A dual body rocker arm comprises an outer arm, an inner arm, a substantially cylindrical pivot axle, a pivot foot and a first and second pivot foot retaining ring. The inner arm is disposed between side arms of the outer arm. The pivot axle is mounted to both the inner and outer arm. The pivot foot has a cylindrical axle interfacing surface and a valve tip interface. Retaining rings mount the pivot foot to the axle, allowing partial rotation of the pivot foot about the axle. Interfering protrusions on the retaining rings limit the range of motion of the pivot foot. A pivot foot having at least one interfering block is configured to restrict motion of the pivot foot by interfering with at least one interfering tab. |
