Abstract

A cam phaser includes a rotor, a stator, and a cover. The rotor defines a first hole and a second hole and can rotate relative to the stator between a first intermediate position and a second intermediate position. The cover is mounted on the stator and defines a first lock pin seat and a second lock pin seat. The cam phaser includes a first lock pin and a second lock pin. The first lock pin can move along the first hole and into the first lock pin seat to lock the rotor relative to the stator at the first intermediate position. The second lock pin can move along the second hole and into the second lock pin seat to lock the rotor relative to the stator at the second intermediate position.
