• Q: How to replace the Cam Gear and timing chain sprockets on 2003 Cadillac Escalade?

  A: The first step in Timing Chain and sprocket replacement includes taking out the Oil Pump before rotating the Crankshaft to match its marks with those on the cam and crank sprockets. After removing the Timing Chain, never turn the Crankshaft assembly to avoid piston assembly or valve damage. The first step includes removing camshaft sprocket bolts then proceeding with the removal of camshaft sprocket and Timing Chain. Utilizing the j8433 (Two Jaw Puller) as well as j41816-2 (Crankshaft End Protector) and j41558 (Crankshaft Sprocket Remover) will help you remove the Crankshaft sprocket followed by the removal of the Crankshaft sprocket key depending on requirements. Time the chain and its sprockets for any necessary cleaning or inspection process. Begin installation by inserting the key into the Crankshaft keyway and gradually push it forward until the key rests in both ends. Install the Crankshaft sprocket frontward on the Crankshaft with precise alignment of the key from the Crankshaft to the sprocket keyway before completing the installation using the j41665 (Crankshaft Balancer and Sprocket Installer). Rotate the Crankshaft sprocket so its alignment mark points to 12 o'clock while the camshaft sprocket locating pin should align with the sprocket alignment hole and the sprocket teeth should effectively engage the Timing Chain. Place the camshaft sprocket together with Timing Chain before adjusting either camshaft or Crankshaft sprockets to align their marks properly. The installation process ends by inserting the camshaft sprocket bolts then tightening them to 35 nm until they reach 26 ft. Lbs (torque) of resistance and reinstalling the Oil Pump.
