Abstract:
A partial assembly process for a vane-type cam phaser. A pulley/sprocket is loaded onto a first camshaft-shaped fixture with a cam nose extending beyond the length of an actual cam nose such that a phaser rotor containing a locking bolt, when mounted onto the cam nose, is displaced axially from the pulley/sprocket by an amount sufficient to set the axial engagement of the bolt upon final assembly. A stator is loaded onto the pulley/sprocket and is rotated clockwise until it contacts the rotor, thereby removing all rotational and radial lash from the system. One or more axial holes are bored through the pulley/sprocket and stator and a locking pin such as a roll pin is inserted to permanently pin the stator to the pulley/sprocket. Finally, the partially-assembled phaser is removed from the cam-like fixture, the rotor is fully seated against the pulley/sprocket, the locking bolt is withdrawn from the pulley/sprocket, the rotor is rotated to an intermediate position, and the phaser cover is added to the assembly.
