O-RING (Mitsubishi MB2I9905)

MB2I9905: A damaged retaining ring can allow a shaft or bore component to shift out of position during operation. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB2I9905. The retaining ring functions as a mechanical fastener that seats into a groove to secure assembled parts axially. A common failure consequence is that a worn or broken ring may release the retained component, leading to sudden disassembly. During a routine disassembly, a technician might find a ring that has lost its spring tension and no longer holds. The item ships at approximately 0.01 POUNDS.
