For 324-7380 3247380 Piston Skirt CAT C9 C-9 E330D Split Piston Assembly

The 324-7380/3247380 piston skirt is a core accessory designed specifically for the split piston assembly of CAT C9, C-9 series engines and E330D excavators. As a key supporting structure of the piston, its main functions are to bear the piston side pressure, guide the piston to reciprocate in the cylinder, and effectively dissipate the heat generated during the piston operation.

We select high-strength aluminum alloy material, add silicon, copper and other reinforcing elements to improve material rigidity and wear resistance. After precision casting and CNC machining, hard anodizing treatment is applied to form a hard oxide film on the product surface, which not only enhances wear resistance but also effectively isolates direct erosion of high-temperature gas. This piston skirt is produced in strict accordance with CAT's original technical standards, with dimensional accuracy controlled within ±0.04mm, which perfectly matches the piston body and cylinder liner. No additional processing or adjustment is required during installation, and the normal working performance of the piston assembly can be restored by direct assembly. Whether in high-intensity operation scenarios such as mining and construction, it can ensure stable piston movement, reduce engine abnormal noise, power reduction and other problems caused by piston skirt wear, and extend the overall service life of the engine.
