Installing a Hellcat pulley can significantly enhance your vehicle’s performance, allowing you to achieve over 750 rear-wheel horsepower (Rwhp) safely. This guide will walk you through the step-by-step process of installing a Hellcat pulley, ensuring that you have all the necessary tools and knowledge to complete the task effectively.
Tools and Materials Needed
- Hellcat pulley kit
- Socket set
- Torque wrench
- Ratchet
- Breaker bar
- Impact wrench (optional)
- Engine oil
- Safety glasses
- Gloves
Preparation Steps
Before starting the installation, ensure that your vehicle is parked on a flat surface and the engine is cool. Gather all the necessary tools and materials to avoid interruptions during the process.
1. Disconnect the Battery
For safety, disconnect the negative terminal of the battery to prevent any electrical issues while working on the engine.
2. Remove the Engine Cover
Using the appropriate socket, remove the bolts securing the engine cover. Carefully lift it off and set it aside.
Removing the Old Pulley
Now that you have access to the engine, it’s time to remove the old pulley. Follow these steps to ensure a smooth removal process.
1. Loosen the Serpentine Belt
Locate the tensioner pulley and use a ratchet or breaker bar to relieve tension on the serpentine belt. Slide the belt off the old pulley and set it aside.
2. Remove the Old Pulley
Using the appropriate socket, remove the bolts securing the old pulley. Once the bolts are removed, gently pull the pulley off the shaft. If it is stuck, you may need to use a puller tool.
Installing the New Hellcat Pulley
With the old pulley removed, you’re ready to install the new Hellcat pulley. Follow these steps carefully to ensure proper installation.
1. Prepare the New Pulley
Before installation, apply a small amount of engine oil to the pulley shaft. This will help with installation and ensure a proper fit.
2. Install the New Pulley
Align the new Hellcat pulley with the shaft and gently slide it into place. Ensure it is seated properly.
3. Secure the Pulley
Using the appropriate socket, tighten the bolts to secure the new pulley. Refer to the manufacturer’s specifications for the correct torque settings.
Reinstalling the Serpentine Belt
Once the new pulley is secured, it’s time to reinstall the serpentine belt. Follow these steps to ensure it is correctly positioned.
1. Position the Serpentine Belt
Refer to the belt routing diagram (usually found on the engine cover or in the owner’s manual) to correctly position the serpentine belt over the new pulley and other components.
2. Apply Tension
Using the ratchet or breaker bar, apply tension to the tensioner pulley and slide the serpentine belt back onto the tensioner. Ensure the belt is properly seated on all pulleys.
Final Steps
With the new pulley and belt installed, it’s time to complete the installation process.
1. Reinstall the Engine Cover
Place the engine cover back onto the engine and secure it with the bolts you removed earlier.
2. Reconnect the Battery
Reconnect the negative terminal of the battery, ensuring a secure connection.
3. Start the Engine
Start the engine and allow it to idle for a few minutes. Check for any unusual noises or issues with the serpentine belt.
Conclusion
Installing a Hellcat pulley can dramatically increase your vehicle’s performance. By following this step-by-step guide, you can achieve over 750 Rwhp safely and effectively. Always ensure to double-check your work and maintain your vehicle regularly to enjoy the benefits of your new pulley for years to come.
