Workshop Technical Tip: Before installing the complete swing drive, it is mandatory to check the cleanliness and lubrication status of the swing ring gear. After installation, it is essential to prime the hydraulic motor housing with clean oil through the case drain port and fill the gearbox with gear oil (e.g., 80W90). Failure to bleed and prime the motor before the first start-up risks immediate seizure.
