K3V112 hyundai 210 excavator
Repairing the main pump of a Hyundai 210 excavator, Kawasaki K3V112 model, requires precise inspection of hydraulic components and internal parts. First, the pump must be removed from the system and an initial check for leaks and mechanical damage performed. Then, the shaft, control rings, and vanes are measured with high-precision tools such as micrometers and gauges. In case of corrosion or cracks, components should be replaced according to JIS or ISO standards. Additionally, the pump’s operating pressure must be checked and adjusted to 250 bar with a flow rate of 160 liters per minute to ensure optimal hydraulic system performance.
Replacing high-pressure O-rings and seals must be done carefully to prevent hydraulic leaks. After assembly, the pump is tested on a hydraulic test bench under 250 bar pressure and 50°C oil temperature. Vibration, noise, and oil flow are checked, and any deviations from factory specifications are corrected. This repair process not only extends the pump’s service life but also ensures hydraulic system efficiency reaches up to 95 percent of factory standards.
