A damaged retaining ring can lead to piston assembly failure during operation. This aftermarket replacement part references the CAT catalog and cross-references part number CT20802-51221. The ring functions as a mechanical fastener that secures the piston within its bore. If the ring fails, the piston may dislodge, causing sudden loss of compression or component separation. In a typical repair context, a worn or broken ring is often discovered when disassembling a piston assembly. Verify the serial number or application, then call (562) 693-7748.

Part number variants: CT20802-51221, ct20802-51221, CT2080251221, ct2080251221
