RETAINER - VALVE SPRING (Mitsubishi MB1016924)

MB1016924: A worn retainer can allow a valve spring to shift, leading to loss of valve timing or component separation. The retainer holds the valve spring in place against the valve stem, securing it during operation. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB1016924. The retainer's mechanical function is to maintain spring compression and prevent the spring from dislodging. A common failure consequence is that a cracked or deformed retainer may cause the spring to release, potentially allowing the valve to drop into the cylinder. Verify the serial number or application, then call (562) 693-7748. This part is cataloged as a retaining ring, which serves to lock the spring assembly in position.
