The CMM-G Wind Turbine Gearbox Oil Changer is engineered specifically to perform a complete three-stage process for gearbox servicing in wind turbines: it drains old lubricant, performs an internal flushing with cleaning fluid, and refills the system with new oil. This ensures that the gearbox operates with clean, correctly specified oil, which is essential for reducing wear, minimizing downtime, and extending the operational life of drivetrain components.
