RING-RETAINING (Nissan NICK1818399)

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 NICK1818399. The ring-retaining type functions by seating into a groove to secure a shaft or bore assembly. A common failure consequence is that a worn or missing ring permits axial movement, causing misalignment or disengagement of adjacent parts. During routine service, a retaining ring may be found cracked or deformed from repeated load cycles. Verify the serial number or application, then call (562) 693-7748.
