4722649 Original Excavator Wire Harness for Hitachi ZX200-5G

Part number 4722649 is the original wiring harness specially designed by Hitachi for the ZX200-5G hydraulic excavator. It is the core signal and power harness that connects key hydraulic electronic control components such as the main control valve, pilot control unit, or walking motor. As a designated component of the original factory, its length, connector specifications, and pin definitions are perfectly matched with the equipment circuit layout

This product is a main road harness with heavy-duty spiral corrugated tube protection. The harness body is tightly wrapped in high-strength black spiral corrugated tube, providing top-level wear resistance, compression resistance, torsion resistance, and waterproof and dustproof capabilities. It is designed for chassis or engine compartment environments with severe vibration, narrow space, and muddy water. One end of the black circular connector has a locking buckle, and the other end of the gray rectangular connector is labeled with a part number. The difference in color and shape of the connector is designed to prevent accidental insertion by the original factory

Inspection cycle: Every 250 working hours, check the corrugated pipe of the wiring harness for cracks, dents, loose joints, oil or water stains. Fault diagnosis: If there is a malfunction in the relevant control functions (such as walking or working actions), after ruling out other causes, the conductivity of the wiring harness can be measured. Replacement timing: Once the wiring harness has damaged bellows, exposed internal wires, or damaged joints, it must be replaced as a whole
