  Q: How to service and repair the Cam Gear and sprocket on GMC Sonoma?

  A: The service process for camshaft gear and sprocket includes first removing the engine front cover then the Crankshaft position sensor reluctor ring. A 7/16-20 x 1 inch bolt should be installed into the Crankshaft closing. Avoid using the Crankshaft balancer bolt or a longer bolt since they can damage the threads. Use a 7/16-20 x 1 inch bolt to turn the Crankshaft until both sprocket timing marks match and the number four cylinder reaches its top dead center (TDC) position during compression. Remove the camshaft sprocket bolts before taking out the camshaft sprocket and Timing Chain. The Crankshaft gear remover (J 5825-A) helps to remove Crankshaft sprocket and subsequent removal of Crankshaft balancer key. Thoroughly clean each component while also inspecting both sprockets and the camshaft Timing Chain for any indications of wear or breaking. When installing the Crankshaft balancer key fit it into the Crankshaft keyway while maintaining a parallel position or minor angle. Use the Crankshaft gear installer (J 5590) to put the Crankshaft sprocket in position by aligning its keyway with the balancer key. Mount the camshaft sprocket with its reference mark facing the 6 o'clock direction while the Crankshaft sprocket stays at the 12 o'clock position. Torque the camshaft sprocket bolts to 25 nm (18 ft. Lbs.) settings.after placing the Crankshaft position sensor reluctor ring in position next to the balancer key you should use Crankshaft gear installer (J 5590) to fully position it. To finish the installation you must remove the bolt from the Crankshaft and set the engine front cover into place.
