O-RING (CAT CT1916-05003)

A worn retaining ring can lead to component separation during operation. This aftermarket replacement part references CAT as the OE maker and cross-references part number CT1916-05003. The retaining ring functions as a mechanical fastener that holds assembled components in place within a bore or on a shaft. A common failure consequence is that a broken or missing ring allows parts to shift, causing misalignment or disassembly. During service, a technician may find the ring has lost tension or become deformed. Verify the serial number or application, then call (562) 693-7748.
