WEAR RING (CAT CT0397254)

CT0397254: A worn retaining ring can allow shaft components to shift, leading to mechanical misalignment or unexpected disassembly. This aftermarket replacement part references CAT as the OE maker and cross-references part number CT0397254. The retaining ring functions as a mechanical fastener that seats into a groove to secure parts axially on a shaft. A common failure consequence is that a broken or fatigued ring may release its hold, causing adjacent parts to slide out of position. In a typical usage context, these rings are installed during assembly to prevent lateral movement under vibration or load. The item ships at approximately 0.088 pounds.
