A central follower is positioned in the passage and is configured for engagement with the central lobe. A first lateral follower is pivotally supported on a shaft extending through the first bore and is configured to engage the at least one lateral cam lobe. A latching mechanism is positioned on the follower body for selectively latching the lateral follower to the body.
