  Caution
Do not use an impact wrench or pneumatic wrench to remove bolts -B-: this would severely damage the dual-mass flywheel. Bolts -B- must always be removed by hand.
–  Rotate flywheel -A- so that bolts -B- are aligned centrally behind the holes -arrows-.
–  When unscrewing bolts -B-, make sure the bolt heads do not contact the flywheel -arrows- because this would damage the flywheel when the bolts are turned further.
