O-RING (Hyundai HN3966716)

HN3966716: A damaged retaining ring can allow assembled components to separate under load. During disassembly, a retaining ring may deform or break, leading to loss of preload. Keeping a retaining ring in sound condition helps maintain axial positioning of shafts and bores. The Hyundai catalog reference HN3966716 identifies this aftermarket replacement part. This O-ring type retaining ring provides a plain mechanical function of securing parts against axial movement. A concrete generic failure consequence is that a broken ring can cause sudden disengagement of a shaft or bearing assembly. Verify the serial number or application, then call (562) 693-7748.
