Sprocket(S), Timing Belt And Chain: Installation

GC0153382Courtesy of CHRYSLER GROUP, LLC
CAUTION:

When the timing belt is removed and the cylinder head is still installed, DO NOT rotate the camshaft or crankshaft without first locating the proper crankshaft position. Failure to do so will result in valve or piston damage.

  1. Align the crankshaft sprocket locator key to the crankshaft keyway and install the sprocket (1) with a new bolt (2) on the crankshaft. Hand tighten the bolt (2) at this time. The bolt (2) will be tightened to specification after the timing belt is installed.

    NOTE:

    If the original timing belt is being reused, install the belt so that it maintains the same direction of rotation as when it was removed.

  5. Install the timing belt starting with the crankshaft sprocket, then the water pump sprocket, finishing with the camshaft sprocket.
  6. Using transmission style 90° offset snap-ring pliers (3), rotate and adjust the timing tensioner so that the slots (2) are aligned. Tighten the lock nut (1) to 28 N.m (21 ft. lbs.).

  8. Remove the (special tool #10277, Tool, Camshaft Timing Locking) and the (special tool #10276, Tool, Crankshaft Timing Locking).
  9. Rotate the crankshaft clockwise at least two complete revolutions to center the timing belt on the sprockets.
  10. Verify that the slots (2) are still aligned. If required, loosen the tensioner lock nut (1), readjust the timing belt tensioner and tighten the lock nut (2) to 28 N.m (21 ft. lbs.).

    NOTE:

    Reinstall the timing locking tools to verify correct camshaft timing.

  11. Install the (special tool #10277, Tool, Camshaft Timing Locking) (1) to the rear of the camshaft. Install three bolts (2) and tighten to 20 N.m (15 ft. lbs.).

  12. Install the (special tool #10276, Tool, Crankshaft Timing Locking) (1) with three bolts (3) tightened to 25 N.m (18 ft. lbs.) and one bolt (2) tightened to 9 N.m (80 in. lbs.).
    NOTE:

    If the bolt (2) does not align with the lower timing belt cover mounting boss, the camshaft timing is not correct. Loosen the tensioner lock nut and the camshaft sprocket bolt and repeat this procedure.
