The initial steps to remove the camshaft are disconnecting the cable from the negative battery terminal and relieving the fuel system pressure.

The steps for installing the camshaft are as follows:1. Lubricate the camshaft bearing journals and cam lobes with assembly lube.2. Slide the camshaft into the engine.3. Install the camshaft thrust plate.4. Install the balance shaft drive gear.5. Install the timing chain and sprockets.6. Lubricate the lifters with clean engine oil.7. Install the lifters in the block.8. Complete the installation in reverse order of removal.

To inspect the camshaft, the lobe height and base circle should be measured to determine the lobe lift. The results should be compared to the specifications, and the camshaft should be replaced if necessary. The camshaft bearing journals should also be inspected for wear and damage, and measured with a micrometer. The camshaft lobes should be checked for discoloration, score marks, chipped areas, and uneven wear.

After installing the camshaft, you should:1. Refill the cooling system.2. Change the engine oil and filter.3. Start the engine and check for leaks.

To remove the camshaft, start by disconnecting the cable from the negative battery terminal and relieving the fuel system pressure.

Before removing the lash adjusters, arrange to store them in a clearly labeled box. Remove the lash adjusters and camshaft retainer plate, and use a bolt as a handle to carefully pull out the camshaft. To inspect the camshaft, measure the lobe height and base circle to determine the lobe lift. Compare the results to the specifications and replace the camshaft if necessary. Inspect the camshaft bearing journals for wear and damage, and measure them with a micrometer. Check the camshaft lobes for discoloration, score marks, chipped areas, and uneven wear. Clean and inspect the lash adjusters for damage, wear, and proper function. Install the camshaft by lubricating the bearing journals and lobes with assembly lube, sliding it into the engine, and securing it with the camshaft thrust plate. Install the timing chain and sprockets, camshaft position sensor, and lash adjusters. Finally, refill the cooling system, change the oil, and install a new oil filter before starting and running the engine.

During inspection of the camshaft, you should: 1. Clean the lifter and camshaft with solvent. 2. Check for wear and damage on the lifter and camshaft. 3. Measure the journals and cam lobes for wear. 4. Replace the camshaft and bearings if they are damaged.
