One New Aftermarket Replacement Planetary Gear for Caterpillar (Cat) 320B Excavators

This aftermarket replacement planetary gear fits the swing drive assembly on Caterpillar 320B-series hydraulic excavators. Planetary gears in the swing drive transmit torque from the swing motor through the reduction gearbox, enabling smooth upper-structure rotation under load. Replacing worn or damaged planetary gears restores proper swing function and prevents further drivetrain damage.
