RING - HOLE SNAP (CAT CT1S1638)

A damaged retaining ring can allow a shaft or bore component to shift, leading to mechanical failure. During assembly, a snap ring must seat fully in its groove to secure the part. Keeping a retaining ring in sound condition helps prevent unexpected disassembly under load. This aftermarket replacement part references the CAT catalog number CT1S1638. The ring functions as a hole snap type, designed to fit into an internal groove. A common failure consequence is that a worn or broken ring can release the retained part, causing operational stoppage. Verify the serial number or application, then call (562) 693-7748.
