PIER 24-42996 REC24-42996

Function and technical context

Spring 24-42996 is a precision spring component integrated into the timing system of Mercury, Mariner and MerCruiser engines. This spring maintains the necessary tension in the valve mechanisms, ensuring precise closing and opening during each combustion cycle. Its correct operation is essential to preserve engine timing, avoid compression leaks and ensure optimal performance of the variable valve timing system in direct fuel injection engines.

When to replace this part?

Distribution springs can lose elasticity after thousands of hours of operation, causing incomplete valve opening, progressive loss of power, cold starting difficulties and increased fuel consumption. It is recommended to check the condition of the springs during each scheduled maintenance and replace them if a weakening of the tension is detected. Preventive replacement of this component prevents damage to timing chains, camshafts and cylinder heads, repairs that are considerably more expensive than the spring itself.
