Abstract
Methods and systems are provided for a phase control apparatus in a variable cam timing (VCT) system of an engine, the phase control apparatus having a locking pin coupled to a rotor vane and engageable with a locking pin recess in the phase control apparatus cover plate. In one example, a method for assembling the phase control apparatus may include positioning respective retarded side surfaces of the rotor vane and the housing in face-sharing contact while positioning respective retarded side surfaces of the locking pin and the locking pin recess in face-sharing contact and maintaining a backlash gap between only the advanced side surfaces of the locking pin recess.
