PREASSEMBLY OF A CAMSHAFT PHASER
A camshaft phasing system ( 10 ) for an internal combustion engine ( 6 ) includes a camshaft ( 16 ) and a camshaft phaser ( 15 ) that is axially slid onto the camshaft ( 16 ) and that has stator ( 34 ) and a rotor ( 36 ) driven by the stator ( 34 ), whereby the rotor ( 36 ) is mounted rotatably relative to the stator ( 34 ). A bushing ( 26 ) that is secured on the camshaft ( 16 ) is provided, whereby the camshaft phaser ( 15 ) is tightened on the camshaft ( 16 ) against the bushing ( 26 ). Moreover, a drive has an internal combustion engine and such a camshaft phasing system.
