Valve Spring Retainer Lock
Mitsubishi FUSO®

The Valve Spring Retainer Lock, also known as the Valve Keeper, is a small but important component in the engine of a commercial truck. It is responsible for holding the valve spring retainer in place, which in turn keeps the valve spring compressed and the valve closed. Without the Valve Spring Retainer Lock, the valve spring retainer could come loose, causing the valve to remain open or close improperly. This could lead to a loss of power, decreased fuel efficiency, and even engine damage. Made from high-quality materials, such as hardened steel or titanium, the Valve Spring Retainer Lock is designed to withstand the high pressures and temperatures of the engine. It is a critical part of the valve train system and must be installed correctly to ensure proper engine performance. Regular maintenance and inspection of the Valve Spring Retainer Lock can help prevent engine failure and prolong the life of the engine.
