Caution: Do not push or pull on the reluctor wheel of the camshaft position (CMP) actuator during removal or installation. The reluctor wheel is
retained to the front of the CMP actuator by 3 roll pins. Pushing or pulling on the wheel may dislodge the wheel from the front of the actuator. The
actuator return spring is under tension and may rotate the dislodged reluctor wheel, causing personal injury.
10. Use care to install the actuator completely onto the front of the camshaft. Position your fingers onto the face of the actuator sprocket and push the
actuator onto the front of the camshaft. Never push on the reluctor wheel when attempting to install the actuator.
