Example: CAT 320C Joystick Controller, Part Number: 206-3303.
Pressure Sensor (压力传感器 - Yālì chuángǎnqì)
Pressure sensors monitor the hydraulic pressure within the excavator's systems, ensuring safe and efficient operation. They provide feedback to the control system to regulate hydraulic functions. Installed at various points within the hydraulic lines and components.
Example: CAT 320D Pressure Sensor, Part Number: 434-3436.
Water Pump (水泵 - Shuǐbèng)
The water pump circulates coolant through the engine and radiator to maintain optimal engine temperature and prevent overheating. Mounted on the engine block, driven by belts or gears.
Example: CAT 320C Water Pump, Part Number: 236-4413.
Radiator Core (散热器芯 - Sànrè qì xīn)
The radiator core is the heat exchanger component of the radiator, dissipating heat from the engine coolant to prevent overheating. Located at the front or side of the engine compartment, part of the radiator assembly.
Example: CAT D8N Radiator Core, Part Number: 7E-9595.
Starter Motor (起动马达 - Qǐdòng mǎdá)
The starter motor is an electric motor that cranks the engine to start the excavator. Bolted to the engine block, engaging with the flywheel to initiate engine rotation.
Example: CAT 307B Starter Motor, Part Number: 103-5287.
Temperature Sender (温度传感器 - Wēndù chuángǎnqì)
The temperature sender measures the engine temperature and sends this information to the temperature gauge or engine control unit. Typically installed in the engine block or cylinder head, in contact with coolant.
Example: CAT 225B Temperature Sender, Part Number: 8N-3844.
Travel Gearbox (行走变速箱 - Xíngzǒu biàosù xiāng)
The travel gearbox reduces the speed and increases the torque from the travel motor to the tracks, providing the necessary power and control for excavator movement. Integrated into the undercarriage, connected between the travel motor and the tracks.
Example: CAT 320D Travel Gearbox, Part Number: 296-6299.
Muffler Silencer (消声器 - Xiāoshēng qì)

Example: CAT 320D Muffler Silencer, Part Number: 324-4172.
Troubleshooting Tips for Excavator Parts
Why is my excavator losing hydraulic power?
Loss of hydraulic power can be due to several reasons, including a faulty hydraulic pump, internal leaks in cylinders or valves, low hydraulic fluid levels, or a clogged hydraulic filter. Check the fluid level and filter first, then inspect for leaks and consider testing the hydraulic pump pressure.
What causes an excavator engine to overheat?
Engine overheating can be caused by a malfunctioning water pump, a clogged radiator core, a faulty thermostat, low coolant levels, or a damaged cooling fan. Inspect the coolant level and check for leaks, ensure the cooling fan is operating, and examine the radiator for blockages.
Why are my excavator tracks moving slowly or unevenly?
Slow or uneven track movement can be caused by issues with the travel motor, travel gearbox, or hydraulic supply to the travel motors. Check for leaks in the travel motor and hydraulic lines, inspect the travel gearbox oil level, and ensure the hydraulic pump is delivering sufficient pressure to both travel motors.

Detailed Fault and Solution: Travel Motor Failure
Fault Description: Excavator tracks on one side are not moving, or moving very slowly, while the engine and hydraulic pump seem to be functioning normally. This indicates a potential failure in the travel motor assembly.
Possible Causes:
Internal Leakage in Travel Motor: Worn seals or damaged internal components can cause hydraulic fluid to leak internally, reducing the motor's efficiency and power output.
Damaged Gearbox: Gear damage within the travel gearbox can prevent proper power transmission to the tracks.
Clogged or Damaged Hydraulic Lines: Restrictions or damage to the hydraulic lines supplying the travel motor can limit fluid flow.
Faulty Relief Valve: A malfunctioning relief valve in the travel motor circuit could be bypassing hydraulic pressure.
Troubleshooting and Solution:
Hydraulic Pressure Test: Use a pressure gauge to test the hydraulic pressure at the travel motor inlet. Compare readings to the manufacturer's specifications. Low pressure indicates a problem upstream (pump, lines, or control valve) or internal leakage in the motor.
Leakage Inspection: Visually inspect the travel motor and hydraulic lines for external leaks. Internal leakage requires disassembly and inspection of the motor.
Gearbox Check: Drain the oil from the travel gearbox and inspect for metal shavings or debris, indicating gear damage.
Component Inspection (If Disassembled): If the travel motor is disassembled, inspect seals, bearings, gears, and other internal components for wear or damage. Replace worn or damaged parts.
Hydraulic Line and Valve Inspection: Check hydraulic lines for blockages or damage. Inspect the relief valve for proper function.
Replacement: In cases of severe internal damage or gearbox failure, replacing the entire travel motor assembly (e.g., Travel Motor Assembly 0995351 for Caterpillar CAT Excavator E110B) may be the most efficient solution.
Note: Hydraulic system troubleshooting should be performed by qualified technicians. Always refer to the Caterpillar service manual for specific procedures and safety precautions.
