The VALVE COLLET with the part number HCB147-1979 is a small but crucial engine component, typically used in internal combustion engines. Valve collets, also known as valve keepers or valve retainers, are used to secure the valve spring to the valve stem, ensuring that the valve operates correctly and maintains proper valve lash (clearance). The specific part number, HCB147-1979, serves as a unique identifier, allowing individuals and mechanics to identify and order the correct valve collet for a particular engine or vehicle model. Each part number corresponds to specific sizing, material, and design of the valve collet, ensuring a precise fit and optimal performance within the engine’s valvetrain. Valve collets play a crucial role in the engine’s overall performance by securely retaining the valve springs, allowing the valves to open and close at the right times during the engine’s operation. Maintaining the correct valve lash and preventing valve spring-related issues is essential for the engine’s proper functioning.
