O-RING (Nissan NI89140-00007)

NI89140-00007: A damaged retaining ring can allow assembled components to separate during operation, leading to mechanical failure. This aftermarket replacement part references Nissan as the OE maker and cross-references part number NI89140-00007. The retaining ring functions as a fastener that holds components in a fixed position on a shaft or in a bore. Its plain mechanical function is to seat into a groove and prevent axial movement of the installed part. A concrete generic failure consequence is that a worn or broken retaining ring may cause the retained component to shift, resulting in noise or loss of function. During routine service, a retaining ring should be inspected for deformation or cracks that could compromise its holding ability. Verify the serial number or application, then call (562) 693-7748.
