Preparation Steps
Before beginning the installation process, it is crucial to prepare your workspace and gather all necessary tools and materials. Ensure that your engine is cool and that you have a clean, organized area to work in.
1. Disconnect the Battery
Start by disconnecting the negative terminal of the battery to prevent any electrical shorts while working on the engine.
2. Remove the Engine Cover
If your engine has an aftermarket cover or any accessories that obstruct access to the camshaft, remove them carefully to expose the engine components.
Removing the Old Camshaft
With the engine prepared, you can begin the process of removing the old camshaft. Follow these steps closely to ensure a smooth transition.
1. Remove the Timing Chain Cover
Unbolt the timing chain cover and carefully remove it. Be ready to catch any oil that may spill out during this process.
2. Take Off the Timing Chain
Remove the timing chain and gears. Make sure to note the orientation and position of the components for reinstallation.
3. Unbolt the Old Camshaft
Now, unbolt the old camshaft from its position. This may require a socket set and some patience, as the bolts can be tight.
4. Remove the Camshaft
Carefully slide the old camshaft out of the engine block. Inspect it for wear and damage before disposing of it.
Installing the New Performance Camshaft
With the old camshaft removed, you can now proceed to install the new Mopar 440 performance camshaft.
1. Apply Camshaft Lubricant
Before installation, apply a generous amount of camshaft lubricant to the new camshaft to ensure proper break-in and reduce wear.
2. Insert the New Camshaft
Carefully slide the new camshaft into the engine block, ensuring it aligns with the bearings and other components.
3. Bolt Down the Camshaft
Once in place, bolt down the camshaft securely. Use a torque wrench to ensure that the bolts are tightened to the manufacturer’s specifications.
4. Reinstall the Timing Chain and Cover
Reattach the timing chain and gears, making sure they are properly aligned. Then, reinstall the timing chain cover, securing it with bolts.
Final Steps
After the new camshaft is installed, complete the final steps to ensure everything is in working order.
1. Replace Gaskets
Replace any gaskets that were removed during the process to prevent leaks. Ensure a proper seal before moving on.
2. Change Oil and Filter
It’s essential to change the oil and filter after installing a new camshaft. This helps to remove any debris and ensure the engine runs smoothly.
3. Reconnect the Battery
Reconnect the negative terminal of the battery, ensuring a secure connection.
4. Start the Engine
Finally, start the engine and let it idle for a few minutes. Listen for any unusual noises and check for leaks. If everything sounds good, take your vehicle for a test drive to experience the performance gains!
Conclusion
Installing a Mopar 440 performance camshaft can be a rewarding project that leads to significant horsepower gains. By following these step-by-step instructions, you can enhance your vehicle’s performance and enjoy the thrill of driving with increased power. Remember to take your time and ensure each step is completed correctly for the best results.
