  Q: How to remove and install the transaxle, Flywheel, and Flywheel Ring Gear on Mitsubishi Sigma?

  A:

  The procedures for removing and installing the transaxle are to remove the transaxle. For vehicles equipped with an automatic transaxle, remove the torque converter and examine the teeth of the ring gear. In vehicles fitted with a manual transaxle, match mark the pressure plate assembly and flywheel. Gradually loosen the pressure plate retaining bolts in a criss-cross pattern, supporting the assembly as the last bolt is removed. As the clutch disc contains asbestos, do not blow using compressed air or inhale the dust. Use with caution. Subsequently, mark the positions of the flywheel and crankshaft, loosen the retaining bolts in an even manner, and support the flywheel when you remove the last bolt. Check the flywheel or torque converter drive plate for wear or chipping and replace, if necessary. Check the starter drive if wear is evidence. As the flywheel is reassembled to the crankshaft, the retaining bolts should be installed finger tight first. The torque converter must be reinstalled on the transaxle. In diagonal patterns, tighten the flywheel bolt to torque specifications, and install the clutch and pressure plate assembly while replacing worn components. The torque converter must be replaced if the drive plate's ring gear teeth damage. This is because the ring gear is not separable. Damaged flywheel ring gear is generally more economical to replace the whole flywheel than just that part. To replace ring gear will involve removing the flywheel, tapping around the ring gear to loosen it, or if that does not work, drill hole between teeth in the ring gear to split it. Heat the new ring gear to 572 °F (300 °C) and place on the flywheel, lightly tapping if necessary. Let the assembly cool down in the air before reinstalling the flywheel and under the bolt specifications.
