O-RING (CAT CT2100100105)

CT2100100105: A damaged retaining ring can allow assembled components to separate during operation, leading to mechanical failure. This aftermarket replacement part references CAT as the OE maker and cross-references part number CT2100100105. The retaining ring functions as a fastener that holds components in position within a bore or on a shaft. 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 ring may cause the retained part to dislodge, resulting in sudden loss of function. Keeping a retaining ring in sound condition helps maintain secure assembly under normal working loads. Verify the serial number or application, then call (562) 693-7748.
