Technical Glossary of Excavator Parts
Planetary Gear (行星齿轮): A gear system used in travel motors and gearboxes to provide speed reduction and torque multiplication.
Location: Inside travel motor gearbox. Example: Caterpillar CAT 312 Excavator Travel Motor Gearbox, Part Number: N/ASpeed Sensor (速度传感器): A sensor that monitors the rotational speed of the engine or other components.
Location: Engine flywheel housing or crankshaft. Example: Caterpillar CAT 320C Engine Speed Sensor, Part Number: 196-7973Swing Motor Seal Kit (回转马达油封套件): A set of seals used to prevent hydraulic fluid leakage in the swing motor, which controls the excavator's rotation.
Location: Inside the swing motor assembly. Example: Caterpillar E200B Swing Motor Seal Kit, Part Number: N/AAftercooler (后冷器): A heat exchanger that cools the compressed intake air from the turbocharger before it enters the engine.
Location: Between the turbocharger and intake manifold. Example: Caterpillar CAT 345C L Aftercooler, Part Number: 230-2967Pilot Gear Pump (先导齿轮泵): A hydraulic pump that provides pilot pressure to the hydraulic control valves.
Location: Attached to the main hydraulic pump or engine. Example: Caterpillar CAT 307 Excavator Pilot Gear Pump, Part Number: N/AAir Conditioning Belt (空调皮带): A belt that drives the air conditioning compressor.
Location: Engine accessory drive system. Example: CAT Caterpillar E320B Air Conditioning Belt, Part Number: 8410Upper Water Hose (上水管): A hose that carries coolant from the engine to the radiator.

Location: Attached to the excavator's undercarriage, driving the tracks. Example: Caterpillar CAT 305.5 Travel Motor Assembly, Part Number: N/ATurbocharger Intake Manifold (涡轮增压器进气歧管): Part of the engine's air intake system that distributes compressed air from the turbocharger to the cylinders.
Location: Between the turbocharger and engine cylinder head. Example: Turbocharger Intake Manifold for Caterpillar CAT Excavator 330D, Part Number: N/AFuel Filter (燃油滤清器): A filter that removes contaminants from the fuel before it reaches the engine.
Location: In the fuel line, typically near the engine. Example: Caterpillar Excavator CAT E330C Fuel Filter, Part Number: 1R-0762
Frequently Asked Questions
What are the common signs that my excavator's hydraulic cylinder seals need replacing?
Common signs include hydraulic fluid leaks around the cylinder, reduced cylinder performance (slow or weak movement), and visible damage or wear on the seals. Regular inspection is crucial.
How often should I replace the fuel filter on my Caterpillar excavator?
Fuel filters should be replaced according to the manufacturer's recommended service intervals, typically every 500 hours of operation or as indicated by fuel system performance issues. Always refer to your Caterpillar excavator's operation and maintenance manual.

Troubleshooting Tip: Excavator Engine Overheating
Problem: Excavator engine overheating during operation.
Possible Causes:
Low coolant level in the radiator or water tank.
Faulty thermostat preventing proper coolant circulation.
Clogged radiator core or water tank radiator (like Water Tank Radiator 245-9207).
Damaged or loose upper water hose or lower radiator hose.
Malfunctioning water pump.
Fan belt issues (e.g., Air Conditioning Belt 8410, if also driving the cooling fan).
Solution:
Check and replenish coolant level.
Inspect and test the thermostat; replace if faulty.
Clean the radiator core and water tank radiator to remove debris.
Examine water hoses for leaks or damage; replace if necessary.
Verify water pump functionality.
Check and adjust or replace the fan belt.
If overheating persists, consult a qualified mechanic for further diagnosis, which may include checking for internal engine issues.
