Flywheel
Smooths engine rotation and provides a clutch or transmission interface.
Bolted to the engine crankshaft at the gearbox end.
Rotational inertia moderates torque pulses; dual-mass designs add controlled torsional isolation.
A rotating energy reservoir smoothing uneven pushes.
Rattle or vibration may involve the flywheel, clutch, mounts or engine running quality.
Use the exact gearbox and axle service guidance. Loads, seals, lubricant condition and driving use influence wear.
An accessible mount or seal differs from internal transmission work. Gearbox identification and diagnosis are essential to a useful quote.
Many BMW manual drivetrains use a dual-mass flywheel, but the fitted design must be confirmed.
BMW rear-drive, front-drive and xDrive applications as equipped; layouts differ by platform.
