Engineering Machinery Parts Explained
Excavator Track Roller
Installed on the undercarriage of excavators to support and guide the track chain. Example: Komatsu PC300-8 Track Roller.
Turbocharger
Mounted on the engine to increase power output by forcing compressed air into the combustion chamber. Example: Volvo D16F Turbocharger.
Hydraulic Cylinder
Located in the boom and arm of excavators to provide lifting and digging force. Example: CAT 320D Hydraulic Cylinder.
Fuel Injection Pump
Installed in the engine to deliver precisely measured fuel to the cylinders. Example: Cummins ISX15 Fuel Injection Pump.
Starter Motor
Mounted on the engine to initiate the combustion process by turning over the engine. Example: John Deere 6175R Starter Motor.
Transmission Control Valve
Located in the transmission system to regulate hydraulic flow for gear changes. Example: Allison 4500 Transmission Control Valve.
Final Drive
Installed on the track system to provide reduction and torque multiplication. Example: Hitachi ZX350 Final Drive.
Radiator
Mounted in front of the engine to cool the circulating coolant. Example: MAN TGX Radiator.
Swing Bearing
Located between the upper structure and undercarriage of excavators to enable rotation. Example: Kobelco SK350 Swing Bearing.
Brake Caliper
Mounted on the wheel assembly to apply braking force through friction. Example: Scania R730 Brake Caliper.
Troubleshooting Guide: Liugong 915E Excavator Hydraulic System Issue
Problem Description
The Liugong 915E excavator shows weak digging force and slow operation cycles. The machine has an operating weight of 13,800 kg and engine power of 76.2 kW :cite[1].
Diagnosis Steps
Check hydraulic fluid level and condition
Inspect main pump pressure using pressure gauge
Test relief valve settings
Examine pump regulator function
Check for leaks in hydraulic system
Solution
Replace worn main hydraulic pump with genuine Liugong parts. The Liugong 915E uses the Kawasaki K5V series axial piston pump which is known for high efficiency, low noise, and reliability :cite[3]. After replacement, bleed the hydraulic system and test operation at various pressure settings.
Prevention
Regular maintenance of the hydraulic system including fluid changes every 2,000 hours, filter replacement, and periodic pressure testing can prevent similar issues. The E-series excavators feature improved maintenance accessibility with parallel radiator groups for easier cleaning and replacement :cite[3].
