Removal & Installation



The flywheel on cars with manual transaxles serves as the forward clutch engagement surface. It also serves as the ring gear with which the starter pinion engages to crank the engine. The most common reasons to replace the flywheel are:



Broken teeth on the flywheel ring gear
 
Excessive driveline chatter when engaging the clutch
 
Excessive wear, scoring or cracking of the clutch surface
 

On cars with automatic transaxles, the torque converter actually forms part of the flywheel. It is bolted to a thin driveplate which, in turn, is bolted to the crankshaft. The driveplate also serves as the ring gear with which the starter pinion engages in engine cranking. The driveplate occasionally cracks; the teeth on the ring gear may also break, especially if the starter is often engaged while the pinion is still spinning. The torque converter and driveplate must be separated, and the converter and transaxle are be removed together.

  1. Remove the transaxle from the vehicle. For more information, refer to the Drive Train Section.
  2.  
  3. On vehicles equipped with a manual transaxle, remove the clutch assembly from the flywheel, as described in the Drive Train Section.

To install:

  1. Clean the flywheel/flexplate attaching bolts, the flywheel/flexplate and the rear crankshaft mounting flange.
  2.  
  3. Position the flywheel/flexplate onto the crankshaft flange so that the matchmarks align.
  4.  
  5. Torque the mounting bolts in a three step crisscross pattern, to the specifications shown in the Torque Specifications Chart at the end of this section.
  6.  
  7. On manual transaxle-equipped vehicles, install the clutch assembly. For more information, refer to the Drive Train Section.
