Preparation
Before starting the installation, ensure that your engine is cool and that you have a clear workspace. Disconnect the battery to prevent any electrical issues during the installation.
Step 1: Remove the Old Camshaft
Begin by removing the valve covers and the intake manifold. This will allow you access to the camshaft. Next, remove the timing chain cover to expose the timing chain and the old camshaft.
Using your socket set, carefully remove the bolts securing the old camshaft. Take note of the order and location of the bolts for reinstallation.
Step 2: Prepare the New Camshaft
Before installing the new Comp Cams XR270HR camshaft, apply a thin layer of engine oil to the lobes and bearings. This will help reduce friction during the initial startup.
Step 3: Install the New Camshaft
Carefully insert the new camshaft into the engine block. Ensure that it aligns properly with the bearings. Use a camshaft installation tool to help guide it into place without damaging the bearings.
Step 4: Reinstall the Timing Chain
Once the camshaft is in place, reinstall the timing chain set. Make sure to align the timing marks correctly to ensure proper timing of the engine.
Step 5: Reassemble the Engine
After the timing chain is secured, reinstall the timing chain cover, intake manifold, and valve covers. Be sure to use new gaskets to prevent any leaks.
Step 6: Final Checks
Before reconnecting the battery, double-check all connections and ensure that everything is tightened to the manufacturer’s specifications using a torque wrench.
Step 7: Start the Engine
Reconnect the battery and start the engine. Allow it to idle for a few minutes while checking for any unusual noises or leaks. If everything sounds good, you have successfully installed your new camshaft!
