  Q: How to service the camshaft on Chevrolet Tracker?

  A:

  The first step to service the Camshaft is the disconnecting of the negative Battery Cable. Take away the Crankshaft Pulley, timing belt off the engine, the valve rocker arm cover. For the Camshaft Timing Belt pulley, you are advised to use a suitable tool to hold the Camshaft Timing Belt pulley and then extract the Camshaft Timing Belt pulley bolt and pulley. Next, remove the Timing Belt inner cover and the Camshaft sensor , as well as the ground wire at the Camshaft sensor housing and the wiring harness clamp. Put a shop rag beneath the Camshaft housing to capture any oil in advance of removing it. Take out the 3 Camshaft sensor housing bolts and the housing from the Cylinder Head. Remove all valve adjusting screw lock nuts and push the adjusting screws back to allow the rocker arms to be removed freely. Slowly undo the 12 bolts of the Camshaft housing in the prescribed order and extract the Camshaft from the cylinder hat then Camshaft oil seal. For an install, lubricate the cams, journals and oil seal with fresh engine oil, then install the Camshaft to the Cylinder Head. Apply engine oil to the housing bolts and then tighten them in the given order to 10 nm (89 inch lbs.). Put the Camshaft oil seal in until it is flush with the housing surface, and then re-attach the Timing Belt inner cover. While installing the Camshaft timing sprocket, make sure the pin on the Camshaft is inserted right in to the slot marked "e" on the sprocket. Secure the Camshaft timing sprocket by placing the Camshaft timing sprocket bolt and tighten it up to 60 nm (44 ft. Lbs). Mount and tighten Camshaft sensor housing with 10nm (89 inch lbs) and the Camshaft sensor with the ground wire fastening and tighten the sensor bolt to 10nm (89 inch lbs). Temporarily fit the valve rocker arm cover followed by the Timing Belt and then remove the valve rocker arm cover to adjust the valve lash. Finally, reinstall the valve rocker arm cover, crankshaft pulley, and reconnect the negative Battery Cable and tighten it to 15 nm (11 ft. Lbs.).
