High-temperature and high-pressure resistance
Reduces hydraulic leakage and improves swing motor efficiency

The YNF16878 706-7G-01040 swing motor seal kit is designed to restore sealing performance in the swing motor of Komatsu PC270-8 excavators. This kit includes all major sealing components—high-pressure O-rings, oil seals, dust seals, and gaskets—manufactured from premium rubber compounds and engineered to withstand high temperature, hydraulic pressure, and continuous rotational load.
A worn sealing system commonly leads to hydraulic leakage, unstable swing movement, reduced torque output, and contamination inside the motor. Replacing the seals with YNF-quality components ensures smooth swing function, improved efficiency, and extended motor lifespan. Each seal is precision-molded for perfect compatibility with the 706-7G-01040 swing motor assembly.
Suitable for hydraulic repair centers, aftermarket distributors, and excavator maintenance fleets, this seal kit provides a reliable, cost-effective solution with stable performance and global availability.
