PISTON ASSEMBLY (Komatsu KO304-43-33610)

A worn piston assembly can disrupt the conversion of fluid pressure into linear motion. This aftermarket replacement part references the Komatsu catalog and cross-references part number KO304-43-33610. The piston assembly functions as a moving component within a cylinder, transferring force through a sealed bore. A common failure consequence is internal leakage past the piston seals, reducing system pressure and causing erratic movement. During a rebuild, technicians often inspect the piston surface for scoring or wear that compromises sealing. The item ships at approximately 0.278 pounds. Verify the serial number or application, then call (562) 693-7748.
