O-RING INTERPART (CAT CT21001-00105-INT)

CT21001-00105-INT: A damaged retaining ring can allow assembled components to separate under load, leading to mechanical failure. During inspection, a retaining ring may show signs of distortion or cracking that compromise its holding force. This aftermarket replacement part references the CAT catalog and cross-references part number CT21001-00105-INT. The retaining ring functions as a mechanical fastener that seats in a groove to secure parts axially. A common failure consequence is that a worn ring can no longer prevent shaft or housing components from shifting position. Keeping a retaining ring in sound condition helps maintain the intended assembly integrity. Verify the serial number or application, then call (562) 693-7748.
