Understanding the Hitachi ZX170LC-5A Swing Device
The Swing Device (YB00002172RM) on the Hitachi ZX170LC-5A is the complete assembly responsible for rotating the upper structure (cab and boom) of the excavator. It typically consists of a hydraulic motor, a planetary gear reduction mechanism, and a brake system, all connected to the swing bearing (also known as the slewing ring) to achieve 360-degree rotation. Proper maintenance of the Swing Device is essential for the excavator's productivity and safety.
Essential Hitachi Excavator Part Definitions:
Travel Motor: Located in the Undercarriage, it converts hydraulic pressure into rotary motion to drive the tracks. Hitachi ZX330-3 Travel Motor
Control Valve: Located in the Main Frame, it directs hydraulic fluid flow to actuators like cylinders and motors. Hitachi ZX240-5A Control Valve
Track Adjuster: Located in the Undercarriage, it maintains the proper tension of the track chain. Hitachi ZX350-5 Track Adjuster
Boom Cylinder: Located on the Upper Structure/Attachment, it raises and lowers the main boom arm. Hitachi ZX450-3 Boom Cylinder
Arm Cylinder: Located on the Attachment, it controls the movement of the secondary arm (stick). Hitachi ZX290-5 Arm Cylinder
Bucket Cylinder: Located on the Attachment, it controls the opening and closing or tilting of the bucket. Hitachi ZX130-5A Bucket Cylinder
Piston Pump: Located in the Main Frame/Hydraulic System, it is the main source of hydraulic power. Hitachi ZX70-5A Piston Pump
Cabin Assembly: Located on the Upper Structure, it is the operator's compartment. Hitachi ZX210-3 Cabin Assembly
Engine: Located in the Upper Structure, it is the primary power source for the machine. Hitachi ZX330-3 Engine
H Links: Located in the Undercarriage, these are part of the track frame connection. Hitachi ZX210-5 H Links
Heavy Machinery Fault and Solution: Hitachi ZX330-5A Excavator
Fault: The Hitachi ZX330-5A experiences slow swing or complete failure of the swing motion, even when the engine is running at full power. This often indicates a problem within the Swing Device or the associated hydraulic circuit.
Analysis and Troubleshooting:
Check Hydraulic Pressure: Use a gauge to check the pilot pressure and main system pressure to the Swing Motor. Low pilot pressure can prevent the Control Valve from fully shifting.
Inspect Swing Brake: A stuck or improperly releasing Swing Brake is a common cause of slow swing. Check the brake solenoid and control signal.
Inspect Swing Motor and Gearbox: If hydraulic pressure is adequate, the issue may be internal to the Swing Motor (worn piston/cylinder block) or damaged reduction gears in the Swing Reduction Gearbox. Disassembly and inspection of the YB00002172RM type mechanism is required to identify mechanical failure.
Solution: If internal wear is confirmed, replace the damaged components (e.g., Swing Motor Rotary Group) or the entire Swing Device assembly with a high-quality SWAFLY replacement, such as the YB00002172RM.
