Camshaft - LH: Camshafts: Removal

WARNING: This page is about a different car, the 2012 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan, can cause engine failure.
NOTE: If the RH camshafts are being serviced at the same time as the LH camshafts, remove the RH camshafts first. For additional information, refer to CAMSHAFT - RH  .
NOTE: If the components are to be reinstalled, they must be installed in their original location. Mark the components for installation into their original location.
  1. Remove the engine front cover. For additional information, refer to ENGINE FRONT COVER  .
  2. Using the crankshaft holding tool, rotate the crankshaft clockwise until the keyway is at the 12 o'clock position.

    4. NOTE: IF EITHER THE PRIMARY TENSIONER OR TIMING CHAIN TENSIONER ARM REQUIRE REPLACEMENT, BOTH THE PRIMARY TENSIONER AND TIMING CHAIN TENSIONER ARM MUST BE REPLACED. FAILURE TO REPLACE BOTH THE PRIMARY TENSIONER AND TIMING CHAIN TENSIONER ARM MAY RESULT IN OVERLOADING OF THE TIMING CHAIN AND UNDER CERTAIN CONDITIONS COULD LEAD TO TIMING CHAIN FAILURE.

  4. Remove the 2 bolts and the RH primary timing chain tensioner.
    5. NOTE: IF EITHER THE PRIMARY TENSIONER OR TIMING CHAIN TENSIONER ARM REQUIRE REPLACEMENT, BOTH THE PRIMARY TENSIONER AND TIMING CHAIN TENSIONER ARM MUST BE REPLACED. FAILURE TO REPLACE BOTH THE PRIMARY TENSIONER AND TIMING CHAIN TENSIONER ARM MAY RESULT IN OVERLOADING OF THE TIMING CHAIN AND UNDER CERTAIN CONDITIONS COULD LEAD TO TIMING CHAIN FAILURE.
    NOTE: It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to remove the RH timing chain tensioner arm. Return the crankshaft keyway to the 12 o'clock position after removing the RH timing chain tensioner arm.

  5. Remove the RH timing chain tensioner arm.
    6. NOTE: It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to remove the RH timing chain guide. Return the crankshaft keyway to the 12 o'clock position after removing the RH timing chain guide.
