Camshaft - LH: Installation

WARNING: This page is about a different car, the 2014 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
  1. NOTE: Lubricate the camshafts with clean engine oil prior to installation.

    Install the LH intake and exhaust camshafts in the neutral position. Align the D-slots as shown in the illustration.

    G09541174
  2. Install the 8 camshaft bearing caps and the 16 bolts. Do not tighten the bolts at this time.
  3. Install the LH front camshaft bearing mega cap and the 4 bolts. Do not tighten the bolts at this time
    G09541175
  4. Tighten the bolts in the sequence shown below in 2 stages.
    • Stage 1: Tighten to 6 Nm (53 lb-in).
    • Stage 2: Tighten an additional 45 degrees.

  5. NOTE: Intake camshaft shown, exhaust camshaft similar.

    Install the VCT  system oil filter in the intake and exhaust camshafts.

    G07409030
  6. Install the secondary timing chain onto the LH VCT  assemblies. Align the colored links on the secondary timing chain with the timing marks on the VCT  assemblies as shown in the illustration.
    1. The timing mark on the intake VCT  assembly should align between the 2 consecutive colored links.
    2. The timing mark on the exhaust VCT  assembly should align with the single colored link.
      G07408958
  7. Install the LH VCT  assemblies and the secondary timing chain onto the LH camshafts to a position 2 mm (0.078 in) from fully seated. The timing mark on the exhaust VCT  assembly should be in the 11 o'clock position.
    G09541179
  8. NOTE: It may be necessary to rotate the exhaust camshaft slightly (using a wrench on the flats of the camshaft) to seat the VCT  assemblies onto the camshafts.

    Rotate the secondary timing chain tensioner 90 degrees so the ramped area is facing forward and fully seat the VCT  assemblies onto the camshafts.

    • If the secondary timing chain is not centered over the tensioner, reposition the VCT  assemblies until they are fully seated on the camshafts.
      G09541180
  9. NOTE: Use a wrench on the flats of the camshaft to hold the camshafts while tightening the VCT  assembly bolts.

    Install the 3 LH intake VCT  assembly bolts and the 3 LH exhaust VCT  assembly bolts.

    • Tighten to 15 Nm (133 lb-in) plus an additional 90 degrees.
      G09541181
  10. Install the LH primary timing chain.
    • Align the colored link on the timing chain with the timing mark on the LH VCT  assembly.
      G09541182
  11. Align the remaining colored link on the timing chain with the timing mark on the crankshaft sprocket.
    G07408963
  12. NOTE: It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to install the LH timing chain guide. Return the crankshaft keyway to the 9 o'clock position after installing the LH timing chain guide.

    Install the LH timing chain guide and bolt.

    • Tighten to 10 Nm (89 lb-in).
      G09541184
  13. NOTE: It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to install the LH timing chain tensioner arm. Return the crankshaft keyway to the 9 o'clock position after installing the LH timing chain tensioner arm.

    Install the LH timing chain tensioner arm.

    G09541185
    NOTE: Complete the following 3 steps on both the LH and RH primary timing chain tensioners.
  14. NOTE: Do not compress the ratchet assembly or damage to the tensioner will occur.

    Compress the primary timing chain tensioner plunger, using an edge of a vise.

    G07408966
  15. Using a small screwdriver or pick, push back and hold the ratchet mechanism, then push the ratchet arm back into the tensioner housing.
    G07408967
  16. Install a suitable pin into the hole of the tensioner housing to hold the ratchet assembly and plunger in place during installation.
    G07408968
  17. Install the LH primary timing chain tensioner and 2 bolts.
    • Tighten to 10 Nm (89 lb-in).
    • Remove the holding pin from the tensioner.
      G07408969
  18. Using the crankshaft holding tool, rotate the crankshaft clockwise until the crankshaft keyway is at the 12 o'clock position.
    G07408970
  19. Install the RH primary timing chain.
    • Align the colored link on the timing chain with the timing mark on the RH VCT  assembly.
      G09541191
  20. Align the remaining colored link on the timing chain with the timing mark on the crankshaft sprocket.
    G07408976
  21. NOTE: It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to install the RH timing chain guide. Return the crankshaft keyway to the 12 o'clock position after installing the RH timing chain guide.

    Install the RH timing chain guide and bolt.

    • Tighten to 10 Nm (89 lb-in).
      G09541193
  22. NOTE: It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to install the RH timing chain tensioner arm. Return the crankshaft keyway to the 12 o'clock position after installing the RH timing chain tensioner arm.

    Install the RH timing chain tensioner arm.

    G09541194
  23. Install the RH primary timing chain tensioner and 2 bolts.
    • Tighten to 10 Nm (89 lb-in).
    • Remove the holding pin from the tensioner.
      G09541195
  24. With the crankshaft keyway still at the 12 o'clock position, verify the timing mark alignment is correct.
