One New Aftermarket Replacement Ring Gear for Komatsu PC200-Series Excavators
This aftermarket replacement ring gear (gear-ring) is a component of the swing reduction gearbox assembly on Komatsu (Komatsu) PC200-series hydraulic excavators. The swing reduction gearbox rotates the upper structure of the excavator on its undercarriage, and the ring gear is a key internal element of that planetary gear set. Replacing a worn or damaged ring gear restores proper swing function and prevents further drivetrain damage.
