2008 Cadillac Escalade ESV Timing Chain

Do not push or pull on the reluctor wheel of the camshaft position (CMP) actuator during removal or installation. The reluctor wheel is retained to the front of the CMP actuator by 3 roll pins. Pushing or pulling on the wheel may dislodge the wheel from the front of the actuator. The actuator return spring is under tension and may rotate the dislodged reluctor wheel, causing personal injury. The sprocket teeth and timing chain teeth must mesh. The camshaft and the crankshaft sprocket alignment must be aligned properly.

You should ensure that the teeth of the J 42386-A mesh with the teeth of the engine flywheel, and do not turn the crankshaft assembly after the timing chain has been removed to prevent damage to the piston assemblies or the valves.
