To remove the transaxle, first check components like oil seals and replace them if necessary. For manual transaxle models, remove the clutch and inspect or replace the clutch components and release bearing. Make alignment marks on the flywheel and crankshaft to simplify replacement, as the bolt holes are slightly offset. Hold the flywheel/driveplate stationary while unscrewing the bolts; use a transaxle mounting bolt and a wide-bladed screwdriver to prevent turning. Remove each bolt in turn, ensuring new replacements are obtained for reassembly due to the severe stresses they endure. Carefully remove the heavy flywheel, noting that the driveplate for automatic transaxles is lighter. Clean the flywheel to eliminate grease and oil, inspecting for cracks, rivet grooves, burned areas, and score marks, with light scoring removable using emery cloth. Check for cracked and broken ring gear teeth and verify warpage with a straight-edge. Clean the mating surfaces of the flywheel and crankshaft, replacing the oil seal if leaking, especially in high-mileage engines. While the flywheel is off, clean its inboard face and the crankshaft speed/position sensor. For installation, ensure the engine/transaxle adapter plate is in place, align the flywheel/driveplate on the crankshaft using the marks made during removal, and install new bolts, tightening them by hand. Lock the flywheel using the disassembly method, tightening the bolts in a diagonal sequence and gradually increasing to the final torque in two or three stages. The remainder of reassembly follows the reverse of the removal process.
