O-RING (Komatsu KO3EB-04-48140)

A damaged retaining ring can allow assembled components to separate under load, leading to mechanical failure. During disassembly, a retaining ring may deform or break, making reuse unsafe. Keeping a retaining ring in sound condition helps maintain axial positioning of shafts and bores. This aftermarket replacement part references the Komatsu catalog number KO3EB-04-48140. The part type is a retaining ring, which functions as a removable fastener that seats in a groove to secure components. A common failure consequence is that a worn or improperly seated ring can cause sudden disengagement of a shaft or bearing. Verify the serial number or application, then call (562) 693-7748.
