摘要

The arrangement (1) has a threaded bolt (5) provided coaxial to a rotation axis of a crankshaft (3) and fastening an actuator (2) to the crankshaft. The threaded bolt includes two external threads having different thread pitches, where the threads are thread- engaged with an internal thread (9) of the crankshaft and/or an internal thread of a bearing support (4) that presses the actuator against the crankshaft. The support has a stop collar for the threaded bolt, where the collar is provided adjacent to the thread of the support. An independent claim is also included for a method for mounting a flywheel or a flywheel part at a crankshaft of an internal combustion engine.
