Camshaft - LH: Removal

WARNING: This page is about a different car, the 2012 Ford F550 Super Duty and 2012 Ford F450 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The camshaft procedure must be followed exactly or damage to the valves and pistons will result.
  1. Position the crankshaft damper spoke at the 12 o'clock position and the timing mark indentation at the 1 o'clock position.

  6. Loosen and back off the LH camshaft sprocket bolt one full turn.
  7. NOTE: If servicing both camshafts, do not rotate the crankshaft or engine damage may occur. Camshaft position has been established in Step  8.
    NOTE: If the camshaft lobes are not exactly positioned as shown in illustration, the crankshaft keyway will require one full additional rotation to 12 o'clock. Do not rotate the crankshaft if servicing both camshafts.

  10. NOTE: The camshaft roller followers must be installed in their original locations or engine damage may occur. Record camshaft roller follower locations.
    NOTE: Do not allow the valve keepers to fall off the valve or the valve may drop into the cylinder. If a valve drops into the cylinder, the cylinder head must be removed. For additional information, refer to Cylinder Head .
    NOTE: It may be necessary to push the valve down while compressing the spring.

  13. Rotate the crankshaft clockwise, as viewed from the front, positioning the crankshaft damper spoke at the 6 o'clock position and the timing mark indentation at the 7 o'clock position.
  14. NOTE: Engine is not freewheeling. Camshaft procedure must be followed exactly or damage to valves and pistons will result.
    NOTE: The Timing Chain Locking Tool must be installed square to the timing chain and the engine block or engine damage may occur.
    NOTE: Front cover removed for clarity.
