PENTASTAR ENGINE (3.6L V6) IDLER SPROCKET

Tuesday may 2nd 2023.
I am working on a 2011 Dodge Charger.This Dual Overhead Cam engine has 4 timing chains. One for the camshafts on the driver side to the idler sprocket, 1 for the camshafts on the passenger side to the idler sprocket, 1 going between the idler sprocket and the crankshaft and a chain going from the crankshaft sprocket to the oil pump sprocket. The top and middle gears in this picture are for the camshaft banks. The large gear in this picture goes to the crankshaft. This picture is of the BOTTOM (during timing mark alignment) of the idler sprocket. At the top, on the large gear there is a dimple. During alignment that dimple should be pointing straight up. The arrow on the crankshaft sprocket should be pointing straight down during alignment. The idler sprocket to crankshaft chain has gold plated links that lineup with these dimples.
