How to inspect and replace the rear main/flywheel seal and flywheel on BMW M3?

Inspect the rear main/flywheel seal for leakage when inspecting the flywheel. Replace as necessary. The flywheel should be inspected for ring gear damage, fluid contamination, warpage flatness and thickness variations, speed and reference sensor damage, and surface irregularities such as scoring, cracking, and signs of overheating. If the flywheel's clutch surface shows signs of deterioration or wear, it should be replaced. Symptoms of an improper flywheel clutch surface include clutch chatter during engagement and disengagement, poor shifting qualities, or grabbing. If the rear main/flywheel seal is leaking or the flywheel needs to be replaced, it should be replaced at this time. An oil-saturated clutch disk can cause clutch slippage, burning odors, and poor disengagement and engagement qualities. Dual mass flywheels, such as the one installed on E36 models, have a viscous coupling that can be checked with the pressure plate installed or removed. To check the viscous coupling, place a protective cloth over the pressure plate and rotate it in a clockwise direction until the flywheel barely begins to move. Match mark the pressure plate and the outer body of the flywheel. Then, rotate the pressure plate in a counterclockwise direction until the flywheel barely begins to move and match mark it again. The pressure plate should be able to be moved between the two match marks without excessive force or looseness.

BMW M3 Flywheel

The BMW M3 Flywheel aids the crankshaft by storing energy between combustion strokes and ensuring smooth power delivery and start-up. During every generation, the Flywheel bolts to the crank, and the outer ring gear permits the starter to crank the engine until ignition takes over. The component is also provided with a friction face that is applied by the clutch disc for gripping. Throughout the history of the car, there have been two main styles of Flywheel, the solid Flywheel and the dual mass Flywheel. Although the two Flywheels work toward the same goal of smoothness and stability, they differ when you take a peek at their construction. The solid version is a one-piece disc that can often be lightly resurfaced when heat marks and grooves appear. The dual mass type splits into primary and secondary parts with spring dampers that absorb vibration. However, these cannot be machined. If failure or excess runout occurs, then they need replacing. A Flywheel swap is normally required because of clutch wear, warped faces, or chipped ring teeth. When the damping springs within a dual mass fail, noise and shake warn the driver. The earlier models of BMW kept a simpler solid unit, but later M3 models received a dual mass for quieter driveline manners. When the right component is chosen, it keeps any BMW M3 eager to rev smoothly off the line.
