Chrysler 300/300 Touring/300C, Dodge Magnum. Manual — part 1564
CAMSHAFT SPROCKETS
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.
2. Install the camshaft thrust plates (1) and o-ring (3).
Tighten bolts (2) to 28 N·m (250 in. lbs.).
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.
NOTE: For timing belt tensioner reset procedure,
(Refer to 9 - ENGINE/VALVE TIMING/TIMING BELT
AND SPROCKETS - TIMING BELT - REMOVAL).
