  8. Verify that the key (3) is installed in the crankshaft.
    CAUTION:

    Do not rotate the crankshaft more than a few degrees independently of the camshafts. Piston to valve contact could occur resulting in possible valve damage. If the crankshaft needs to be rotated more than a few degrees, first remove the camshafts.

    CAUTION:

    Do not rotate the camshafts more than a few degrees independently of the crankshaft. Valve to piston contact could occur resulting in possible valve damage. If the camshafts need to be rotated more than a few degrees, first move the pistons away from the cylinder heads by rotating the crankshaft counterclockwise to a position 30° before-top-dead-center. Once the camshafts are returned to their top-dead-center position, rotate the crankshaft clockwise to return the crankshaft to top-dead-center.

  9. Verify that the number one cylinder piston is positioned at top-dead-center by aligning the dimple (2) on the crankshaft with the block/bearing cap junction (1).

  10. If the Camshaft Holders have been removed, verify that the camshafts are set at top-dead-center by positioning the alignment holes (1) vertically.
    NOTE:

    It may be necessary to rock the camshaft slightly (a few degrees) with a wrench (2) when installing the camshaft holder.

    CAUTION:

    Always reinstall timing chains so that they maintain the same direction of rotation. Inverting a previously run chain on a previously run sprocket will result in excessive wear to both the chain and sprocket.

  12. Place the primary chain onto the crankshaft sprocket (3) so that the arrow (2) is aligned with the plated link (1) on the timing chain.

  14. While maintaining this alignment, lubricate the idler sprocket bushing with clean engine oil and install the sprockets and timing chain on the engine. To verify that the timing is still correct, the timing chain plated link (6) should be located at 12:00 (1) when the dimple (5) on the crankshaft is aligned with the block/bearing cap junction (4).
  15. Install the idler sprocket retaining bolt (2) and washer (3) and tighten the bolt (2) to the proper torque specification. Refer to TECHNICAL SPECIFICATIONS .

  16. Reset the primary chain tensioner (2) by pushing back the tensioner piston and installing Tensioner Pin (special tool #8514A, Pins, Tensioner) (3).
  17. Install the primary chain tensioner to the engine block with two bolts (1) and tighten the bolts (1) to the proper

    Refer to TECHNICAL SPECIFICATIONS .

  18. Press the left side intake camshaft phaser onto the intake camshaft. Install and hand tighten the oil control valve (6).
    GC0144165Courtesy of CHRYSLER GROUP, LLC
    NOTE:

    The left side and right side cam chains are identical.

    CAUTION:

    Always reinstall timing chains so that they maintain the same direction of rotation. Inverting a previously run chain on a previously run sprocket will result in excessive wear to both the chain and sprocket.

  19. Drape the left side timing chain over the left side intake camshaft phaser and onto the idler sprocket (1) so that the arrow (3) is aligned with the plated link (2) on the cam chain.
    GC0144164Courtesy of CHRYSLER GROUP, LLC
  20. While maintaining this alignment, route the timing chain around the exhaust and intake camshaft phasers so that the plated links are aligned with the phaser timing marks (1). Position the left side camshaft phasers so that the arrows (3) point toward each other and are parallel to the cylinder head cover mounting surface (5). Press the exhaust cam phaser onto the exhaust cam, install and hand tighten the oil control valve (2).
  21. Install the (special tool #2025101090, Holder, Camshaft Phaser - Left-Front Cyl Head) (4) with the tool number facing up.
  22. Tighten the oil control valves (2) and (6) to the proper torque specification. Refer to TECHNICAL SPECIFICATIONS .
  23. Remove the Camshaft Phaser Holder (4).

  26. While maintaining this alignment, route the camshaft chain around the exhaust and intake camshaft phasers so that the plated links are aligned with the phaser timing marks (1). Position the right side camshaft phasers so that the arrows (3) point away from each other and the scribe lines (4) are parallel to the cylinder head cover mounting surface (6). Press the intake camshaft phaser onto the intake camshaft, install and hand tighten the oil control valve (2).
  27. Install the (special tool #2025102090, Holder, Camshaft Phaser - Right-Rear Cyl Head) (5) with the tool number facing up.
