Flywheel or Flexplate & Ring Gear


Removal & Installation

The most common reason to replace the flexplate is broken teeth on the starter ring gear. On automatic transaxle vehicles, the torque converter actually forms part of the flywheel. It is bolted to a thin flexplate which, in turn, is bolted to the crankshaft. The flexplate also serves as the ring gear with which the starter pinion engages in engine cranking. The flexplate 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 flexplate are separated, so the converter and transaxle can be removed together.

  1. Remove the transaxle from the vehicle.
  3. Support the flywheel in a secure manner.
  5. Matchmark the flywheel/flexplate to the rear flange of the crankshaft.

  7. Remove the attaching bolts and pull the flywheel/flexplate from the crankshaft.

To install:

  1. Clean the flywheel/flexplate attaching bolts, the flywheel/flexplate and the rear crankshaft mounting flange.
  3. Position the flywheel/flexplate onto the crankshaft flange so that the matchmarks align.
  5. Coat the threads of the attaching bolts with Loctite® Thread Locker 271, or equivalent, to help ensure that the attaching bolts will not work loose. Install the bolts finger-tight.
  7. Tighten the attaching bolts in a crisscross fashion in 3 even steps to 70 ft. lbs. (95 Nm).
  9. Install the transaxle.
