Installing Carrillo connecting rods is a crucial step for any serious drag racer looking to build a high-performance engine capable of handling 700+ horsepower. This guide will walk you through the necessary steps to ensure a successful installation.
Tools and Materials Needed
- Torque wrench
- Socket set
- Ratchet
- Engine assembly lube
- Connecting rod bolts
- Cylinder head gasket
- Clean rags
- Engine stand
- Safety glasses
Preparation Steps
Before beginning the installation process, ensure that you have a clean workspace and all necessary tools at hand. This will help to streamline the installation and reduce the risk of errors.
1. Remove the Old Connecting Rods
Start by removing the engine from the vehicle and placing it on an engine stand. Carefully remove the cylinder head and any other components obstructing access to the connecting rods.
Next, use a socket and ratchet to remove the bolts securing the old connecting rods to the crankshaft. Carefully slide the old rods off the crankshaft and set them aside.
2. Inspect the Crankshaft and Cylinder Walls
Before installing the new Carrillo connecting rods, inspect the crankshaft and cylinder walls for any signs of wear or damage. Clean the surfaces thoroughly to remove any debris or oil.
Installing Carrillo Connecting Rods
Now that the old rods are removed and the surfaces are clean, you can begin the installation of the Carrillo connecting rods.
1. Apply Assembly Lube
Generously apply engine assembly lube to the bearings of the Carrillo connecting rods. This step is essential for ensuring proper lubrication during the initial startup.
2. Position the Connecting Rods
Carefully position the connecting rods over the crankshaft. Ensure that the orientation of the rods matches the manufacturer’s specifications, with the correct side facing the crankshaft.
3. Secure the Connecting Rods
Insert the connecting rod bolts through the rod and into the crankshaft. Hand-tighten the bolts to hold the rods in place temporarily.
4. Torque the Bolts
Using a torque wrench, follow the manufacturer’s specifications to torque the connecting rod bolts to the appropriate settings. This step is crucial to ensure the rods are securely fastened.
Final Steps
After the connecting rods are installed, there are a few final steps to complete before reassembling the engine.
1. Reinstall the Cylinder Head
Place a new cylinder head gasket on the engine block and carefully position the cylinder head back onto the block. Secure it with the appropriate bolts, following the manufacturer’s torque specifications.
2. Reassemble Other Components
Reattach any other components that were removed during the disassembly process, such as the intake manifold and exhaust headers. Ensure all connections are tight and secure.
3. Perform a Final Inspection
Before starting the engine, perform a final inspection of your work. Check for any loose bolts, leaks, or other potential issues that could arise during operation.
Conclusion
Installing Carrillo connecting rods can significantly enhance the performance of your drag racing engine. By following this step-by-step guide, you can ensure a proper installation that will support your 700+ horsepower build.
