    CAUTION: Refer to Torque Reaction Against Timing Drive Chain Caution .
    NOTE:
    • Use an open-end wrench at the camshaft hex to prevent camshaft/engine rotation.
    • DO NOT remove the camshaft position actuator bolt at this time.
  7. Loosen the camshaft position actuator bolt.

  8. Unscrew the EN-48313  so the legs of the tool are retracted. See Special Tools .
  9. Insert the EN-48313  between the camshaft actuators, rearward of the timing chain until the top line that is scribed in the body of the tool (1) is adjacent to the top surface of the cylinder head (2). See Special Tools . This is the approximate installed position.

    NOTE: The engine front cover is removed for clarity in the following graphics, but NOT required to perform the procedure.
  10. Ensure that the feet (2) on the legs of the tool are facing the front of the engine.
  11. Partially expand the legs (1) of the EN-48313  by turning the T-shaped handle clockwise. See Special Tools .
  12. Continue expanding the EN-48313  until the feet (2) contact the timing chain. See Special Tools . Do not tighten at this time.

    NOTE:
    • Ensure that the foot (1) of the EN-48313  is engaged into one of the link pockets to prevent chain slippage during tightening of the EN-48313  . See Special Tools .
    • Do not allow the body of the EN-48313  to rotate when tightening the T-handle. See Special Tools .
  13. Hand tighten the EN-48313  . See Special Tools .
    14. CAUTION: Refer to Torque Reaction Against Timing Drive Chain Caution .
  14. Use an open end wrench on the hex cast into the body of the EN-48313  and hand tighten the T-handle. See Special Tools .
    15. CAUTION: Refer to Torque Reaction Against Timing Drive Chain Caution .
  15. Use an open end wrench on the hex cast into the right intake and exhaust camshafts and rotate the camshafts towards each other in order to create slack in the chain between the actuators.

    NOTE: Ensure that the camshaft timing chain and the camshaft position actuators are marked for proper assembly.
  17. Mark the timing chain and the respective locations on camshaft position actuators (15-18).
  18. Remove the camshaft position actuator bolt.
  19. Remove the camshaft bearing caps and the camshaft. Refer to Camshaft Removal - Right Side .
