  Q: How to remove the transmission (or transaxle), clutch, Flywheel, and Flywheel Ring Gear on manual transmission cars on Mitsubishi Cordia?

  A:

  To remove the transmission or transaxle, and the clutch on manual transmission cars, first take out the flywheel and ring gear on manual transmission vehicles or the flexible drive plate on automatic transmission vehicles by removing the six large flywheel bolts from the rear crankshaft flange. The flywheel or drive plate along with two mounting rings can then be removed. For automatic transmission cars, the Station and '83 Cordia and Tredia utilize a flexible drive plate that bolts to the torque converter and includes the ring gear as an integral part, while the '84 and later Cordia and Tredia and the Galant have a flexible drive plate that bolts to the torque converter but does not include the ring gear. If the converter-mounted ring gear needs replacement, the entire converter assembly must be replaced by a specialized shop. Inspect the drive plate for cracks, distortion, or severely worn or broken teeth, replacing it if necessary, and check the flywheel for cracks, ridges, or burn marks, ensuring the surface is true with a dial indicator, where runout must not exceed.005 in. Most flywheel issues arise from excessive clutch slippage, so if the clutch has been abused or worn, the flywheel's condition should be questioned. If the ring gear is worn or broken, the flywheel assembly should be taken to a machine shop for ring gear replacement, which requires high-temperature installation. Additionally, check the starter pinion for damage if the ring gear is compromised. When checking the flywheel during clutch repair at high mileage, replace the pilot bearing for the transmission input shaft located in the center of the flywheel. For installation, place the flywheel or drive plate and mounting rings on either side, then torque the bolts in stages to 94-101 ft. lbs., followed by reinstalling the transmission or transaxle along with the clutch.

  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.
