Installing a COMP Cams camshaft is a critical process that requires attention to detail and adherence to manufacturer specifications. This guide provides a step-by-step explanation of the installation process, based on the official documentation and technical recommendations from the manufacturer. By following these instructions, users can ensure the proper setup of their camshaft, minimizing the risk of failure and maximizing performance.
The installation process begins with inspecting the new camshaft and its components for damage. This includes checking the lobes and distributor gear for any signs of wear or deformation that may have occurred during shipping. Users are also advised to compare the stamped numbers on the camshaft with the specification card to confirm that the correct component is being installed.
Cleaning is another essential step in the process. The distributor gear should be lightly wire brushed with mineral spirits or an equivalent solvent to remove any debris or contaminants. This helps ensure that the components function smoothly once installed.
Before inserting the camshaft into the engine, all lobes and the distributor gear must be coated with COMP Cams® Cam & Lifter Installation Lube (Part #103). This lube should be applied in a thin, even layer to avoid over-application, which could lead to performance issues or mechanical failure. The cam bearing journals should also be coated with conventional SAE 30 or 40 wt. oil to facilitate smooth operation.
The timing chain and gear set are also critical to the installation. It is recommended to replace the existing timing chain, as it may be stretched beyond its service limits or machined to retard cam timing. A new timing chain ensures that the camshaft operates in alignment with the engine's design specifications. During installation, the cam sprocket can be used as a handle to assist in rolling the cam into place, reducing the need for excessive force and minimizing the risk of damage to the components.
Once the camshaft is in place, users should pay close attention to the installation of the camshaft retaining plate, if applicable. This component must be secured according to the torque specifications provided in the engine manual. Proper tightening ensures that the camshaft remains in its intended position, preventing misalignment and subsequent performance issues.
Degreeing the camshaft is not strictly necessary for the engine to function, but it is highly recommended to ensure optimal performance. COMP Cams advises using the intake centerline method, which is considered the simplest and most effective approach for degreeing a new camshaft. This process helps correct any machining errors or tolerances that may affect camshaft timing, ensuring that the engine performs as intended.
Users are also reminded to inspect and replace lifters when necessary. For flat tappet cams, it is essential to use new COMP Cams® lifters and to properly dispose of the old ones. Reusing old lifters may void the camshaft warranty and increase the risk of engine damage. With roller cams, users may reuse the lifters, but they should inspect them thoroughly for signs of wear or looseness.
Throughout the installation process, cleanliness is emphasized as a key factor in preventing component failure. The cleaner the new components are before installation, the better the chances of long-term reliability. Users should also avoid excessive force when inserting the camshaft into the engine and ensure that no assembly lube is wiped away during the process.
In summary, the installation of a COMP Cams camshaft involves a series of precise steps that must be followed to ensure the component functions correctly. From inspecting and cleaning the parts to applying the appropriate lubricants and securing the timing chain, each step contributes to the overall performance and longevity of the engine. Users should refer to the manufacturer’s documentation for additional details and torque specifications specific to their model.
Conclusion
The installation of a COMP Cams camshaft is a detailed and methodical process that requires careful attention to the manufacturer’s instructions. By following the outlined steps—ranging from component inspection and cleaning to lubrication and timing chain installation—users can ensure that their camshaft is properly set up for optimal performance. Emphasizing cleanliness, correct lubrication, and adherence to torque specifications are essential to achieving a successful installation. While degreeing the cam is not mandatory, it is recommended to fine-tune the engine’s timing for the best results. With these considerations in mind, users can confidently proceed with the installation, knowing they are taking the necessary steps to protect their engine and maximize its potential.
