    NOTE:
    • Properly locate the CMP actuator onto the locating pin of the camshaft.
    • The sprocket teeth and timing chain must mesh
    • The camshaft and the sprocket alignment marks MUST be aligned properly.
    • Do not use the CMP solenoid valve again. Install a NEW valve during assembly.
  9. Identify the alignment hole (1) in the rear face of the CMP actuator and the locating pin (2) on the front face of the camshaft.

  10. Install the CMP actuator and timing chain (1). Use care to install the actuator completely onto the front of the camshaft. Position 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.
    11. Fig 10: Inspecting For Proper Installation Of CMP Actuator And Timing Chain

    NOTE:

    It is possible to push the camshaft rearward when installing the CMP actuator. Verify that the camshaft lobes are centered in the valve lifter bores after the CMP actuator is installed.

  11. Locate a straight edge across the front face of the engine block and inspect for proper installation of the CMP actuator and timing chain. With the CMP actuator properly and completely installed onto the front of camshaft, the timing chain will not protrude beyond the front face of engine block.

    CAUTION:

    Refer to Component Fastener Tightening Caution .

  12. Install a NEW CMP actuator solenoid valve (1). With the CMP actuator properly positioned onto the camshaft, the CMP actuator solenoid valve can be threaded completely into the camshaft using light hand pressure. Tighten by hand until snug.
    1. First pass 65 N.m (48 lb ft).
    2. Final pass 90 degrees.
    13. Fig 12: CMP Actuator Sprocket And Crankshaft Sprocket Alignment Marks

    CAUTION:

    Refer to Fastener Caution .

  14. Install the right side bolt (1) into the timing chain tensioner and tighten both bolts to 30 N.m (22 lb ft).
  15. Install oil pump. Refer to Oil Pump, Screen, and Crankshaft Oil Deflector Replacement .
