RING - PISTON (Komatsu KO4480265)

KO4480265: A damaged retaining ring can allow a piston to shift, leading to loss of compression or mechanical binding. This aftermarket replacement part references the Komatsu catalog and cross-references part number KO4480265. The ring secures the piston within its bore by snapping into a groove, preventing axial movement during operation. If the ring fails, the piston may dislodge, causing sudden stoppage or internal scoring. Keeping a retaining ring in sound condition helps maintain consistent piston alignment under load. The item ships at approximately 0.05 pounds. Verify the serial number or application, then call (562) 693-7748.
