SPRING (CAT CT1921-64248)

CT1921-64248: A worn retaining ring can allow assembled components to separate under load, leading to mechanical failure. This aftermarket replacement part references the CAT catalog and carries the cross-reference number CT1921-64248. The retaining ring functions as a spring-like fastener that holds parts in position on a shaft or in a bore. When the ring loses tension, it may no longer secure the assembly, causing unintended movement or disengagement. During routine service, a technician might find the ring deformed or cracked from repeated stress cycles. Verify the serial number or application, then call (562) 693-7748.
