Glossary of Construction Machinery Parts
Swing Motor Gearbox (回转减速器): A critical component in excavators that reduces the swing motor's high-speed output to a lower speed with higher torque, enabling the excavator to rotate its upper structure smoothly. Installed between the swing motor and swing bearing. Example: Swing Motor Gearbox for Caterpillar CAT320C Excavator, Part Number: 177-7171.
Travel Motor Gearbox (行走减速器): Part of the excavator's travel system, it converts the high-speed, low-torque output of the travel motor into low-speed, high-torque power to drive the tracks. Located within the undercarriage, connected to the travel motor and drive sprocket. Example: Travel Motor Gearbox for Caterpillar CAT E320L Excavator, Part Number: 135-5819.
Hydraulic Pump (液压泵): The heart of the hydraulic system, converting mechanical power into hydraulic energy to operate various excavator functions like digging, lifting, and swinging. Typically engine-mounted and supplies pressurized oil to the hydraulic system. Example: Hydraulic Pump for Caterpillar CAT320B Excavator, Part Number: 157-3165.
Hydraulic Cylinder (液压缸): Actuates the boom, arm, and bucket of the excavator using hydraulic pressure. Consists of a piston and cylinder, converting hydraulic pressure into linear motion. Example: Boom Cylinder for Caterpillar CAT320C Excavator, Part Number: 197-7781.
Solenoid Valve (电磁阀): Electrically controlled valve that directs hydraulic fluid flow within the system, controlling the operation of cylinders and motors. Integrated into the hydraulic valve block. Example: Solenoid Valve for Caterpillar CAT320D Excavator, Part Number: 246-6271.
Pressure Sensor (压力传感器): Monitors hydraulic pressure in different parts of the system, providing feedback to the control system for optimal operation and safety. Installed at various points in the hydraulic lines. Example: Pressure Sensor for Caterpillar CAT336D Excavator, Part Number: 366-9312.
Oil Cooler (机油冷却器): Dissipates heat from the hydraulic oil to maintain optimal operating temperature, preventing overheating and ensuring hydraulic system efficiency. Usually located in the hydraulic cooling system, often near the radiator. Example: Hydraulic Oil Cooler for Caterpillar CAT320B Excavator, Part Number: 141-5721.
Water Tank Radiator (水箱散热器): Cools the engine coolant to prevent engine overheating. Located at the front or side of the engine compartment. Example: Water Tank Radiator for Caterpillar CAT E320L Excavator, Part Number: 7Y-2109.
Fuel Stop Solenoid (燃油切断电磁阀): An electromagnetic switch that controls the fuel supply to the engine, used to stop the engine electrically. Mounted on the fuel injection pump. Example: Fuel Stop Solenoid for Caterpillar CAT 320B Excavator, Part Number: 1751-24E7U1B1S5.
Center Swivel Joint (中央回转接头): Allows hydraulic fluid to pass between the rotating upper structure and the non-rotating undercarriage, enabling continuous swing function. Located at the center of the swing bearing. Example: Center Swivel Joint for Caterpillar CAT336D Excavator, Part Number: 438-5484.
Frequently Asked Questions about Excavator Parts
Q: What are common signs that my excavator swing motor gearbox needs replacement?
A: Common signs include unusual noises during swing operation, slow or weak swing function, hydraulic leaks around the gearbox, and excessive play in the swing bearing.Q: How often should I replace hydraulic filters on my Caterpillar excavator?
A: Hydraulic filters should be replaced according to Caterpillar's recommended service intervals, typically every 500 to 1000 hours of operation, or as indicated by hydraulic system performance and oil analysis.Q: Can I use aftermarket parts on my Caterpillar excavator, and what are the benefits?
A: Yes, aftermarket parts from reputable suppliers like Growshine International offer a cost-effective alternative to OEM parts without compromising quality and performance. Benefits include reduced downtime and significant cost savings.
Troubleshooting Guide: Excavator Travel Motor Failure
Symptom: Excavator Track Not Moving or Moving Weakly
Possible Cause: Travel Motor Gearbox Failure
Detailed Troubleshooting Steps:
Initial Check: Inspect the tracks for obstructions and ensure the track tension is correct. Check hydraulic oil level and condition.
Hydraulic Pressure Test: Use a hydraulic pressure gauge to test the pressure at the travel motor. Low pressure indicates a potential pump or hydraulic line issue. Normal pressure but weak movement suggests a motor or gearbox problem.
Leakage Inspection: Examine the travel motor and gearbox for external hydraulic leaks. Significant leakage points to seal failures or component damage.
Gearbox Oil Drain and Inspection: Carefully drain the gearbox oil and inspect it for metal shavings or contamination. Metal particles indicate internal gear wear or failure.
Internal Gearbox Inspection (Requires Disassembly): If metal contamination is found, disassemble the gearbox to inspect gears, bearings, and shafts for wear, cracks, or breakage. Replace damaged components and seals.
Travel Motor Inspection: If the gearbox is not the issue, inspect the hydraulic travel motor itself for internal damage, such as worn pistons or cylinders.
Reassembly and Testing: Reassemble the gearbox and/or motor with new parts and seals. Refill gearbox with new oil. Test the travel function to ensure proper operation and pressure.
Note: For complex repairs, consult a qualified hydraulic technician.
