mounting bolts and pull the transaxle assembly far enough away from the engine to clear the 14mm dowel pins.

To install:




  1. Make sure the two 14mm dowel pins are installed in the clutch housing.

  1. Disconnect the negative battery cable. Raise and safely support the vehicle, refer to the procedures found earlier in this section. Remove the transaxle from the vehicle. Matchmark the flywheel and clutch for reassembly.



  2. Hold the flywheel ring gear with a tool made for this purpose or an equivalent method of holding the flywheel. Remove the retaining bolts and remove the pressure plate and clutch disc. Remove the bolts two turns at a time working in a crisscross pattern, to prevent warping the pressure plate.

  2. Check the release bearing for excessive play by spinning it by hand. Do not wash with solvent as it is packed with grease. Replace if there is excessive play.


To install:




  1. If the flywheel was removed, make sure the flywheel and crankshaft mating surfaces are clean. Align the hole in the flywheel with the crankshaft dowel pin and install the flywheel bolts finger tight. Install the ring gear holder and tighten the flywheel bolts in a crisscross pattern. Tighten the flywheel bolts to 87 ft. lbs. (120 Nm).

  1. Install the clutch disc and pressure plate by aligning the dowels on the flywheel with the dowel holes in the pressure plate. If the same pressure plate is being installed that was removed, align the marks that were made during the removal procedure. Install the pressure plate bolts finger tight.



  2. Insert a suitable clutch disc alignment tool into the splined hole in the clutch disc. Tighten the pressure plate bolts in a crisscross pattern two turns at a time to prevent warping the pressure plate. The final torque should be 20 ft. lbs. (26 Nm).

  1. Remove the alignment tool and ring gear holder.



  2. If the release bearing was removed, replace it in the reverse order of the removal procedure. Place a light coat of molybdenum disulfide grease on the inside diameter of the bearing prior to installation.

  4. Adjust the clutch pedal free-play and connect the negative battery cable.
