This comprehensive inventory supports all your maintenance and repair needs, from large excavator parts to compact equipment hydraulic parts.
Product Knowledge: The Role of the TRAVEL-DEVICE (Final Drive)
The TRAVEL-DEVICE, also commonly known as the Final Drive, is a critical mechanical and hydraulic component located on each side of the undercarriage of a tracked excavator like the Hitachi ZX490-5A. Its primary function is twofold:
Reduction Gearbox: It uses a planetary gear set to dramatically reduce the speed of rotation from the hydraulic motor while significantly increasing the torque delivered to the sprocket.
Propulsion: The integrated hydraulic travel motor, powered by the main hydraulic pump, drives the reduction gearbox, which in turn rotates the sprocket to move the tracks and propel the machine.
A properly functioning TRAVEL-DEVICE is paramount for the excavator's traction, speed control, and overall maneuverability on various terrains. Regular maintenance and the use of high-quality replacement parts like the SWAFLY 9302718 are essential to prevent costly failures.
Engineering Machinery Component Glossary
Track Adjuster: A component in the undercarriage that maintains proper tension on the track chain. Example: Hitachi ZX350-5 track adjuster.
Boom Cylinder: A hydraulic cylinder mounted on the main frame (car body) used to raise and lower the main boom. Example: Hitachi ZX490LCH-5A Boom Cylinder.
Arm Cylinder: A hydraulic cylinder mounted on the boom used to move the arm (or dipper stick) in and out. Example: Hitachi ZX890LCH-5A Arm Cylinder.
Bucket Cylinder: A hydraulic cylinder mounted on the arm used to actuate the bucket (curl and dump). Example: Hitachi ZX670LCH-5G Bucket Cylinder.
Control Valve: The central component of the hydraulic system that directs fluid flow to actuators (cylinders, motors). It is installed in the main hydraulic block. Example: Hitachi ZX870-5G Control Valve.
Piston Pump: The main pump that generates the hydraulic flow and pressure for the entire system. Located in the engine bay. Example: Hitachi ZX70-5G Piston Pump.
Swing Device: A gearbox and hydraulic motor assembly that allows the machine's upper structure to rotate (swing). Installed in the center of the car body. Example: Hitachi ZX240-5A Swing Device.
Drive Motor: The hydraulic motor component of the travel device (final drive). Installed within the final drive housing. Example: Hitachi ZX400LCH-5A Drive Motor.
Cab Assembly: The operator's compartment, providing control and safety. Installed on the upper structure. Example: Hitachi ZX490LCH-6 Cab Assembly.
Engine Assembly: The internal combustion power source for the machine's hydraulic and electrical systems. Installed in the machine housing. Example: Hitachi ZX330-5A Engine.
These components are part of our extensive offering, supporting your needs for crawler excavator hydraulic parts, excavator undercarriage system maintenance, heavy duty travel motor parts, and hydraulic system troubleshooting kits.
Heavy Equipment Troubleshooting Tip
Problem: A Heavy Truck (e.g., Mercedes-Benz Actros 4160) experiences loss of power and rough running under load. The engine is an OM 502 LA.
Solution: This is often due to a fuel system issue, specifically clogged fuel filters or a failing fuel pressure regulator/pump.
Check the fuel filter service records; replace the primary and secondary fuel filters.
Inspect the low-pressure fuel pump for proper function and pressure output.
If the problem persists, check the high-pressure injection system, including unit injectors (PLD system), for faults or air intrusion, as this is critical for the OM 502 LA's performance.
