Section 15 (2.7L Engine (Service Information)): Camshaft(S): Description
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.
The assembled fabricated camshafts are composed of five bearing journals machined onto a hollow steel tube. The camshafts are secured in the cylinder head (6) by the camshaft bearing caps (1)&(2). Six steel lobes, a secondary timing drive sprocket, and a primary sprocket/thrust flange are pressed onto the camshaft tube using a unique assembly process. Camshaft end play is controlled by the primary camshaft sprocket attachment flange on the intake camshafts (7) and by a thrust flange on the exhaust camshafts (3). The intake camshafts are driven by the primary chain. The exhaust camshafts (3) are driven by the intake camshafts (10) through a secondary chain (11). The secondary chain tensioner (7) keeps tension on the secondary chain (11).
