Preparation Steps
Begin by parking your Hellcat on a flat surface. Ensure the engine is cool before starting the installation. Disconnect the battery to prevent any electrical issues.
Remove the Engine Cover
The engine cover needs to be removed to access the supercharger pulley. Use your socket set to remove the bolts securing the cover. Carefully lift it off and set it aside.
Access the Supercharger Pulley
Locate the supercharger pulley on the front of the engine. You may need to remove additional components such as the intake tube or other accessories to gain better access.
Removing the Stock Pulley
Once you have clear access, it’s time to remove the stock pulley. Use the pulley puller to carefully extract it from the supercharger. Make sure to follow the tool’s instructions for proper use.
Inspect the Area
Before installing the aftermarket pulley, inspect the area for any debris or damage. Clean the surface to ensure a proper fit.
Installing the Aftermarket Pulley
Now it’s time to install the aftermarket pulley. Align it carefully with the supercharger shaft and press it into place. Ensure it is seated properly.
Torque Specifications
Refer to the manufacturer’s specifications for the correct torque settings. Use your torque wrench to tighten the pulley bolt to the specified torque to avoid any issues during operation.
Reassembly
After the pulley is securely installed, reassemble any components you removed earlier. Ensure all bolts are tightened to the manufacturer’s specifications.
Reconnect the Battery
Reconnect the battery and ensure all connections are secure. Double-check your work to prevent any electrical issues.
Testing the Installation
Start the engine and listen for any unusual noises. Allow the engine to idle for a few minutes to ensure everything is functioning properly. Take the car for a test drive to experience the increased horsepower.
Tips for Success
- Follow the manufacturer’s instructions for the pulley kit.
- Consider using a professional mechanic if unsure about any step.
- Keep a clean workspace to avoid losing small parts.
- Document your process for future reference.
By following these steps and tips, you can successfully install an aftermarket pulley on your Hellcat and enjoy the benefits of increased horsepower and improved performance.
