PISTON ASSEMBLY (Komatsu KO304-43-33520)

A damaged piston assembly can disrupt the conversion of fluid pressure into linear motion. This aftermarket replacement part references the Komatsu catalog number KO304-43-33520. 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 worn seals, which reduces system pressure and causes sluggish or incomplete movement. During operation, the piston's surface condition directly affects the seal's ability to maintain a tight barrier. The item ships at approximately 0.278 pounds. Verify the serial number or application, then call (562) 693-7748.
