2000 Chevrolet Tracker Camshaft Parts Questions & Experts Answers

• Q: How to replace the intake camshaft and lash adjusters on 2000 Chevrolet Tracker?

  A: Disconnection of the negative Battery Cable serves as the first step for intake camshaft and lifter replacement. First remove the Timing Chain housing and then take out the camshaft Timing Chain together with the intake camshaft sprocket. The Crankshaft should be rotated by 90 degrees to avoid valve and piston collisions before looseness of intake camshaft bearing caps and subsequent removal of both bearing caps and intake camshaft. You must store these valve lifters in clean engine oil with the camshaft section facing down until installation while also keeping them from any disassembling or forcing on the valve side. The j26900-2 outside micrometer (J26900-2) must measure the camshaft lobe height and replacement is needed if the minimum height of 40.202 mm (1.5827 inch) is not met. The j8001 dial indicator set (J8001) with the j26900-13 magnetic base (J26900-13) should measure the camshaft runout. The camshaft must be replaced when the runout exceeds 0.10 mm (0.0039 inch). The examination of camshaft bearing caps and journals for wear or damage will require the replacement of the Cylinder Head in this case. Install the camshaft by gently placing it but do not rotate it while checking with plastic gauging material. Place each camshaft bearing cap into its designated position before tightening it to 11 nm (97 inch lbs.) in three successive stages. Check the oil clearance of the gauging plastic according to specification values to determine component replacement needs. Use j26900-2 to check valve lifter position and its correct relation with the valve lifter bore. The valve lifter bore needs engine oil flushing before filling the valve lifters with oil and their correct installation into their original positions. Install the camshaft after aligning its keyway with the timing mark while lubricating the journals with oil. Adjust the camshaft components to match their guide pin alignment positions before installing the bearing caps in sequence to a torque of 11 nm (97 inch lbs.). The bearing caps of the camshaft should go into place followed by tightening them in order before adding the intake camshaft sprocket and Timing Chain with subsequent installation of the Timing Chain housing. One should let the valves settle for thirty minutes after installation before starting the engine at 2000 rpm to remove trapped air from the lifters. Check for tapping again and change the defective lifter when it does not stop. The negative Battery Cable needs to be reconnected as the last step.
