Timing Chain & Gears


Removal & Installation


2.7L Engine

To Remove:



  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.

  2. Remove or disconnect the following:

    • Upper intake manifold

    • Cylinder head covers, crankshaft vibration damper, and timing chain cover



    CAUTION
    When aligning timing marks, always rotate engine by turning the crankshaft. Failure to do so will result in valve and/or piston damage.



david :

  1. Align crankshaft sprocket timing mark to mark on oil pump housing the mark on oil pump housing is 60°ATDC of #1 cylinder.


    CAUTION
    When the timing chain is removed and the cylinder heads are still installed, DO NOT rotate the camshafts or crankshaft without first locating the proper crankshaft position. Failure to do so will result in valve and/or piston damage



  2. Remove or disconnect the following:

    • Primary timing chain tensioner from right cylinder head

    • Camshaft position sensor from left cylinder head

    • Chain guide access plug from left cylinder head



  3. Starting with the right camshaft sprocket, remove the sprocket attaching bolts.

  4. Remove or disconnect the following:

    • Camshaft damper (if equipped) and sprocket

    • Left side camshaft sprocket attaching bolts and remove sprocket

    • Lower chain guide and tensioner arm

    • Primary timing chain




 

david :

To Install:

david :

If removed, install right and left side short chain guides.



  • Torque to 250 inch lbs. (28 Nm)

david :

  1. Align crankshaft sprocket timing mark to the mark on oil pump housing.

    NOTE: Lubricate timing chain and guides with engine oil before installation.



  2. Place left side primary chain sprocket onto the chain so that the timing mark is located in-between the two (plated) timing links.

  3. Lower the primary chain with left side sprocket through the left cylinder head opening.

    NOTE: The camshaft sprockets can be allowed to float on the camshaft hub during installation.



  4. Loosely position left side camshaft sprocket over camshaft hub.

  5. Align timing (plated) link to the crankshaft sprocket timing mark.

  6. Position primary chain onto water pump drive sprocket.

  7. Align right camshaft sprocket timing mark to the timing (plated) link on the timing chain and loosely position over camshaft hub.

  8. Verify that all chain timing (plated) links are properly aligned to the timing marks on all sprockets.

  9. Install or connect the following:

    • Left side lower chain guide and tensioner arm

      1. Torque to 250 inch lbs. (28 Nm)


    • Chain guide access plug to left side cylinder head.

      1. Torque to 15 ft. lbs. (20 Nm)


      NOTE: To reset the primary timing chain tensioner, engine oil will first need to be purged from the tensioner.





david :



    • Purge oil from timing chain tensioner using the following procedure:

    • Place the check ball end of tensioner into the shallow end of Special Tool 8186 or equivalent.

    • Using hand pressure, slowly depress tensioner until oil is purged from tensioner.



  1. Reset timing chain tensioner using the following procedure:

david :



    • Position cylinder plunger into the deeper end of Special Tool 8186 or equivalent.

    • Apply a downward force until tensioner is reset.


    CAUTION
    Ensure the tensioner is properly reset. The tensioner body must bottom against the top edge of Special Tool 8186. Failure to properly perform the resetting procedure may cause tensioner jamming.



  1. Install or connect the following:

    • Reset chain tensioner into the right cylinder head

    • Tensioner retaining plate and tighten bolts

      1. Torque to 105 in. lbs. (12 Nm)




  2. Starting at the right cylinder bank, first position the camshaft damper (if equipped) on camshaft hub, then insert a 3/8" square drive extension with a breaker bar into intake camshaft drive hub. Rotate camshaft until the camshaft hub aligns to the camshaft sprocket and damper attaching holes. Install the sprocket attaching bolts.

    • Torque to 250 inch lbs. (28 Nm)



  3. Turn the left side camshaft by inserting a 3/8" square drive extension with a breaker bar into intake camshaft drive hub and rotate camshaft until the sprocket attaching bolts can be installed.

    • Torque to 250 inch lbs. (28 Nm)



  4. Rotate engine slightly clockwise to remove timing chain slack, if necessary.

david :

  1. Activate the timing chain tensioner by using a flat bladed pry tool to gently pry tensioner arm towards the tensioner slightly. Then release the tensioner arm. Verify the tensioner is activated (extends).

  2. Install or connect the following:

    • Timing chain cover, crankshaft vibration damper, and cylinder head covers

    • Camshaft position sensor and connect electrical connector

    • Upper intake manifold




NOTE: After installation of a reset tensioner, engine noise will occur after initial start-up. This noise will normally disappear within 5-10 seconds.
