  Q: How to Ensure Proper Timing Chain Installation on Chevrolet Silverado 3500?

  A: First you must remove the Oil Pump then turn the Crankshaft until the timing alignments match the Crankshaft and camshaft sprocket marks before continuing to prevent piston assembly or valve damage. Begin by removing both camshaft sprocket bolts then take out the camshaft sprocket and Timing Chain. The technician should utilize three tools to detach and replace components: j 8433 two jaw puller (J 8433), j 41816-2 Crankshaft end protector (J 41816-2) and j 41558 Crankshaft sprocket remover (J 41558). Additionally, the removal of the Crankshaft sprocket key may be necessary. Thorough cleaning and inspections should occur before installing the Timing Chain and sprockets when needed. Slide the key into the Crankshaft keyway until both key ends reach the measuring points. Seating operations should be completed using the j 41665 Crankshaft balancer and sprocket installer (J 41665) to fully position the sprocket against the Crankshaft flange after you align the sprocket keyway with the Crankshaft key and mount the Crankshaft sprocket at the Crankshaft front. Check that the sprocket alignment mark faces 12 o'clock by rotating it then verify both the locating pin's alignment with its hole and the correct meshing of sprocket teeth and Timing Chain. The timing alignment marks between the camshaft and Crankshaft sprockets need alignment where the camshaft sprocket's alignment mark faces the 6 o'clock position. To achieve correct mark alignment professionals may need to rotate the camshaft or Crankshaft sprockets before installing the camshaft sprocket bolts at a torque of 35 nm (26 ft. Lbs.), followed by reinstallation of the Oil Pump.
