Camshaft Sprockets

WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: The camshaft sprockets are keyed and not interchangeable from side to side because of the camshaft position sensor pick-up.

  1. Install camshaft sprockets onto the camshafts. Install NEW  sprocket attaching bolts into place. The 255 mm (10 in.) bolt is to be installed in the left camshaft and the 213 mm (8 3/8 in.) bolt is to be installed into the right camshaft. Do not tighten the bolts; tightened at later step.  Camshaft sprocket (2, 7) marks (1, 8) should be aligned with the marks on the cover at both sprockets. See Fig 1.

  2. Install the camshaft thrust plates (1) and o-ring (3). Tighten bolts (2) to 28 N.m (250 in. lbs.). See Fig 2.
  3. Install the timing belt starting first at the crankshaft sprocket (10), then to remaining components in a counterclockwise direction.
  4. Install the belt around the last sprocket. Maintain tension on the belt as it is positioned around the tensioner pulley (11). Each camshaft sprockets mark should still be aligned with the rear cover marks. See Fig 1.
    NOTE: For timing belt tensioner reset procedure, (Refer to ENGINE/VALVE TIMING/TIMING BELT AND SPROCKETS - TIMING BELT - REMOVAL) .
  5. Hold the tensioner pulley against the belt and install the reset (pinned) timing belt tensioner into the housing. Tighten attaching bolts to 28 N.m (250 in. lbs.).
  6. Remove tensioner retaining pin to allow the tensioner to extend to the pulley bracket.
  7. Using a dial indicator, position the number 1 piston at TDC.
  8. Hold the camshaft sprocket hex with a 36 mm (1 7/16 in.) wrench and tighten the camshaft bolts to the following:
    1. Right side = 102 N.m (75 ft. lbs.) +90° turn
    2. Left side = 102 N.m (75 ft. lbs.) +90° turn
  9. Remove dial indicator and install spark plug.
  10. Remove Special Tools 6642.
  11. Install front timing belt cover. (Refer to ENGINE/VALVE TIMING/TIMING BELT/CHAIN COVER(S) - INSTALLATION) .
